Initial Carb Set Up

Post by Alkana » Fri Feb 10, 2017 7:33 pm

Hi Folks

I wanted to know if there's a matrix chart of some sort so as to help me set up my new dual EMPI 40 HPMX carbs on my 1972 Super Beetle. The engine is a 1641.

I am usually operating it from 3,000 to 7,000 feet elevation and at times I head to the beaches in Southern California.

I heard the carbs should be ok out of the box, but not sure what to expect.

Any help would be appreciated.

Thanks, Michael

Suggested jetting for Weber 40IDF's, mains, 1.30, air, 2.00, idle, .50, pump, .50. The Empi is a clone of the Weber so this would be a good starting point only. The higher elevation might need slightly bigger idles and mains
