More info plugs wet?
Will it start if you put a little gas in each spark plug hole?

i put fuel both in the plug holes and splashed some into the carb not sure which one made it fire. like i said it only ran for a couple seconds plugs are a little wet could they be fouled? goin off your screen name your must know something or too about these motors

Have you done any thing to prime the fuel pump and carbs?
Try a rag in the filler and just a huff or two with a air gun
NOT TO MUCH DON"T SPLIT THE GAS TANK.

I've filled the inlet of the carb assuming the floats are working properly the bowl has fuel in it I'll try the priming deal see if I can get it to pump

It's pumping got it to fire again for a second by puttin fuel down the plug holes what kind of settings are there for these carbs I know nothing about 2 strokes

Standard idle and air screw 1 1/2 out to start and go from there.
did you pull the pilot jet and clean with torch tip cleaners
or a wire hair from a wire brush. Use the proper size screw driver to remove it

Where's the pilot jet located

DOOmsman · 01-22-2011, 05:00 PM

way up in the hole on the left.

The pilot jet emulsifies air and water to fuel the engine on start up, there are tiny holes that can not be cleaned with out removing it. this is a good picture.
