Ryobi flameout
 

I've got a ryobi 31cc engine mounted on an ultra easy stick. No cowl. The problem I'm having is the engine flames out after about 30 seconds of vertical at full throttle (actually anything above idle). Otherwise it runs perfectly.
I'm using a zinger 18-8 prop and 11mm walbro carb.
The end of my fuel tank is about 12" from the front of the carb, have 5/8" clearance carb to firewall, and have good tank venting.
I've tried running a little rich on the high end to where it occasionally 4 cyles, and reversed my pump cover to reposition the vent, but these didn't seem to make a difference.
I'd like to get this figured out because this setup at 12.5 lb hovers easily, but I have to do it high up in case the engine quits. Any ideas?

You pump in the carb is not woking. Take off the fuel line that you got going to your carb. hook it up to your fuel can and set it under you engine. That way the pump has to draw the fuel to the carb. have no fuel in your line. Hit the engine with your starter. If it will not bring up fuel to the carb. it is your pump in your carb. If it does bring up the fuel and the engine runs fine that way you have a prob with your tank.

You can have a fuel line on a gasser as long as you want it. The pump will bring the fuel to the carb it if is working.

If you pump is not working just go to a small gas engine shop and get a kit to rebild your carb. It is ezy to do.

I hope this helps you out.

I think the part number for the repair kit you want for a WA/WT carb is D10WAT assuming it's a walbro...
