I previously posted this issue some time ago without success, I'm at a loss & once again ask for advice to try and get motor running. Since I received this motor not running I checked out the part numbers of flywheel points cam etc. (all good). I should mention that I have installed a new carb kit, champion JC4 spark plugs, fuel pump, driver coil, points etc. put starting fluid down plug holes, set points to open on the cam set mark turn the key and motor doesn't attempt to fire, very occasionally backfires thru leg relief ports. When I check the position of #1 piston when points wear band is at the cam set position, piston is well past when points presumably fire which would suggest timing is way off. Not being as knowledgeable as I boat contributors any suggestions would be appreciated. Thank you.
