My mate Dunc called round today. So into the workshop we disappeared. Between us, we finally worked out where and how the connecting rod fitted. From throttle butterfly to governor arm. There is a very light spring over this particular rod. Unfortunately one end is broken off. Something to replace at a later date.
The engine didn't want to start. Not even a cough. So with Dunc squirting petrol into the carb and me operating the pull start, we got it going. But the only way to keep it going, was to keep squirting petrol in. Evidently not lifting fuel from the tank.
After Dunc had left, I decided to take the carb off. Only three little cross head screws hold it on. Simples! Nope! Those three screws had been in there for forty years most likely. One did unscrew, but the other two needed assistance. From a small pair off mole grips for one. Mole grips, a small chisel and hammer for the other. I think three new screws will be on the things for the future list.
I found with the carb off, the filter at the bottom of the fuel pickup pipe was covered with a film of dried dirt. This came of easily with a light brushing with a sued shoe brush. I was a bit leary of removing the tube completely, but I could blow down it and also the shorter tube next to it. That I assume is a return pipe.
With everything back together, I tried running the engine again. Sorry to say the result was the same. Tomorrow when I get thrown out, so swmbo can get things ready for the Christmas Eve invasion of the tribe, I will have a look at the diaphragm.
