Right little update, i replaced all fuel lines and filters rebuilt the lot in fact, yesterday went to the field and she started up first attempt no problem. I had also moved my earth lead off the alloy block as well so not entirly sure which one of the fixes it was but at least it was one of them.</p>

I had her in a good hover for a full tank no problem, but was finding a destinct lack of power on the trottle, guess i need to tweek the needlke valves to suit.</p>

Does anyone have any ideas how much and which way to lean or enrich the fuel to air to get optimum result please ?</p>
