Maybe one of you gentlemen can help me with this. I have a 61 AR that makes great power but will not idle any more. The diaphram is fine and internally the carb is clean. As soon as I throttle down, the engine dies within 15 seconds or so. The plug is fine [OS A3.A8] and I'm using Powermaster YS fuel.
Any thoughts ?
thanks
Check you pressure line to the tank. On one of my first installs of the YS 61 I put one of those spring clamps around the nipples of the fuel tank. I did this thinking it would help retain the fuel lines on the tank as this was a "pressurized" system. But after a few flights, the clamp cut into the fuel line allowing the pressure(and a little fuel) to leak. Just a possibility.
