I have a 2003 wolverine that had a gummed up carb earlier this summer. I took it off and cleaned it. The pilot jet was clogged and caused it to not idle. I put it back together and did an oil change with new plug. Now it idles great. The problem now is when I start to drive it at higher rpms it starts to putter. It never stalls. I've verified the float level. Could it be air/fuel mixture screw?

Thanks

would it be the main jet that is attached to the throttle cable that needs the clip moved up or down? if it runs good to 3/4 throttle then starts to act up, it could be that ... maybe someone else can jump in with more carb experience.

If your carb is one that has a diaphragm on the top check to make sure the carb diaphragm/s have no holes or pin holes in them. And many times once a carb sits up with gas in them the needle valve and seat tend to corrode and causes it to not function properly. If you haven't cleaned out the fuel tank I would suggest doing that and if the fuel line has no inline fuel filter I would also add one of those as well.

      2023 Hisun Axis 700 fuel problem
      By ButchM
      Hisun 700 EFI. Replaced TMAP sensor had broken off . Fuel pump pressure 41psi. The only way I can keep it running (and runs fine) is to close off fuel return line.

      By dkgg5755
      This thing came with a cheap aftermarket carb on it the problem I'm having is it won't start with choke installed into carburetor it will start and get run without it installed then bogs out after about 2 min run time I've checked timing , compression, checked valves for proper clearance , also did a smoke test for air leaks found none.

      2006 LT-F400F stator/generator cover change: What is the best way to check that all is good with the transfer operation before reassembling?
      By middlebrookgt
      I have replaced the cracked stator cover on my non-running 2006 LT-F400F that I purchased recently, checked all the shafts vs the service manual and pics and advice here.  I replaced missing gears, bushings and washers, made sure that truth marks were all aligned properly, that the shift cam springs felt like they returned properly, etc.  IAfter installing the new stator cover I checked the transfer lever for proper movement from L-H-R and then cranked it up.  Happily, it runs and changes gears well in L,  but it will not shift into H or R for anything.  I have opened it back up and am going back through it looking for the missing puzzle piece(s) but how can I best check that I have everything right this time before buttoning it back up?

      Change 2000 TRX250 Top End to 2007 Type?
      By C2INS
      Does anyone know if they're interchangeable?  I have a 2002 TRX20TE and 2007 TRX250TE, so getting to a set of common engine parts would be ideal.

      Suzuki king quad 300 idles great but Boggs when you apply throttle
      By 97kingquad
      Okay so I bought this 1997 sazuki king quad from a guy and he had it for a few years. 
      He had it registered and on the trails last year but he said it bogged and backfired when he would try to drive it. so it sat for a year. 
      I bought it for 800 bucks and got it running that night and it ran great for a few days 
      But I parked it the other night and went to start it again and it was really hard to fire up and when I did it was bogging and idling high then low again.
      So I took the carb out and cleaned it (ended up doing it twice because it was still doing the same thing) 
      Now today I have it running slightly better, but it is still like 20% 
      I have been looking it up and trying to figure it out but I can't find the issue, has anyone else had this problem? I'll attach a video of it running and giving some throttle
