The throttle on my 4ac (ae82) is sticking. Its so bad it doesn't start sometimes until I pump the throttle enough that it frees up. There's quite a delay between me releasing the throttle and the revs dropping. Also when I clutch in to change gears it revs up about 300rpm before dropping again.

 

Ive cleaned out and around the carby. Ive also lubed all the throttle components around the carb. The throttle return spring works fine and doesn't feel like there's any delay.

 

I've got a weber and adapter plate I could put on but I'm not sure how hard it would be to hook up the accelerator cable, fuel line or what I'd do with the vac lines. Ive never used it in the months I've had it so I'm not even sure it works.

 

Anyway, any advice is appreciated :yes:

with the weber, ive got one in my ae71. it bolted on, I'm not sure if i to get a longer piece of fuel line or not.

 

i removed all the rubber lines/metal and just connected the line to the little copper pipe on the side and connect to the advance on the dizzy.

 

i modified the bracket for the throttle cable and the cable just connected straight up.

 

fiarly easy

Grrr well I went to the trouble of changing my carby (to another standard carby) and now its even WORSE. No idea how this could be. Its not the secondary sticking, though it does seem to be vacuum related as it only does it at times of increased vacuum. I can rev it happily and the revs will drop normally when the clutch is in. But if I clutch in after driving then the revs will jump and then stay almost constantly up there until slowly going back down to normal idle.

 

Anyone have any ideas?? :no2:

I've looked into this a while back and came up with 2 basic solutions

 

 

1. Webber conversion.

 

2. Take whole car down to carby rebuild place and walk away. Get them to ring you once they have it right.
