Ive finally got my engine running, with 3a crank and rods, piper 285 cam, 35mm exhuast valves,3a throttle body and 16v metering unit. Im having problems setting it up, the c.o was very low-between 0.08-0.15, instead of between 1-2. Does the k-jet metering unit having a c.o adjuster screw? The haynes manual seems to think so, but mine doesn't Would the engine benefit from 16v fuel pressure regulator? How can i increase the fueling?? cheers
