MC1of80 Posted January 18 Share Posted January 18 Hi Rich. What is done to the engine? 8 degrees is way too low. Usually 10-14 initial with about 29-34 at 2500 rpm is a good starting point. Each engine has a "sweet" spot with timing that it likes. 3 Quote Link to comment Share on other sites More sharing options...

Steve G Posted January 19 Share Posted January 19 Try 15° and go from there. I went through the same thing on my 402 trying to set it at 8-10° and it wasn’t going to happen. It’s happy at 16 Quote Link to comment Share on other sites More sharing options...
