Quadra 75 or 65 leaking fuel out the carb
 
I have a quadra I beleave its a 65 was told by the preson that sold it to me it was a 75 but it only has a 22-10 prop on it and will swing it at 6900rpms. so I think its a 65. anyway fuel is leaking out the carb at idle and up to all most 1/2 throttle. my plane looks like a it has a nitro motor on it from the mess it makes lol. anyone know what to do about this the motor its pretty new but an older motor less than 2 gallons ran through it. seems to run ok I did try to lean it out on the low end but then it would not run keep dying on me. right now it has good transition from mid to high throttle.

where can I find a manual for this motor

Possibly trash under the needle and seat in the metering valve of the carb

You have disassemble the carb on the steel cover side.

Pay extreme attention to exactly how everything is put together.

There is a rubber diaphragm
a pivot arm
a needle
and it's seat

It is probably best that you install a carb rebuild kit in the carb while you are at it. You can get one at a chainsaw dealer. take your carb in to him.

The chainsaw guy can fix the carb for you might be better for you?

What is the serial number of the engine?  What numbers are on the cylinder?
