Thanks for the suggestions.
Testing is still happening. We want the engine to work!!!!!!
Smaller tanks, mounted as high as possible, have been used for quite some time. This does seem to solve the starving. On May 14th we had the EVO with the high tank not starving and a new Silver pilot with stock tank at stock position, starving. That is our answer to the starving problem.
We were 110% confident in the AMA/NMPRA testing when we voted in November to accept the EVO into Silver.
I am the Chair/Coordinator of the C40 Rules committee, not a voting member, unless there is a tie. Our finest/best people are still working on this .
But we do not have the answer.
Fact is we have never specified a prop for Silver. If that is found to be the solution, we probably will.
