I got the car to start but idle and Rev it will not do very well. Barrel valve adjustment seems like it does nothing. Then if you try to throw a Rev it slowly climbs the rpms.
I don't have a clue what to do. Any ideas?

Is the system flowed? Is it plumbed correctly? What spring pressure is your idle bypass set at?

Don't know your details that Paul brought up but mine for straight methanol was 28% +\-BV leak, 130+\- main jet with 2 psi idle bypass on a 6.08 gpm pump at 4000 rpm, throttle plates at .003 Hilborn 2 7/16" on a 467 inch BBC.

Mines a 468 .090 pill aside from that I don't know if seems like it's giving it way too much fuel.

Best advice I can give is send your pump, injectors and bypasses to Spud at Fuel Injection Enterprises and have it flowed and the tuneup will be very accurate, no guessing and no broken parts and it's very inexpensive.

Best advice you have gotten or will get.Same as above get it flowed regardless who.They will get you about dead on and can advise you after the sell. Compare cost of flowed system to cost of wasted fuel,wasted oil if milking it and any parts you could break along the way like flexplate from hard kick back. You will see where flow job is money ahead.
