My wheeler has an odd problem. It started off as while riding it would randomly just shut off immediately like turning off the key or removing spark. Ater it sit for a bit, it would start back up and run for a couple minutes or up to fifteen minutes or more. Then it got to where it would only start and idle, when attempt to give throttle it would just die. Now it doesn't start at all. It seems to have all the requirements to run: fuel, oxygen, spark, timing, compression. Things I have checked, tested, or replaced:
Timing is good
New carb and fuel pump
New stator, coil, spark plug, plug boot - has good spark
New cam and rockers (rockers set to .006)
Compression 90 psi
Checked all wiring
New battery
If anyone has any ideas or suggestions, they would be greatly appreciated. I'm at wits end with this thing.
