Re: Strange detonation problem

Did this problem come on suddenly? Did you make any changes before it started?

Carbon buildup happens over time, so you should have noticed the pinging just a little at first, and it would go away with just a slight change in throttle opening.

If this had a sudden onset, I would suspect failure of some component, like a broken advance spring, piece of dirt in the carb, vacuum hose falling off . . .

Re: Strange detonation problem

It came on slowly. I noticed it a little and retarded my timing appropriately and it did fine but now I dont want to go any lower than 4 degrees btdc. I will try the techron and see what happens. Also Ive just become the owner of a Holley 350 that I cant wait to try out!

Ill keep this one updated.
