She's been coughing and spitting and been giving me greaf since I got her. Once I found 2 open holes, one on top of the carb and one on top of the intake and blocked them, I helped alot. Ive also ordered new intake to head gaskets. I found it was leaking after I sprayed some startgas around the seal. Hopefully that will make it run even better. Put all that aside, and have a new problem. Lately its been goin back and forth running on 1 or 2 cylinders. Couching and twitching like crazy. Ive been through 2 coils, different sparkplug wires, new sparkplugs etc. The strange thing is she always runs fine right after startup. And I can do about 10-15 kilometers before she starts actin up.. And if I turn the throttle all the way back once or twice and let her rip, she will start goin on 1 cyl much faster then if I ride her gentle.. One more thing, when running on 1 cylinder, the more throttle I give the more she start running back on 2. Not clean at all, and I have to shift down and get the revs up to force her running on both, but she does. Isnt this typically a problem with the EHC?
