I've got a 400F engine I installed into a 350F frame and trying to get it running in order to sell as a running 400F engine. The rest of the 350F is crap. Anyway, it doesn't have the starter motor so I'm having to kick it. When I try to kick start it, it won't fire up but will intermittently either attempt to start or backfire. Checked the timing, plugs, points don't arc when opened and closed so I assume the condensers are good. The carbs were recently rebuilt and at this point I assume there's enough fuel to at least make it start even if it runs poorly.
Any help appreciated.
