I've been having problems with my 85 gsl and getting the power with acceleration. Its got a 650 dp and I've ran through the carb in and out and can't seen to find the problem. Its running 72 primary jets and 80 secondary. I've got msd 6al to the leading with great spark on all for plugs but i can't seem to find the issue. Any help is greatly appreciated.

 

gonna need more info,what is the total timing set at,is the distributor locked,holleys don't just run good on a rotary,they need work to get them to work decent.also what is the exhaust set up ?

 

The timing is fully advanced. When i called racing beat, they told me how they build their Holleys they drill their jets and the high speed air bleeds. I don't agree with the drilling of the jets but to compensate for the drilled high speed air bleeds, i pulled the cap off of my progressive vacuum port to trouble shoot and it seemed to gain more high end power

 

Exhaust is racing beat headers and racing best exhaust, no cat. However, i do have a small exhaust leak I'm having fixed Monday

 

Put a 48 mm ida Webber on it then it will realy go ,plus don't run more than 15 deg advance and have 7 deg split all ways works the best
