Just a thought..........................that reminds me of the problems I had which we all discussed on an earlier thread 28/11/2011 or thereabouts. My problem started with the rear bearing cage breaking up and scoring the cylinder and piston very badly. I also found that the fuel system would not pressurize at all and in fact the engine would tick over very briefly but quit as soon as I began to throttle up. I eventually found the brass crankcase bushing had rotated a small amount, enough to completely block off the crank case to regulator vent hole and hence no pressure. Just a bit of a guess here, but if you attach a length of fuel pipe to the crankcase pressure nipple and place the other end in a small container of fuel and then spin the engine over with an electric starter you should see air bubbles in the container of fuel?. If not the crankcase is obviously not producing any pressure and fuel will not flow in sufficient quantity to run properly. Obviously the fuel line(s) and one way valve needs to be checked and properly working in place first. <div>
