    I am getting spark while cranking. Motor still doesn't run with dry plugs and the injectors off. I have tried initial timing everywhere from 8btdc to 4atdc. The most I get is a backfire or so. I was careful to make sure my timing marks were aligned while assembling the motor. I turned the motor over by hand and also clayed the chambers. If I had missed my timing this should have shown up then? I have this cam installed 4 degrees advanced, but it should still start. The duration is advertised at 280/290 and 214/224 (0.050). I am using the 2.02/1.60 valve combo. Could the combination of long duration and oversize valves be throwing me off or am I becoming nearsighted in frustration?
