i just bought a TRX 2.5R engine and i broke it in a about a week ago and it ran fine for a few days. after i broke it in i tuned it just a lil bit and it was doing fine up until about 2 days ago. it just started running like crap. ive been trieing to tune it but it dont even wanna idle anymore and no matter what i do it wont run right. i tried reseting the carb and going from there but nothing i do seems to make it run correctly. if anyone can help id really appreciate it.
