My 107 adventures
 

Finally got the 107 going enough to start a thread. It's a 1971 with 42" deck and snow thrower. Had to get a mule drive and deck hanger from a local dealers bone yard. While I was there I got a new hydro filter, backplate gaskey, battery and deck belts. Got the hydro fluid drained , housing cleaned and new fluid added. Also replaced muffler and changed engine oil. I need to adjust brakes too.

Being that it's 46 yrs I an having some issues lol. But I did get the yard mowed.

I think my main issue is with timing and /or the points. They will glaze ove after 20 min or so. I will be ordering a points saver ignition from kirk engines. I have some other small things already on order. It does seem to start easy however.

Also, it has been running HOT. After cleaning out a mouse nest I thought it would fix it but no. There is plenty of airflow from the fan. When I was done mowing you could hear the gas cap venting and it sounded like the fuel was on the verge of boiling. Maybe this is related to the timing? I am also having a hard time getting the muffler clamp to seal at the elbow.

I am a novice with this type of engine. The first thing I will do is read up on checking and adjusting the engine timing. I will need new tire but want to make sure it's running correctly before dropping that kind of money into it. Also will replace front wheel bearing then.

I have always wanted an older garden tractor and am quite happy to finally have one. The hydro works well and it drives surpsingly good considering all the steering stop. The hot running thing does have me concerned however.

Here's a couple pics. I will update more as the week goes on. Thanks!

I have a 105 that is having the same issues you are having; that being the gas tank gets hot, and if low the gas will start to boil. Scary !:crap: : What I discovered was the clamp holding the muffler is NOT tight enough and the exhaust is partially escaping under the hood, hence a very hot gas tank.
Problem fixed by tighting the muffler bolts.

New points and condenser, spark plug, head gasket. Rebuild carb. Set timing. Adjust valves. Make sure there are no mouse nests under the engine tins. Pull them and the blower housing and give it good cleaning. Change the oil.

It not running well then running hot is indicative (to me) that the timing is off.

Yeah something sure isn't right. I'm definitely going to change the points and condenser. Any tips on timing? I've changed engine oil, air filter, plug and wire. Also have a carb kit if need be.

I assume the cover next to the carb is for access to the valve springs? I gotta look up how to check and adjust them. Thanks

It's also a crankcase breather. It only goes back together one way. Download the Kohler manual.

Ok thanks. I got the manual downloaded and will be picking up points and condenser today.

You can time the engine statically or dynamically.

Thanks! I got the new condenser and points installed and adjusted. It's like a different tractor now. Still need some fine carb adjustments. I want to use up the older gas in the tank and then I'll get ethanol free. But I ran it for 30mins and got some lawn mowed. No issues besides being a tad rich i think. There were NO overheating issues like before.

My next steps are tightening the steering and a new seat and/or cover. Then I'll work on tires and cosmetics here and there. I'll keep on updating with pics and progress.

Whats the best way to recover the seat? The pan seems to be good still so I was hoping to find just new foam and vinyl.

I would assume if I got a generic seat some brackets might have to be made for it bolt onto the springs.

Going to run it some more tonight, hopefully it works as good as last night.

Thanks
