Thread: Detonation!

Tweet

I am having some difficulties with my Nova detonating after I shut it off. I noticed this problem and have began putting 93 octane in it. I am still having the same problem. It is driving me nuts! Any suggestions would be very appreciated.

That's dieseling, try lowering your idle speed a bit. Oh, well, pull the air filter and make sure your choke is moving correctly and it's not caught up on something or perhaps a little gunked up.

Alright thanks BRT. Will try that.

I forgot to mention, but I doubt it is the problem, is that if you're overheating, it might cause similiar issues although higher octane gas like you've been using should counteract that. Let us know!
