Re: 2v pinging

Try timing the spark by ear. Retard spark till pinging goes away, (under acceleration). Timing marks on Clevos arn't always correct, mine are out.

Don't time it be ear!!! Thats just bodgy and can end in teara if you combo aint right, and if the clevo timng marks are out, FIX IT.
You have initial timing to deal with as well as total timing and if someone thinks they can guess these two evens by ear, they won't be near my high powered Cleveland.
