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.
