I have a pre 82 delco distributor in a 140 merc. that I just upgraded to the mallory electronic ignition.
I bought the chrome mallory can coil that was suuposed to eliminate the need for the external ballast resistor.
The install was easy and very straight forward..... but now the engine runs like crap. It starts good but then after running
for a few seconds the engine starts spitting and sputtering and then finally starts running slower and slower and getting
rougher and rougher until it pops out the carb and dies. After that it's really hard to get started again. Almost like it's running out of electric. Put the points back in and everything is good again.

Any help would be good. I'm planning on calling mallory today so I'll keep everyone posted just in case someone else has had this problem.

Thanks
Gary

Welcome to iboats.

I suspect this is an I/O motor??? If not let us know and the mods will move it back to outboards. I am moving it to the I/O forum.
