My engine is running great, except when under heavy load going uphill for an extended time.
*expansion chamber
*no base or head gaskets
*no porting
After going uphill for a while at full throttle the engine starts to bog and then die. I don't have an air leak.
After it quits, I can hear the engine continue to rev in a few short bursts like, "rvvvvvv.....rvvvvvvv.....rvvvvvw." Once it does that I can restart the engine and go again. It's like it is clearing itself.
I'm not sure if this indicated too little timing or too much? I just read that under load the timing increases (or needs to).
I pulled my plug but it has been used at different settings (ie. it's already colored). the tan ring around the center electrode insulator only goes about half way around on the side of the side electrode. There's some carbon build up on one side of the center electrode. If someone is really good at reading the plugs in detail I can post some pics.
I'm wondering if I need to put a base gasket back in, or if I just need to tune the pipe? Maybe lengthen the copper adjustment tube?
By having no bottom gasket that should be good for intake but bad for exhaust right? Instead of raising the exhaust it is = to lowering it a little. I'm stuck on this one.
