Thanks, Jeff. I threw that in here 'cause I was too lazy to use the SEARCH function. When I had more ambition I found this:

Matt,
Per Brian Millers Website:
The newest style head manufactured by Kohler is much like the previous one, but has the spark plug located directly over the exhaust valve. There are two reasons why Kohler did this:
It prevents cold-starting incoming raw fuel from fouling the spark plug.
It helps to produce more engine power and torque by retaining the majority of the combustion heat in one area.
Despite of their low compression, I believe that these are the best heads to pull with because they flow good and they have excellent heat retention. The compression ratios and mounting bolt lengths are the same as the previous head. By the way - these type of heads are still available from Kohler. They come on the Magnum engines, too.

Frank C.,
Research has shown that locating the spark plug in the hottest region of the combustion chamber is best for preventing irregular combustion (preignition or detonation) from occurring. After ignition, the flame front propigates into cooler areas of the chamber thereby greatly reducing the tendancy for detonation to occur. Hottest area in an L-head combustion chamber is right over the exhaust valve, hence the relocation of spark plug to this area in later engines.

Need some input on what's going on w/the charging system on my newly aq'd 125. The needle bounces back on forth constantly. Battery is new.
Time for a new VR or a S/G rehab??

Does anyone have a drawing or dimension to make the bracket for the amp gauge? I would like to add one to my CC 122 also, but just need a drawing to produce one from. I have a gauge from a donor unit already.

Thanks all for the amp location info. Looks pretty straight forward and may add one although it most certainly a knee knocker in that location. Maybe I'll get lucky and find one or if nothing else should be easy to fabricate. A big thanks also for the tire data - I think my Goodrich set is in very good shape so I'll probably go with those on the older O. I love this ole dude and only paid $100 for it (each one) and actually had a complete hitch, fenders, and snow blade (not the correct one unfortunately. The engines both look good and the oldest has a std piston while the other has no markings on the piston (not sure what that says about it if anything). The oldest has a decent white vinyl seat cushion but who knows where that thing came from. Engines (k161s) are definitely different as are a few other things. Anyway, just learning my around these things so please near with me. Have a great day!
Terry, here's what Mike is referring to. Note the reinforcing pieces welded into place to fix/prevent the frame from cracking in these locations.
DAVID KIRK and others,
What's your opinion of venting the valve cover (with your Billet plate option) into the air cleaner backing plate like the KT-17's?? Would keep the side of the engine leaner, burn the gasses or too much oils in the gasses? More Pro's/Con's?
Also have a sloppy govener liknage from the carb. Anyone have a good fix for that? Is there a wear bushing, or replace the govener arm?

I'm thinking of trying this stuff on the project tractor. WARNING VIDEO IS LOUD. http://www.youtube.com/watch?v=kt0affP9_9M

Frank c posted a picture of his new cover for the breather for his 169. I see there is no filter in the breather with the new cover ? I wonder is the filter not necessary ? I know on cars the vent from the valve cover would have a filter on it where it entered the air cleaner also a PCV valve . I don`t know it the reason was to remove any oil from entering the breather and wonder if on a small engine if it would be needed.

Kraig - thank you soooo much for the pics! See clearly where the bolts are and will go ahead with the reinforcement whether it needs it or not. Gonna crack one apart later today (making room to work this am) so will report back. My wife (boss) is gonna try and help me with posting pics "when she has time".

There were tie-on seat pads available across the IH parts counter. One was white with a "pebble grain" surface like a football or basketball surface, and later a yellow and white one with a smooth surface, that looked similar to these. Both of thse are reproductions.

DT,
You are correct, this is no filter. My guess the small tube isn't big enough to let in much "stuff".
I'm thinking that if you were to vent it into the air cleaned (like a PCV valve) it may actually draw out and gasses in the crankcase and keep all the "stuff" from sticking onto the side of the block. My concern is it may produce too much oily gasses for the Ol' One Lunger to handle. I don't know??
Terry, I dropped of a 86-169 grill and a QL air cleaner cover this afternoon. Will keep you posted.

But you would have to add the line from the breather to the inside of the air filter on a Cub . I would think that as the air filter go dirty that would create a vacuum on the breather line . would that draw oil mist from the crank case .

Tom, keep in mind that you use a fuel line to route the breather gasses down and out below the frame.
