I bought a 70 hp for my 1650 fishhawk. the Engine did not run or idle well and eventually would not run at all. No spark. I diagnosed a bad timer base and replaced it. Now I have spark on #1 and #2 but 3 is dead. I switched the #1 and #3 coils and plug wires but #3 is still dead telling me it is not the coil.
At this point I think I have a bad power pack or possibly a bad stator. I think the power pack controls the firing on the three cylinders and is my most likely the culprit.
The power pack OHMed out properly. The stator ohmed out at 735 on the Brown to Brown/Yellow and 410 OHMs from the Orange to Orange/Black. The trouble shooting guide from CDI says the stators OHM should be between 450 and 550 OHMS. I cannot measure DVA.
My question is can a bad stator cause just one cylinder to not fire while the others work or does this mode of failure point to the power pack.
