Rey - Start here. If you are concerned about a blown headgasket . . . the compression test will reveal that . . . also you can see water intrusion by reading the plugs. Water will steam clean them and they will look brand new. Honestly I think you just need to adjust the pickup timing so that it idles. One more question . . . do you have the giant 40 voltage regulator on your motor?

"pickup timing" I'll definitely be googling that as I don't know what that refers to. :) I don't know if I have the 40v regulator. Module wise I have the ~3"x5" black box located near the rear or the engine on the throttle linkage side and just above that on top of the engine there is a ~2"x3" module with 2 wires going to it. I'm still trying to locate a Clymers manual locally but if I can't ,then I guess eBay it is. Btw, I appreciate all the input I get on this...thanks so much!
