John,

I suggest that you post your question on the Sailnet.com Atomic 4 e-mail list.

When you do post the question, try to describe any/all other symptoms you have been experiencing?

Not a bad idea to do a compression test and record your readings.

First, perform a "dry" compression test on all four cylinders. (Make sure your throttle is open all the way.) Record readings.

Second, perform a "wet" compression test on all four. Inject a sqirt of oil into each cylinder (do this one at a time). Record readings.

Post the results on the Sailnet list along with any other symptoms you can think of.

Good Luck,
Steve Kaminsky
