Can a J4 mag get oil into the points area from a bad seal somewhere. My Cub has been running poorly and when I took the cover off the points about a table spoon of oil came out. I think its from a leak I had in the oil filter gasket last year that sprayed oil all over the place but I'm not positive. I cleaned the whole area with solvent, filed and re-gapped the points and now I have no spark. Maybe the solvent wrecked the condenser or the wire to the condenser as I didn't remove it. Is the condenser different for a H4 vs a J4 mag and are they different from a distributor condenser. I have a condenser laying around but its probably from a distributor. I'm going to have to open it up tonight and have a look.
