you should be able to use a Timing Light while cranking to see your crank pulley.. mark TDC on it somewhere.. that's how I do this type of angle/crank timing setting stuff especially if It doesn't start first try. I blew the starter off the bottom of an engine once, and took a tooth off the flywheel. Now I check timing... much easier to fix.

it cranks and fires, but doesn't stay more than millisecond.....

any help please.........

Can you post a log? It may need more fuel just after starting to keep running

Went to fire mine up tonight, and it will crank and Fire, then die. Then my battery must be to small and cranked it dead so tomorrow I'll get a second battery tied together. I did get a few attempts in tho and crank, fires and dies. I see in ts that it syncs up with no issues at all. But I'm thinking I might try wasted cop tomorrow if sequential only fires and dies

Got mine to fire today. Won't run in sequential mode, only semi fuel and wasted cop. Must be a poll level phase or crank tooth look up that is wrong
