Norm,

Did you change the carby as well or is this the same carby as from the previous motor which would not go either. Not the old stuck needle valve issue? Crook fuel in the tank?

This reminds of the time I was helping a mate with a ute. Original motor was completely shot so fitted new rings and bearings. No go lots of smoke. Blamed out of round bores etc. Fitted a S/H complete engine that was a "good runner". Exactly the same result. Changed carbies a few times to no avail. Turned out the owner had filled the tank with diesel and was blissfully unaware that he had. Drained tank and refilled with petrol. Started first time and ran perfectly.

All this took about 3 months. The smoke should have told us something as should the fact that it was making oil in the sump. Ute still runs well 10 yrs later. We put that down to experience,

All the best
Jeff
