Predator gap

[Wicked]

How do check the gap on the coil if you do not have a gauge

Buy a Gauge.
Or the average credit card is .030 and a standard sheet of paper is .003

For a stock flywheel we always used a regular buisness card. For an ARC flywheel, we just used a buisness card and credit card put together, or just a credit card, depending on which flywheel it is. Im speaking of adjustments at the track or somewhere where you dont have access to feeler guages or calipers. You can pick up a set of feeler guages at the local auto parts store for less than $10, which will give you the guages needed to set coil gap and valve lash both. Valve lash does need to be checked and adjusted also

Dont guess, do it right. Go to an auto parts store or Wal-Mart and buy a feeler gage set.
