Hey everyone, can i pick your brains for a sec..

Ive f**k the ignition timing and i dont have a timing light, cos ive just been making small manual adjustments, i had it perfect for a while and i dont remember where it went wrong, it was backfiring, so i retarded the timing. Then it had a very 'choppy' sounding exhaust note, so i've played with it and its better but its still choppy and lacking power, wont rev over 3k lol

So does it need advancing or retarding, if you can tell by the exhaust note being 'choppy'?

Thanks in advance

normally when I set by ear.. I wind it forward till the rev increase peaks and it starts sounding different, then I wind it back a few degrees from there.. but I've never tried an i6 like that.

buy a timing light.. even the cheapy ones will get you there and are about 20 bucks at supercrud.

thanks frankieh
