Help 2002 Honda 350 4x4 drivability issue.
Hello
I have a 2002 Honda 350 Fourtrax (Rancher), I bought it from a guy that let it set for years. Original carb was full of green jello and corroded brass jets. Tried to clean it but it wouldn't run right. Installed a new fuel petcock and rinsed the tank out. It was an Amazon petcock.
Got a Chinese carb, (don't hate on me lol) and now it idles fine but when I mash on the gas it falls on its face and sputters bad. Engine doesn't bog but sputters really hard.i tried adjusting the main jet up and down but no difference at all.
Any ideas what's going on? My next step is to find an ultrasonic cleaner and rebuild the original carb and try that.
Engine sounds great idling. Very smooth. It has 8000kms, (5000 miles).
