well, it came with the 50cc pumps. Did run that way on a well made high compression low vacuum Signal 302 Mustang Motor. Mine is a new 6.1 HEMI with lower vacuum due to the new cam. So I will try it with the biggies and see if it is too much. Stepping down in the Primary side to 30cc. will use it this season for a bit drag racing. So ist Strip / street...
Do you think I can take over the Jet sizes from the vacuum carb for Initial start? carb size are both 750. But the DP is more a Performance carb 1000 years ago made by Blake carburation... i bet the carb went through 20 engine bays in his life... :)
