Dont be a wimp ,do it like a real man ...Grab hold of that spark plug wire and crank it over, You will know beyond a doubt if it is firing or not But make sure someone is videoing it first
I was able to get the oil drive gear to fit by very gently filing the whole. And got it to work and run. Apparently usually they send heavier springs with the distributor for different applications which I did need but did not come in the box. My video is as complete as can be for a project that took me 5 months.
But make sure someone is videoing it first
