We finished installing the new motor yesterday. Engine cranks and really wants to run without spark plug caps on. The minute we put the spark plug caps on - nothing except a chunk sound (like the battery is really low). Battery is not - freshly fully charged off the charger. Took the spark plug caps off, pulled the plugs, not getting any spark on both of the spark plugs. No burning smell, no smoke.. just no power. Cleaned cables, double-checked, all are tight and connected. Although I'm not sure I trust my "grounding wire" which comes out of that box and connects additionally onto the negative connection on the battery. I had to redo that connection last season, and now it's bent up again..although it doesn't seem loose.
Here is what may be the mitigating factors:
When we pulled the engine apart to replace it, we found little springs stuck to the linside of the ittle hub inside the flywheel case. Not sure what those were or where they went. (Probably my problem - and has been bugging me)
On the case which encloses the flywheel, the connector that the electrical connection plugs into from the outside would push back inside the case (in fact it was pushed inside the case when we removed it). Nothing was broke and it was a pain to replace it (bought the new parts), so instead we left the old one and siliconed it in, not getting anything on any of the components around that area.. just enough to hold it in place.
Also inside that area, we sanded and cleaned the metal plates on the stator since they had oil on them. Don't think that would have ruined anything.
Before installing engine, we cleaned out the hull really good. Spark plug wires may have gotten wet, other connections may have gotten wet, but all the important boxes were sealed. We are now letting the wires dry out all day today in the sun just in case.
The flywheel was pretty chewed from the old starter. Replaced both. Replaced flywheel with a good used one - good teeth. Replaced starter with a Goki. Cleaned everything up really good. - Only thing was, we painted the flywheel... (hope that wouldn't do anything - since I did think it might at the time). Also new are the rotary valve, the rotary valve cover.
Also, before we replaced the engine, it had spark and was running fine before the ring on the piston broke and had to be shipped for warranty replacement.
I read something about fuses.. but if it were a fuse, would the engine be cranking over w/out the spark plug wires on? Any ideas on where to start with this one would be greatly appreciated.
