What is this linkage?

branman1971 · 07-02-2013, 05:26 PM

On my 1990 Marathon there is linkage that attaches at the carb and runs forward to the coil area and then down to the right side of the engine. I connects near where the oil injection oil line connects to maybe a pump but I dont see how this linkage makes any adjustment to the engine when moved. Anyone know what I am talking about here? Thanks!

"...then down to the right side of the engine." That sounds a lot like the governor assembly but if you could provide a cell phone pic it would help... .

that has a rod attached to it from the throttle lever at the carb,it operates the oil pump. When its pushed forward it increases oil volume from the oil pump. I see the rod is missing, keep it pushed all the way forward until you can replace it, or remove the pump and premix you fuel and oil.

I premix my fuel now and removed the linkage. Guess I can remove the whole pump. Already pulled the oil tank. Thanks kersh.

And you will need to replace the banjo bolt on the inlet elbow with a 6mm screw or cut the oil pipe and block it with a screw and some mastic otherwise your engine will start to suck air.
