Hi all,
I had my original mufflers/resonators and exhaust pipe replaced with
2" pipe, a flex coupler, a glass pack, a resonator and a new header. My
car was running fine with the old stuff. Now the car backfires terribly
on deceleration. I have not found any intake or exhaust leaks. I am
running Solex carburetors with 135 main, 185 main air, and 52.5 pilot
jets. Do I need to change the jets due to the less restrictive 2" pipe
and glass pack? I have also tried adjusting the air/fuel mixture
several times. The car smells like it is running very rich which I
never noticed with the old exhaust system. Any suggestions would be
greatly appreciated.
Regards,
David Cohen
