Bought this fourtrax new, and has been awesome. The wheeler sat for a couple years, and so I had to refresh things to get it running again. Cleaned out the fuel tank, and rebuilt the carb. It ran for a short period of time, but started to run crappy, not able to get off idle very well.
I fiddled with it a bunch, and decided to buy a new carb. Found an aftermarket one, bolted it up, and it basically did the same thing. Ran ok for a short period of time, but then wouldn’t leave idle, and eventually not start (within a couple days).
I was frustrated with the aftermarket carb, so I found an oem carb, and installed that. Same deal. Ran ok, then craps out. I was able to get it to start with a little push of the primer, but nothing now. Won’t start anymore.
I’ve adjusted the idle screw on each carb. I still have each carb. The fourtrax is bone stock.
I have not checked spark, but replaced the plug. I’ll test spark soon.
Other thought is to test compression.
Wanted to put it out there and ask if anyone else had some ideas to get it running?
