I did it MY WAY  Group: Members Posts: 1,337 Joined: 14-September 04 From: Simi Valley, CA Member No.: 2,757 Region Association: Southern California  |
I've got a 1.7 block, warmed up to a 2.0 with dual weber carbs. The carbs were jetted per Aircooled.Net specs, and they were just rebuilt by a reputable local carb shop.
When I accelerate, I get absolutely no power. I've replaced the distributor, coil, gas lines, gas pump and made sure the carbs are synchronized. Car idles like a champ. I can stomp on the gas and it revs up nicely. As soon as I put load to it (i.e. let off the clutch), the car bogs down and sputters. Any thoughts/ideas? |

Dirty idle jets.
broken/torn accel pump gasket. From what I remember (a blatant disclaimer) the main jet does nothing till 2500-3k rpms...something like that...the point being, off the line, you are using the idle jet...and again (memory) there is an additional fuel squirter that shoot fuel in at the top of the venturi...just for take off need...so you get a little extra squirt to go from 0-10 mph... Look and check the ignition...then look down the carbs (in the venturi) make sure each barrel is squirting the extra fuel... If the accel gasket os torn, the carbs will still sync up at idle... If you get stuck...test the carbs at 3000 rpms.. Or ignition. Rich |
