Hello All,
I have a saito .72 mounted inverted on a on a Aresti Arf.
I put a sullivan tank in. The center line of the tank is pretty close to the center of the spray bar. I have an OS "f" type plug installed. The engine was broken in with about a gallon of 15%fuel.
The engine runs at full throttle. When I bring it down to about 1/4
throttle, the engines RPM's will start to "pulse" or become erratic.
When I was braking in the engine it did not seem to have the problem.(The engine was up right). Is there something special I need to do if the engine is inverted?
Would the low idle adjustment cause this? I did try to lean and richen it out, but the same thing. Anyone has any suggestions?
This is the first 4 stroke Ive owned and its not a pleasent experience.
Please help!
Thanks
