If your saying it cranks good but won't start, try some starter fluid in the intake. I usually open the choke valve, spray a little in there. Stand back away from the vehicle, have helper crank, see if it helps? How long since a tune-up?
There is always a safety issue with using a flamable spray, safety is your responsibility.
Also, with an extended crank, you can remove airhorn from carb without removing carb, depending on the carb, see if any gas in the float bowl. Do you see any gas squirt in the throttle-bore, when you work the throttle-linkage?
Please consider a to help us answer more questions.
