I have a Super Stick 60 with a O.S. Max .65 LA engine. When I take all is good until about 3 min into the flight. After about 2 min it starts to spudder like it wants to kill. I land and check it out and I notice that I have a lot of bubble coming from the line that comes from the tank to the neddle valve. I've change the lines and still get the same results. I am at the point where I want to just change the engine out. Any help will be appericated.
does the 65 LA have the remote high end needlevale just like the 61 FX ? its possiable if your seeing the bubbles come from the vavle to the Carb " clear small line maybe 2 inch " that the vavle houseing is sucking air , and the air isn't come from the fuel tank pick up line .
one thing do you have a known good fule tank that you can use for testing on a stand statickly ? it might narrow it down
just a Idea
if that doesnt work there is always electric
