Hi, the title describes my problem. I've kind of concluded that it is a fuel problem, so I've changed tank and all fuel lines between tank and carburetors. No fuel leaks.
I have the VRO-pump, and have just ordered a standard fuel pump. There seems to be a fitting for this on the port side behind the starter. There is 3 threaded holes, the middle hole has a bolt with a gasket in it. I guess this is the pressure/vacuum source for the standard pump?
When I remove the VRO-pump, can I use this bolt to plug the pulse-line hole after removing the plastic fitting that is connected to the engine? Or should I leave the pulse line hose and plug it?
Also, when i plugged the oil side of the VRO-pump, I realised that it was water instead of oil. I pumped out about 0.5 litres of water before any oil came from the tank. I then removed the oiltank, and tried running on premix. The engine smokes a lot more, but sounds better with 2% oil instead of 2% water, but it still stalls after about half a minute on idle.
Question is, is it possible that water in the carburetors (from the oil tank) is causing the stall, instead of a faulty VRO-pump? Will the water be flushed out when running the engine, or do I need to drain the carburetors?
