Riddle Me This: Possible Timing Issue?
Backstory: some may remember this a few years ago.
2 years ago my stator rotor warped and shredded my stator. I took the engine out and replaced the rotor and stator.
I put the engine back in 1 year later. It would not start. It would only back fire occasionally. Front block was back firing out of the carb and the rear block was back firing out of the tail pipe. All plugs were sparking, all had gas on the plugs. After much research and cans of starting fuild it was dead to me. I feared the worst, that being something with the timing was messed up but wasnt sure how or where I went wrong. And dreaded the thought of pulling the engine out again.
This last week I decided to look at it again as now i have more time. I Graduated. So the battery was swapped with a new one. And after a few attempts with starting fuild and new fuel it started up and ran for about 5 minutes before I turned it off. It ran very well, wasn't back firing or anything.
Today, it would not start again. It did the following:
-Rolls over and over and over..
-Rear Block is back firing out the tail pipe
-Front block is pushing white exhaust out the tail pipe
-Front block is pushing air through the carb about every 3 turns (hiccuping).. and it just blew flames out of the carb... actually catch the bike on fire for a brief minute. That's when I stopped. I think it's sparking on the wrong cycle (when the intake valves are open), but for only one cylinder? I'm confused how it could have started and ran yesterday.
Am I looking at a timing issue, a coil issue or something else?
If it's a timing issue, the only thing that was moved was the front balancer gear and the stator rotor. I'm confident that they were lined up right. I'm puzzled about what else it could be.
Any help would be much appreciated.
