You might change your water pump for starters. Test both spark plugs for spark, they had a very expensive solid state ignition and 2 small white coils which must never be disconnected while spinning the engine over. I used to solder those slide on connectors just for this reason. No way to test except by exchange. I've found good ohmn readings on bad coils so go figure. |

Well I had the lower unit off and the pump looks good I took the the screen out of the fuel pump and that looks good. Well I guess the coils are next. but 1st I going to take it out and mess with the jets I think someone messed with them and never reset them! |
