I replaced the smashed-in-shipping factory airbox. (thought it had a flex-mount for a month or so:o. ("Duh-oh!" to quote one of my favorite TV personalitites ;)

I replaced the busted plastic airbox with a 90 degree elbow silver-brazed onto the carb. flange plate, and led a 1 1/4" i.d. hose up to a remotely mounted K&N under the gas tank, but the engine won't wind-up unless the choke is partially on.:confused:
I've tried with the hose and filter disconnected from the elbow...With the elbow left off and no filter at all, opening up the main jet, and the results have all been the same.

I can't walk far to due to youthful indiscretions involving brown likker and big inch V-twins, a horse wreck or two, and recently getting pin-wheeled out from under my hat while trying to walk across the street in Spokane.
I really NEED somend reliable trailbike that is easier to keep (hay will be $300 per ton by winter here:( ) and easier to crawl up on as well as not so far to fall off of than a pony;).

Kohler has NO tech assistance, and won't even sell parts to me.
It's a long ways to a town, and the shops there don't know what I am talking, about even if they WERE reccommended by the Kohler Kreeps from Wisconsin. (More wasted time & gas to get there.)

Anybody that can tell me where to get carb. tuning tips and and Mikuni butterfly (NOT slide type) carb parts?
I am getting desperate and would be glad of some real help.

Thanks!

If it ran well before, then I'd say you now have a vacuum leak. If it runs up only momentarily, then you may have a fuel supply restriction. You must take EXTREME care when testing this way, but while running it (idle is okay) if you spray around the intake manifold etc. with carb. cleaner, and the RPM changes, you have a vacuum leak. If you hit the muffler with the spray, you could be in the ICU!! If you talk nice to people at Kohler, they will often talk to consumers. I can't give you Service Dept. head's direct number, then he probably wouldn't talk to me! You probably won't be able to buy a Mikuni butterfly - Kohler offers few Mikuni repair parts, but you can look it up yourself at gardnerinc.com - on top click on "consumer," and then "parts look-up." Select Kohler, and put your spec number in. Partstree.com also has IPLs. If the butterfly isn't bent, why change it? When the airbox got hit, did the carb. bowl get dented? Also, look closely at the carb. - it may have a crack in on the mounting flange side.

P.S. I often get asked "why does it do (whatever it's doing)", when people neglect to tell me it didn't do "it" before they worked on it. Remember, if it didn't do "it" before, perhaps it lies in the last repair effort. Everyone goofs now and then - no exceptions : )
