I have just bought a brand new Zenoah ZP 26Ei engine with electronic ignition, this is the first Zenoah I've had and seem to be a bit stumped. I thought I would assemble it to see how much space it would take in the cowl of my model, I fitted the exhaust and plug and tried to fit the plug cap...... well it seems no matter how I try it won't go on. The plug is supplied with the engine and is a Champion Y82, looking at the cap on the electronic ignition i doesn't even look like it would fit. Has anybody had any dealings with these engines and the plug/cap mismatch? or am I a complete numpty?..........
