VoneSII Motor
I have a VoneSII and am having problems with the engine running rough at high revs. I have rebuilt the motor to ensure that there are no air leaks. It has a new glow plug.
When running at higher revs the motor surges and there is a lot of small air bubbles in the fuel line.
Does any one have any suggestions for what is wrong ??
Many thanks to all.
Nic.
