Thread: Motor want start?

You take a big risk with starting fluid on a two stroke. If your motor is larger hp and 4 stroke a short burst thru the air intake should be ok.

Before doing that check your compression and make sure it's good. Then check your spark. If those are good then suspect a gas problem. I would stay away from starting fluid. Stand a good chance of damaging your motor.

Thanks guys. I'm not going to do it, I'll tinker with it(90hp 2 stroke) a little more this week. I just hate taking it to the shop because it will be 3 to 4 weeks.

Also check your kill switch

Thanks guys. Somebody told me today to spray seafoam in the carb. I don't know.

...and verify the shifter is in neutral.

Another trick with 2 strokes (used to use in snow machines). Take the plugs out, verify spark. Before inserting the plugs, take a small cap full of fuel (about the size of a 20oz soda bottle top) and pour it down in the cylinder. Put the plugs back in finger tight, connect the lines, and hit the switch. She should fire right up and run for a second off from the gas in the cylinder. Many of these machines were a "suction" feed system and often times this small amount of fuel would allow them to pickup fuel from the tank. Same holds true for smaller engines without primer bulbs.

IF it does fire and die, I would say you have a fuel issue. Check to ensure you don't have a filter plugged someplace. IF it doesn't fire, more than likely it is an electrical issue. A spark test may also confirm this. Like others have said, Neutral, kill switch, could be the culprit. Those two above things should point you in the right direction.
