Re: 66 MQ12A Over heat?

It runs! Not very well but it runs. Fuel pump is bad, real bad. I couldn't even get fuel through it with the primer ball. Carb float needle was stuck closed as well. I got around both issues pretty quick.

However.......

In retrospect I think I know why it was running so rough. It just occured to me as I was driving in this morning. I removed the fuel pump to inspect it when I could'nt get any fuel through it. I never plugged the pulse port when I tried running the motor. I hope I didn't damage anything.

ezeke, will a 9.9 fuel pump # 397839 work on this motor? The original fuel pump is long gone. The bad one that was on the motor looks nothing like the one in the manual.
