Re: my clevo missfires when cold
Backfires through the exhaust I gather? If it is? Try a plug change. I had that same problem. I found what was causing it was the dizzy needed to be regraphed to suit my cam (it's graphed to suit a stocker/mild setup). Not enough initial advance was causing it to fuel up and foul plugs.
Replace plugs and make sure the timing set appropriately and go from there.
