Just wondering: could the starter not be spinning the engine quickly enough? Didn't think too much about this because the impulse couplings should allow slower speeds like hand propping. Starter doesn't turn too slow, but it's not not at 200 rpm. 60 rpm? just guessing on that count.
Thanks for the suggestions;
UPDATE: our son was visiting tinight and, when he left, I decided to pull the prop thru in search of a spark. #1 cylinder did not spark when timing marks aligned and impulse coupling popped. BUT #4 DID generate a pretty good spark. Strong spark.
I thought the wire harness could only be installed in one orientation. Could I be 90 degrees off? Firing order is 1-3-2-4 so 4 is 90 off from 1.
