Also you said in your earlier post that the engine cuts out after 3-4 seconds when you do the pinch test. just a few questions
how much did the revs pick up first and how close to the carb did you pinch it

When I was using the Go carb every turn that I would exit would leave a puff of smoke like a mushroom cloud.
Now I have the OS VG carb it is an improvement, but not as much as I would have hoped for.
Pinch was done 1 inch from carb, picked up fairly quick then cut out not quite instant but almost.
How do I get rid of the metal pinch? Run 30% nitro with 8% oil straight synthetic?
