Success with the HPMX?

Post by justrhines »

Howdy all,

In the process of tuning dual EMPI HPMX carbs I've installed on my '75 Spider with a stock 1756 motor. Was wondering if anyone has had success with a dual HPMX setup- currently running into some issues with major bogging down (to the point of stalling) on rapid acceleration. I'm hoping it's a jetting/acc. pump issue- hopefully someone out there can verify. :D

Thanks,
Justin
