this isnt on my camaro but you guys are about the most knowledgeable people on these things i can find so hopefully you will help me. this carb is on my 1978 Bronco with a 300 I-6. i think i have the jets in it fairly close, atleast the primaries. the jets are .095. and the rods are .070x.037. it will idle fine and if you open the throttle at a medium pace it does fine. but if you just crack the throttle open(stay out of the secondaries tho) it just dies and falls on its face. i tired the next step richer jet and it got worse and i tired a step leaner and it stayed the same but had no power. im running the pink spring right now. what im thinking is that im to rich on my power side of the rod. would that make sence? or am i too lean? im new to playing with this carb so any ideas are helpful.

 

Is your Acc pump arm in the right hole?

 

was in the middle hole. moved it to the closest to the carb. got a bit better but still not great.

 

When you say "crack the throttle open" what do you mean exactly?

 

i mean like snaping the throttle open. just like with a flick of the wrist open then closed real quick like.

 

How is it if you floor it and leave it?

 

after moving the link of the Acc. pump it stumbles and sputters and USUALLY takes off. before moving it it would always die. still does maybe about 25-50% of the time if i hold it open. i am keeping it out of the secondaries too.

 

anyone with ideas?

 

Is this a new carb or a used one?

 

used. in good condition tho. was very well taken care of.

 

Use the stiffest springs, I had the same problem you have and I never got it perfect..

 

i already have the stiffest spring in there.
