Im trying to get my 45" running, but cant get it to fire on both cylinders. I have a new coil, sparkplugs and a new battery, breakers and condenser is new from a chevy. It fires on the front cylinder and momentarely on the rear. I have had it running a couple of years ago with a mag so i know it has run well before.
If i remove the rear plug and starts the engine (running on front cylinder only) it seems to have spark all the time. When run with bouth plugs in, the rear is very wet and the front is black when i remove them. The valves and tappets have clearence, so they should close as they should.
This thing drives me insane. Feels like i have tested everything, seting ignition, checking carb, changing battery etc. Seems like i have both spark and fuel in the cylinder but it wont fire right.
What can it be causing this? Can it be something with the coil even if it fires? Can it have something to do with the chevy breakers and coils?
Had thoughts about an intake leek before, but for a while i had it running right (about 10 min) so i excluded that thought then.
Please anybody have any idees what it can be causing this?
