I have a wolverine 350 that I got and it came with an fmf mega max, new stator, and a new carb and it just doesn’t seem to have the power it should and will only get to 20 mph, I sent it to a local shop where it sat for 6 months and I went to pick it up and I got it back in pieces, so I said I might as well do some minor upgrades when I put it back together and so I got some new piston rings order a nice, full engine rebuild gasket kits and new head bolts, etc... so I did all of that have it together and it still won’t run right, starts and idles nice but doesn’t have any top end power, there are no tears in the intake boot and it was re jetted for the fmf when it was in the shop, the guy that was working on it checked my valve clearances and measured out my timing chain to see if it was stretched.
