PW50 ran, came home now it doesn't

[k5383]

I traded a kid some heads for his pw50, he brought it to me at work.

I put gas in it (mixed with oil 32% mixture)

Drove it around 10 minutes, one of our tech's messed with the carb, drove it some more.

Put it in the truck to come home, once I got home I have not been able to get it to start.


So far I have pulled the plug and cleaned it, it has good crisp blue spark.

Pulled the carb, inside was actually very clean.

Adjusted both screws on carb face, Not sure which is which but I adjusted them both to 1 and a 1/2 turns out.



Thanks!

Try a brand new plug, if that doesn't work turn the air screw in a half turn.

You need to know which is idle and which is mixture screw.The idle screw isn't set by counting the turns out, it is a wedge to hold the slide up a little.

Okay, I'm not sure which is which then.

I have adjusted the first screw, (philips closest to air intake tube from the filter) 1 1/2 turns out, and the flathead screw next to it also 1 1/2 turns out.

Genrally the slotted screw is the air screw, philips is idle.

The PW50 is and oil injection engine unless the system was disabled by a previous owner. So straight gas in the tank and lube in the oil tank.

Next a 32% mix would be REALLY REALLY too much oil! If it was 32:1 you'd be in the ball park which would allow the bike to actually ignite the mix.

Sounds like "the kid" wasn't the only one riding the short bus.
