Last one ...
I built a 400 SB Chevy and put it in my '79 4x4 and ran down 2 batteries trying to start it.
It starts better when you put the hot wire to the distributor. That engine was already broke in by the time it did start !!

Gary-

Right where both cables come through the "firewall" they both go through that double clamp. The cable closest to the engine is the throttle cable and it appears to be about half way out of the clamp, or not seated well. This would be in line with your problem losing power or running irratically. I'd get this corrected and see what that does.

KenTUCK - sorry if I said the same thing you were getting at, but I must not have understood you suggestions to Gary S.

Wayne S - the double clamp is where I was leaning at 1st. I agree in the 3rd pic it looks like the Throttle cable may have slipped out, but in the other 3 it appears to be in place, at least to me. Gary does need to check this 1st and make sure the cable is not slipping back and forth in the clamp.

Gary S, and all (especially KenTUCK) - make sure that double clamp is really clamped down tight, and make sure both cables don't move in the clamp by moving the Throttle and Choke controls on the dash back and forth. Now, unless my eyes are deceiving me, it looks like there's a BIG ole KINK in the Governor Spring. Not sure that would cause the problem if the spring still basically works, but it might be. Otherwise, I'm wondering is that throttle cable wire is slipping past the hole in the lever it's connected in. Can't tell from the pic but that could cause a "no high speed" condition.

Gary - we need to know if the engine is revving up to full throttle as it used to. That's key to determining the problem. Not clear from your other messages but sounded as tho you've got idle and slightly over idle. Let us know.

If you don't get this before you leave I still feel certain we'll get to the bottom of this problem (probably be something from that ole Genius KenTUCK tho).

Thanks,

<font color="000000">Hey, Boys </font><font color="aa00aa">There's sharks in these waters!</font> I double checked and that's not pink, it's purple. Think about it. I have. At this point in time I've got a red (marronish Murray) Blue (Ford/Jacobsen), Green, JD x 2, and my troupe of yellow/white Cub Cadets. If I mix all those colours (spelling for Don T.) up in my mind, I come up with purple.

P.S. Hydro Harry: Where ever you've been for the several years I've been kicking around in this forum I feel the need to tell you that you HAVE been missed. Many times I've seen the statement "if Hydro Harry was here, he could answer that". My story and I'm sticking to it.

 

[hydroharry]

Allen S and Gary S - I don't think the fuel line rubbing the linkage on the Governor would stop the Governor spring from controlling the linkage but worth checking.

Allen S - have a look at the Governor spring in the 4th pic (one at the bottom) and then look at it in the other 3. Certainly looks like something put a BIG ole KINK in that should be the straight part of the spring. I can't understand that, and I can't see the connection at the Governor arm end of the spring.

Bruce Nolte - Memory Lane Thought - recommend you raise your skidders on that QA42A. I can't see no concrete, nor asphalt, nor stones, nor dirt on that driveway. Ooh, and one more thing - recommend you always engage the brake pedal lock before leaving the tractor. Even without the engine running, the QA42A in the down position, chains in place, these units will run away from ya (especially if they don't like the work you're doing).

Hydro Harry...10/4 on th kink in the spring, but thats a sharp bend in it, that doesn't happen by accident. Someone at sometime 'adjusted it' for some reason. That would put more tension on it and maybe keep it from throttling down more than keep it from powering up. <font size="-2">With respect, A in NJ</font>

 

[aschumacher]

Gee wizz, I didn't mean to kill input so early

...

 

[hydroharry]

Allen S - I agree the kink would "should" put more tension on the spring, but the way it looks in the pic, the spring is under no tension, which would be correct at idle. It's as if it's the wrong spring (to long). I believe I recall something about Kohler having 2 different lengths for these long springs, and maybe someone replaced it witht he one that was to long, and then did just what you're suggesting and kinked it to make it work properly.

There are alot of questions, and if's here, in my mind. I think we need a list of specific questions for Gary to answer before we can really track down the problem.

