Timing? Done static.....cam chain maybe? The end of the screw is a bit nubby

Battery not charging? Lights burning brightly?

Did you test that number 4 is actually producing a spark? Maybe the plug wire has an issue.

Tank vent clog, petcock clog, rubber manifold air leak.

You will have to pull the petcock to look at it. Tank vent should be straight forward if it is clogged.

Get a can of WD40 and spray it at the manifolds while idling. If they RPM changes you have an air leak.

#4 looks lean, but 2&3 look to be close to carbon fouled?

#1 and #4 and #3 had about 30 minutes of 12k ohm cap. 3 was last. I swapped w some other coils w new caps. Test tomorrow

skamagedon · « **Reply #13 on:** August 07, 2012, 03:48:51 PM »

So. New/different coils. New plug caps. Gas in all bowls. Rubber booties good. Tappets reset. Timing is an issue. I can't get the light to go out either way I turn the plate. 1st mark on 1.4 side lined up to timing mark. Visible tiny gap between points leg and cam.

#4 won't fire steady. Colder pipe. The rest are the same temp

Set the gap first, with the point "leg" on the highest point on the cam, then rotate the motor to the timing position to set the timing.
