Troubleshooting a no spark issue, was running OK, maybe a little rich, turned it off, now no spark. I've checked/ohmed out the main key switch, the start/stop switch, neutral switch, brake switch - all good. It will crank the starter, but no spark with the starter or when I try the pull start. I've checked all fuses and diodes. Swapped battery. New plug. New coil. Swapped in a used CDI - no help. Traced, removed, cleaned, reattached all grounds. Removed things like my winch from the circuits to be sure a bad relay or something was dragging it down. When testing voltages, the orange wire going from the CDI to the ignition coil shows no/very low voltage-shouldn't it have 12V on it? Sometimes I get a very weak, intermittent glow on my spark tester, but not enough to fire the plug. I've checked continuity on just about all wires in the harness. Checked/cleaned/lubed w dielectric grease- all connections, redid a few that looked old/dirty. I've checked the stator resistances, all good, but have a stator and rectifier ordered anyway, will arrive Sunday. I verified that the rectifier has a voltage output back to charge the battery while cranking - 10.5-11V, low, but expected while starter is engaged. What else can I check as part of troubleshooting? I have a Haines service manual, but the 1999 350 4x4 seems to be an odd model, there isn't an exact electrical diagram for it, but found one for another year that has all the same number of wires and same color wires, so I've referenced that. Any hints, tips or advice would be appreciated! Thanks!

I been working on this thing for like 2 months now and it will not run right, is very smokey, and has a pretty loud tap that i think is in the bottom end. Not sure how much the parts are but i will put the time into it if they are pretty cheap. Im not very experienced but going off how the plug looks and the oil on top of the piston i am getting a whole lot of oil coming in from somewhere, not sure if it can come from the valves or if the rings are just shot, my cheap scope cant really see the walls of the cylinder too well.

I've been using Valvolene 10w 40 ATV oil but, it's like $8.00 a quart. Is that about the going rate? Or is there cheaper alternatives that would be suitable? Thanks

I recently was gifted a 1998 Lakota 300 and it was modified to start only by electric start. ( Removed the pull start) So I put together all the parts he was able to find and I believe it's back together like it's supposed to be but when I start it via electric start, it turns over but I do not hear the sound a proper combustion sound makes. Furthermore, I did all the spark tests and it's showing none whatsoever.
I installed a new starter and I believe I installed it correctly. Could I have accidentally thrown the timing off? I lined up the timing marks but the top mark will NOT line up correctly.
