Jeff,
How does the prime in step 7 function if the injectors are not turned on until step 8?
Thanks,
Steve Boese

My injectors are all the same size. When I disable the secondary, I think it works as it should. It is when I disable the primary that I am concerned about. I haven¡¯t tried enriching the mixture as Ed suggested. I will try that next time I run the engine to see if that is a factor. What is the best/most popular engine run up check to do with our rotary engines before take off? Does anybody have a check list that they would like to share?? Bill B |
