Jim;
I ran a set of Weber 34's on my 1.7,ran great,milage was even better,( high 30's),it would run 90 mph all day. BUT above 50 it couldn't get out of it's own way, I.E. if you were to pass another car or truck you better have a mile or two to wind it up. Scarry sometimes! Please get a set of Weber 40's or a comparable set of carbs. You will be happer in the end. OR keep the F.I. MY 2 cents Dave
