Title: Interesting Kohler Build Info
Post by: mowdak1 on October 30, 2007, 12:19:38 pm
Was searching the web for other goodies and stumbled upon this page detailing build specs for Kohler engines for garden tractor pulling; thought some of you guys might find it of interest since the topic of Kohler builds surfaces on occasion around here.

The page appears to contain a LOT of great information on Kohler engine builds, along with a good many Kohler engine specs! Worthy enough, I felt it should be stickied here at the top of the Kohler build section anyhow, so I did!

I also have a puller tractor to go with the racer I'm building and I have found a ton of good info for modding my Kohler on that site..

My KOhler in my puller is a VERY stepped on K181 with carb work I learned at Brain Millers site...

Most Kohler valves can be set to 0.010" intake and 0.012-0.014" ex. depending if you are mowing grass or pulling with it.

Unless the valves were ground down on the stems then the overall length of your valves should not have changed.

are you talking carb bowl?? that could be a fuel shutoff like the briggs has, you can take it off or you have to apply 12 volts to it to allow fuel flow through the carb,
Title: Re: Interesting Kohler Build Info
Post by: crapsmen on March 30, 2009, 07:17:14 pm
ok thanks. yes in the carb bowl i was wondering if it went though a reasestor and lowared the voltage or if it ran the 12 v. but i will try and hook it straight to my battery and so if that fixes it but thank u ver much

It's an "Anti-After fire solenoid", and yeah you can just plug the hole, it doesn't need to be there.

Or take it out and cut the plunger off.

Solder a jam nut inside the bowl, would make a handy drain.

Ok, that was a bad idea..I removed it. Sorry
