I have an 0s140rx ,i keep it for 3 month not running it . Last weekend took out

my 2m pattern plane to fly , when i start the engine the fule keep spliting out from the caburater !!

From idle to full trouttle, what went wrong !![] it seems like the pump is pymping too much pressure

on it ! What went wrong !!

Before i store the engine , it run perfactly .... no probleum at all !!

Any advice.... please .

You will need to check the fuel system very thoroughly. It's possible that the pump system has some solidified fuel residue that's not allowing it to regulate properly. You may need to run a few liters of fuel through the pump to dissolve any fuel residues. You should be able to get the engine to run at full throttle. Even if it's not regulating properly, full-throttle operation is possible. Just start the engine at a high throttle setting. You will be able to adjust the full-throttle mixture. Let the engine run for several liters of fuel, and work with the throttle to see if the engine will start to regulate again. If not, you may need to purchase a new pump/regulator.
