Ok, my shee has ran good most of this winter, I tried this new gas, and messed with the air screw a bit cause it was warmer, well it started missing in the topend. So I jetted up, and got a different gas, and some new plugs(B8ES). Now it will idle for a bit, but when you rev is misses real bad, wont reach the powerband or nothing. Its terrible. I have 340 mains in it right now, and 30 pilots. I'm starting to think its something with the electrical, not positive. Its impossible to do a plug check although I did let it run for about 5 min, revving periodically, I pulled the plug and it was spotless, a dab of oil on each bridge of the plug. Also, its spitting hella oil out of the pipes. Any ideas please, please, please post!

unhook your e-brake, sometimes the problem is with that.

what do you mean by 'this new gas' and 'a different gas'?? :confused: just the mix or what? if your stock, reset your air screws to 2 turns out and see if that helps. 340 mains seem pretty big, not knowing your mods though. list your mods and elevation.

I changed from c-12 to 110 leaded Clark gas. Ran shitty. Now I switched back, and also rejetted my carbs, and adjusted clutch. Since then its barely ran. There is a more active thread in the Repairs section of this site. Thanks guys.
