OS .61 Hanno
I have an OS .61 Hanno that I just replaced the piston and sleave so I don't want to throw it away. The motor is leaking fuel out of the back of the pump through the hole in the adjustment screw on the pump. At times fuel pours out this hole, sometimes just a trickle, and occasionally no leak. Any idea what causes this and what can be done to fix it?
Can the pump be rebuilt?
Are individual parts available?
Is the entire pump available?
