HOOVER Posted May 26, 2011 Report Share Posted May 26, 2011 Maybe some information on what you have on your bike or what you did to have it "back together" Quote Link to comment Share on other sites More sharing options...
spurdy Posted May 26, 2011 Report Share Posted May 26, 2011 Could be a timing issue. Check the pick up gap and check your timing if you have an adjustable plate. Check to make sure the flywheel is mounted correctly and rotates without a wobble (bent crank). Back firing isn't a good thing, obviously, but it can damage your reed petals. Hard to start could also be timing but most likely fuel related. Too rich on the pilot, bad fuel, etc. SP Quote Link to comment Share on other sites More sharing options...
bansheelover22 Posted May 27, 2011 Author Report Share Posted May 27, 2011 (edited) well i took my fly wheel off it had a timing advance key in it with the hang over part towards the front of the engine and it looked like the flywheel had been moving on crank a little the key was a little loose in the key slot i think im going to put a stock key in it o and i mix my fuel at 32:1 with 93 octane and klotz super is that the right mix Edited May 27, 2011 by bansheelover22 Quote Link to comment Share on other sites More sharing options...

If I were gonna use one I would definatetly lap my flywheel into place. I prefer the timing plate for the adjustability of the timing.

1sick6 Posted June 6, 2011 Report Share Posted June 6, 2011 What kinda plugs are you using. This happened to me after a rebuild when I was using standard NGK type plugs then I just put some iridium plugs in and it's all good now, more then likely it's just the plug gap tho.
