I need some help….i have a 90 fourtrax 2WD….i just got a replacement carb for it because i couldn’t get replacement #1 adjusted out correctly. Now this one won’t adjust out correctly but my bigger problem is it is leaking fuel from around the small primer valve and i cannot get it to stop. I think i have pretty much decided to sell the thing but I have got to get the leak stopped first before i can. any and all help is appreciated.
