My 1970 811 S has a chronically high idle at about 1200. My mechanic advised that there is an adjustment fork in the mfi pump (area) that lowers the idle. He say that he cannot get the fork to adjust and therefore cannot achieve a regular idle. We also believe that a fair amount of gas getting dumped into the oil. Is the gas going into the oil a concern?

Any thoughts and/or can anyone explain this if it makes sense.

A million thanks,

John
