cam timing-compression or exhaust stoke

I am currently in the making of adjusting my valves via waiting for postal, did you get a chance to check the clearances?

Yeah, All within >005-.015mm specs . Still don't know why it's running so weak. Ran it around the block just too much vibration and not enough guts.

Might be running on just two cylinders. Would perform spray-water test on headers.

Ignition timing might be stuck in idle position.
Would assure weighted arms are freely moving on pivots.

Good Fortune!

not sure if you have cvc carbs but I have had stuck slides in the past.

the intake cam mark and the exhaust cam mark should be 44 chain pins apart and on opposite sides from each other. correct me if I am wrong patton I have a small 4.

Want to thank everyone for their input on my top end rebuild project. Finally got the problem fixed. The primary coil wire on #2&#3 coil open connection. Thanks for the heads up Patton on the spray water test on the headers. Best choice I've made by replacing seals ,gaskets,re-shim and remove old carbon from top end. Runs like a new one!
