is your M1 the spread bore? i'm running a t-quad on my warm 360 and have the pri jets drilled to .101 and have the piston set up at just one turn off bottom, make sure its bottomed and you note exactly when it starts to come up. also make sure you have the right piston spring on the rods, it should be about 1.5" tall and the spring dia should be .023. i have seen other springs that are not correct. i'm running without a choke and related hardware.
