Why would a 2 cycle engine not start?

== == Basically, the problem is often that, the choke being left "on" continually prevents the engine from starting because there is too much gas for the air being provided. (The choke control reduces the air being provided to burn with gas). On warm days, a two-cycle engine does not need to be choked very much. The cooler it is, the longer you need to leave the choke on. You need to prime the engine by pushing in on the plastic dome that you can see gas in. That sends gasoline into the fuel line. Five pumps or so is all you need. Be sure that the cut-off switch is turned to "run". Put the choke lever into "choke on" position.

Pull the start cord twice. That normally provides a good gas/air mixture to the cylinder. If the engine starts, put the choke lever back into the "choke off" position after a few seconds, and let the engine warm up. If it starts to sputter, put the choke back on for a few seconds more.

If it doesn't start, put the choke lever back in the "choke off" position. (Yes, even if the engine does not start).

Continue to pull the starter cord several more times. then put the choke lever back to "choke on" if it still won't start and start the cycle again.
