pacemaker Ign.

[riverrat1]

I have a Pacemaker Ign. on a converted 470 one side is not hardly firing at all , seems to be firing good when I check plug wire to engine , changed plugs old plugs gap was .40 I only changed the one side that wasn't firing . after running for 30 min. I can grab one header pipe other two are a lot hotter , this is all just on right side as sitting on boat . Maybe Valves I'm thinking . But I'm just a old fart

Are you saying you have good spark on both sides when you check by grounding each plug to the block? Or does one side have spark and the other no spark?

good spark on both sides , compression on the both side is good the lowest is 110 psi
