Our linkages are chosen by people who want a linkage that fits and works perfectly every time! Proper pivot axis provides extremely smooth and soft pedal response. The response is so good you will not know you have dual carbs on the car when our copyrighted instructions are followed. Provides full throttle every time, even on early cars. Our linkages feature built in adjustable return springs (springs should never be added to the carbs), adjustable side thrust at steel heims, ball joints at all ends and an aluminum center pivot with adjustable location for different pedal travel and quickness. Hooks up to the stock cable end at the stock carburetor fan housing hole (FI fan housings require a new hole be drilled).
Adjustments ensure full throttle and smooth operation. Three shaft bearings eliminate bending in the center of the shaft. An adjustable full throttle stop on the cross bar at the arm locations to limit pedal force against the carburetors shafts, prevents bending butterfly shafts. All require stock VW fan housings (or equivalent with coil bracket and fan mounting locations) and come with understandable copyrighted instructions. Chinese made 36hp fan shrouds hardly ever have fan mounting holes in the correct orientation. Originated in 1965. Made in USA by Gene Berg Enterprises SW 11#
Note: You may see Weber 40 or 44 IDA, 44 MX, or XE carbs advertised. There are no such models! All are IDF series Webers for Fiats.
