Dan510Wag Posted November 10, 2011 Author Report Share Posted November 10, 2011 Have you checked ignition timing? Stock L20B? sorry, yes its the stock L20b. havnt had time to look over everthing, but thats a great idea, thank you for you help Quote Link to comment
datzenmike Posted November 10, 2011 Report Share Posted November 10, 2011 Idle set too high? Vacuum advance not working... Suck on hose going to the vacuum advance, the rotor should turn clockwise and hold until released. Static timing too retarded. Quote Link to comment
Hardwyre Posted November 10, 2011 Report Share Posted November 10, 2011 Sounds like the vacuum advance isn't working, leaving it lighting off the fire towards the end of the cylinder action, resulting in it exploding into the exhaust pipes. How's the power feel? Sluggish at all? If it's not vacuum advance, then check the rest of your timing. Quote Link to comment
