New to Two-Strokes? Plane won't start? Just want to learn more about operating your engine? Keep reading!

 

The following articles were written by Mike Stratman. They have been in the back of the CPS catalogs for years and are currently listed on their website. Full credit to the articles goes to them. I take no responsibility for the information presented in the below attachments. I wanted to take the time to add them to our site in case they ever disappear off their website or someone is searching with a specific problem on this forum.

 

If your flying regularly behind a two-stroke I HIGHLY recommend taking the time to read all of these articles. They do a great job of separating the myth from fact. It took some time to put this together and hope it helps someone out at some point.
