bad top end

[pro line]

Last trip to the dunes the shee wasent running right. Due to work I havent had a chance to look at it until recently. The problem is its top end is a dog and is missing bad. I don't think it a jetting problem because it does the same thing with my alky carbs and I have had both sets dialed in for a while now. I have checked the comperession and both sides are 165. I'm lost right now and any help would be great.

is your timing advanced? mine was missing and laying down on top when the timing was at 7-8 degrees. backed it to 4 degrees no more problems.

what type of fuel are you using?

Could be ignition... Have you had the flywheel off?? Make sure the pick-up coil on the flywheel is properely gapped @ about 18 to 25 thou.. or Have U messed with any of the ignition wiring?

The problem started before i sheared my key (+4) I now have a new one on. I havent checked the gap on my coil since i replcaed the key. I also havent messed with my ignition in years. I run both 110 octane and alky and had the same problem with both.

 

Thanks for the help guys I'll check that gap as soon as i can and if anyone else has any ideas im open for anyhting.
