exhaust popping

Recommended Posts

2l pinto in escort with twin webers, recently started popping on accelerating(mostly at high speed), they r still running too high fuel pressure so im wondering if this is the only issue, thinking of trying "weber specialties" on north shore to tune them, any suggestions?

thanks

out which way?? , though the intake or exhaust???

over lean mixture can cause backfire out the intake , dont ask it work because i dont know , my 910 does it because the warm up circuit dont work as it should .
