Just what is wrong with the carburetor that it can't be repaired? Are you putting it together wrong or is it so dirty it you can't get it clean?
That would bring me to the next question, are you sure your problem is the carburetor?
I'm not 100% sure it is the carburetor. I have just started to play with these mowers. The LT 10 ran when I pickup it up.
It did not run well as the governor linkage only had the spring attached to the throttle cable linkage. There was no throttle
response, only the idle speed adjust set high. I purchased the correct parts with the help of this forum and It started the
first time I tried it, but would not stay running with fuel coming out the bottom of the bowl from a small hole. I purchased a
re-build kit and put almost all of the kit parts it. After that it ran very little with being very "rich" with fuel seeping from the
intake gasket at the block. Removed the carb. and replaced the needle set and adjusted float. now it just turns over and
huffs and buffs backfire etc.
