I've put in a low mileage PX200E engine (so Buzz tole me) that I bought from Buzzsolomoto a couple of years ago. This engine is autolube, but has gone into a non autolube vespa. Put the engine in a few weeks ago and changed carb and box to non autolube and blanked off the oil tube with a paper gasket. So the new type 24/24E non autolube carb (ie with the hole plugged up to the left of the idle jet) has a 55/160 idle jet, main tube is BE3 - 160 and 118MJ.
The engine fires up with choke and have to keep choke on for quite a while. But after that, its slow and erratic to pick up revs, with the occasional backfire and slow to come down, normally this slow to come down would suggest its lean. In fact, I don't think you could ride it with the revs being so unpredictable.
I've checked resistances on stator and they are within limits, put a previously tried CD unit on, fully earthed and a BE8 plug. Not yet checked timing, can't imagine that its out but its on my list.
I'm not usually beaten with 2 stroke engines (mainly lambrettas), but wondering if I have missed anything changing auto lube stuff, as all that is new to me.
Thanks
