Luther - that pic of the Kohler block puts a knot in my gut. Hey thanks for checking your condensers too. Don't know that we'll ever know what was original but nice to see the Delco Remy version.

Neil - the advice on the Forum you followed, was that for static timing the engine???. I'm no wizz on the internal components, but if the timing is right, and the internals are installed correctly, then I lean in the same direction that Tom H was suggesting. Getting fuel to the float bowl is good to know - but next you need to make sure you're getting fuel thru the carb. If you have the air cleaner cover off and the choke off, you should actually be able to look straight thru the carb and see the fuel spraying into the intake as you're attempting to start it. If you don't see the fuel (and it will be a spray) then I think you've got a blockage in the carb. Another method to verify this is by disconnecting the spark plug wire from the spark plug, put the choke on full and try to start it 4 or 5 times (wait about 15-20 secs between attempts to let the starter cool down). Then pull the spark plug. If it's not all wet with fuel then you're not getting fuel thru the carb into the intake.

Art - thanks for posting your data on the 169's and 1650's. I'm very surprised to see a 13 fin 1650 listed with a 1976 build date. I thought the 13fins went away alot earlier than that. You've convinced me that a 169 could come out of production with either a 12 or 13. With regard to the info from Paul that Harold provided, about all production being stopped and only 169's were being built from mid to late 1974, is still a possibility. What we need it build month info for other xx8/xx9 tractors to see if any show up as being built in Sep/Oct/Nov. Maybe the guys on here can provide build month/year for models other than the 169s. I have this gut feeling that we aren't going to see any in these months except 169's.

Bill J - what happened to ya??? Are you working on the 1650???

Norm B - what physically happens when you tow a Hydro that's been sitting awhile - well it depends on how far you tow it. If you only move it about 3 feet, then the flat spots on the bottoms of the tires from sitting, will probably be on the top of the tires. (Sorry I had to thro in a joke here). I believe generally that if the hydro relief valves are released when you tow then you are turning all the gears in rearend. If the valves are not released then you are not only turning all the gears but also forcing the hydro fluid thru the pump. Even with the valves released I think some fluid does still flow. Hopefully someone else on here can confirm this, and maybe even elaborate.