No. 1 Question for Gary - did you remove the double clamp holding the throttle and choke cables in place, when you moved your engine forward. If the answer is NO, then it's most likely not a throttle cable problem (unless Gary tilted the engine to some extreme that pulled on the cable such that it slide out of adjustment even with the clamp in place). If the answer is YES, then I suspect the cable is in a position such that at full throttle there is no tension on the Governor spring, in effect leaving the engine running at idle only, even slight tension would only put it slightly above idle, and cause the problems Gary describes.

If we assume the cable is positioned and operating correctly, and everything worked well (throttle linkage, governor spring, governor itself) before Gary slide the engine out of place, then my next question is:

No. 2 Question - Gary - do you have a double rubber rag joint at the point where the drive shaft connects to the rear? If you have the single rubber rag joint did you re-install the ball bearing that centers the drive shaft in the rear joint??? If not, then I leave it to others on here to confirm, but I'm thinking this may be just tearing up the joint and not really transfering the power to the hydro pump. Anyone care to comment on this possibility? Another possibility is the roll/spring pin at the rear connector may have fallen out or broke (if Gary reused it) and then the drive shaft may be just spinning inside the connector. Comments on this one.

I suppose by the time Gary gets back all of this will be resolved and forgotten and we'll have to start over. Oh well, still an interesting discussion if you all would like to comment.

I posted in the trailer section a small piece on bearing and what I have found from hauling trailers.I hope I did not cause any body to get annoyed with the method I use. I hate ez lube axles because people think they just have to pump a few pumps of grease in them every year and that is all that is needed. For tires I will still buy truck weight rated tires for my trailer as most trailer tires I found don`t last. There I`am done. Have a great day Don T

 

[hydroharry]

Don T - greeting to ya up there, north of the border. Know what ya mean on the grease and bearings. Should keep an old set around close to your air, so you can show people what NOT to do by spinning'n'm - gotta like that wirrin' noise tho, kinda neat. By the way - does each of your Cubs have a duty?

Donald - Measure yer Craftsman pulleys and blades fer Ryan in the Sandbox thread ... do something constructive for a change !

Frank - Put the hooch back in da jug befer they take away take away take away your Yankee green card !

HH - It took 2 or 3 days for us to get Gary to put his governor spring back to the factory holes setting.
Your way of setting the cable is different than mine. I push the governor arm open then put the throttle at WOT and hook it up then slide the cable to were it wants to be and lock it down. If it doesn't idle down enough then I slide the cable back a little.

 

[fcurrier]

OK, KEN!

 

[dfrisk]

Ahhh, something new being discusssed. I remember Dad & I at the IH dealer watching their head mechanic spinning ball bearings with compressed air and sailing them across the lot while on break. They were used bearings from a rearend of a BIG Farmall.

Hey Everyone!!!
I have a Cub Cadet 123 that doesn't run very well. I rebuilt the carb and put new points and coil on it. I have to crank it for quite a while to get it runnning but once it's running it's ok until you put a load on it or throttle it down. I'm gonna check the compression but i'm wondering what it should be? It's a K301 engine. Thanks Alot!!!

 

[kide]

Adam:
You won't get a reliable compression reading, as the K-301 has an automatic compression release that holds the exhaust valve partially open at low (cranking) RPM. If you want to check rings and valves, check into a leakdown tester...

You leave a lot of information for us to guess on.. Is it getting hot, does it smoke while running, why did you rebuild the carb, is it getting good spark, have you done a "static" timing adjustment, are you sure the fuel supply is good (and the gas is good) - all typical small engine troubleshooting.

I would go back through carb adjustments first, as it should idle down - you may still have a stoppage in the low speed circuit..

 

[aschmidgall]

Thanks Gerry! The whole story is that the mower sat for probably 10 years. Right off the bat i drained and flushed the tank, checked my lines, and corrected a no-spark. I pulled the fuel bowl and it was very dirty so i rebuilt my carb. It runs ALOT better now but still not quite right. You have to choke it like normal to get it started but after that, if you don't touch the throttle or keep it at around 1/4 choke, it'll run as long as you want. It smokes a little right on start-up but i assume thats normal and no smoke while running. I know my gas is good as it's the same for a few other mowers. I don't know how to check the timimg on this....

 

[kweaver]

Adam - If you have to run it with choke then it either still has a gas flow problem or air getting past the carb/block gasket.
