Here is the deal... bought the 2003 LT 80 early November. It started no problem ran great. once it warmed up and you shut it off it was very tough to start again. once it started it would run fine. so early in Dec I was told that compression was a little low (was right at 100 psi) so rebuild time right.. took it all apart and put in a new piston, rings, you know the top end rebuild deal.. put in new reeds also... now compression is right at 110 psi and it starts when cold runs as long as you dont shut it off.. turn it off and try to restart can not get it to fire again.. doesn't even try to start. Let it sit an hour or so starts ------ My buddy JJ has an LT 80 that runs perfect starts right up all the time. we took the carb off his and put it on mine figuring it has carb trouble still same problem no different. We also swapped fuel tanks figuring pet c*ck. same problem.. so with his tank, pet c*ck and carb same problem... We put his LT 80 back together and his fires right up and runs great... We are both stumped. any help from you guys would be much appreciated... Thanks in advance... :blonde:
