What do I have to do to clean the float needle seat on my Echo PB250 that has the same problem as others with gasoline filing the cylinder after shutoff causing it to lock up?
SOURCE: Proper gasoline and oil mix ratio.
My echo uses 50-1 ration. Home Depot sells the small containers for Echo Leaf Blowers that you mix with one gallon of gas.

sounds like a dirty carb, dissamble it and rinse good with carb clean, be careful when taking the top off it that you get it back together the same spray the white center good and all little holes good. then reassemble, also try to loosen your gas cap maybe first before cleaning carb, you might have a plugged vent in the line coming out of the tank. Good Luck

My research shows that a consumer gets a 5 year warranty and a commercial user gets a 2 year warranty on any Echo equipment they buy. Could you consider getting some warranty service on this unit since it is still under coverage? It sounds like a fuel delivery problem (carburetor adjustment maybe), but I also realize that some of the newer "rotary" type carburetors in use don't have the Low and High speed mixture adjusting screws like the old-style diaphragm carburetors that preceded them.

hi there
pauly 46 here sounds like tank breather and carby problems ?
have you checked that the muffler and ex port are not blocked ?
have you checked that the tank breather is working, and that the fuel pump diaphram is ok - no holes or damaged / stiff , and also that the metering diaphram and needle valve are ok and are not sticking open, or the lever setting is too high or the diaphram is just too stiff and holding the needle open
either way check tank breather and carby diaphrams , and needle valve and lever and the muffler and ex port for blockage
i assume compression and spark and timming and induction system are all ok
if its still hard to start and everything checks out as good might have a air leak
only way to know is to pressure and vac test crankcases
might pay to let your local shop do this because you need some special tools
but cover the basics 1st
cheers pauly46 hope it helps

I don't think the oil-gas ratio will cause that problem. Did you check to see if the fuel lines or fuel filter is clogged?
