Hi I got a 1984 8 hp John for $140. I knew it had a bad coil but it had 150 psi on both cylinders. It would barley try to start with a coil from my 1985 140 rude. I just rewired a connector to the push on verses the bolt on wire. I rebuilt the carb and the fuel pump and it started on the second pull in the barrell, idled and reved perfect. Changed foot lube after running a bit in the barrell and no water what so ever. Took it to the river and it ran fine, mostley at idle to mid but some top end due to the river level. When coming back, it started to die at wot like the key was turned off. It got worse the next 20 mins or so. at the ramp it would not even start. the ghas tank is brand new from wally world and is vented like a riding mower cap is vented and pumping the bulb had no effect. The 140 coil is old and rough looking. Im thinking it is now bad. the local shops have the OEM coil but they want almost $50 bucks. My questions are... What are the differences besides the wiring from 84 to 85 coils? Can I test the motor from a know good coil from th 85 140 without any damage? Am I dia. this problem wrong or could it be something else? Thanks for all yalls help. The 140 is running great from other questions posted on here!
