I am working on a bayliner for a friend. small block chevy, carbureted engines turns over but will not start. distributor was rusted and replaced with an automotive HEI unit. before I started working on it. engine ran 3 years ago last time it was used. compression is 100 to 125 psi on all cylinders , wet with oil compression comes up to 140 . engine has been setting a long time in the weather. I rocked the harmonic balancer back and forth and watched the dist rotor, not much play in the timing chain so I dont think cam timing is an issue. it is a standard rotation engine, so I assume the firing order is standard gm 1-8-4-3-6-5-7-2 ? spark plugs wires dist cap and rotor are new, though they are not marine parts. I verified spark at the plugs. played with the ignition timing, but doesn't even try to fire. I connected the power wire of the HEI direct to battery and verified the dist has a good ground.
there is fuel at the carb and accelerator pump , tried starting fluid as well. still will not fire, not even back fire . I opened the gap of a spark plug to about 3/8 of an inch, spark will jump the gap but is not the bright blue spark I am used to seeing. seems it would be enough voltage to fire under compression. what am I missing? somthing I am overlooking? , my next step is to replace the distributor with a know good unit, just have to find one.
