M1 Single Plane Question

I put in a 50cc squirter on the primary side. We'll see after I run at the Mopar Nationals at Ennis, Tx in April. I had a 950 DP, and was told it was too big. So I put the 750 back on. It seems as if the 950 had more "seat of the pants" pull, but I will give the 750 another try. Thanks for the reply.
Yea, but what size are the shooters themselves? Have you played with the shooter size? I may be stating the obvious here, but if you increase the size of the pump, but use the same size of shooter, you are increasing the duration of pump shot, not the initial amount. Not sure if I am explaining this well. Get my drift?
