HELP!! 92 Bayou 300 Not starting


I have replaced the Ignition coil, CDI box and have what I think is a good spark. I have rebuilt the carb and it appears fine but my quad will not start. I place my finger over the spark plug hole and i appear to have compression.

Any ideas?


1. Run a compression test. Anything less that 100 pis is weak and may not start.

2. If above 100 psi above, pour a small amount of fuel in spark plug hole, install spark plug and try to start. If it pops off and dies, you have a fuel issue, If it doesn't, you have a spark and/or timing issue.

Thanks...I will pick up a gage this weekend and check it out. I will post back the results

Thanks again
