Helping a buddy out on his engine. It is a 540 BBC with an 8-71 blower that is teflon stripped. It has an enderle bird catcher, Mallory magneto.
The motor was recently freshened up with new rings and bearings. We are fighting a misfire. Upon startup the number one cylinder started missing with raw fuel out of the exhaust. All of the other cylinders are firing normally. We checked compression and did a cylinder leakdown test. Everything tested fine and all cylinders are within 2 % of each other. We checked spark and timing, and all is good. As a precaution we put in new plugs and wires. Still can't get that cylinder to fire. The plug is wet and shows no evidence of firing at all.
I am a newbie when it comes to blown injected applications. None of the tune was changed after the motor was freshened up. Any ideas on what else to check?
