thanks for the suggestions,

compression is very strong- it has fouled two new cotter pins on the crankarm from my ambitious jump starting technique.

the new plug seemed to help a good bit. got it running consistently this afternoon. i fiddelled with the mixture screw and tried combinations of choking and not, with holding the throttle open and flicking as it caught. The best combo seemed to be flicking the throttle slightly with the choke open. problem is, even with the idle setting as low as it can be set, the carb draws too much fuel revving the engine too fast, and the idle mixture has little to no effect.

I'll check to see if the needle has a lower setting in the throttle slide, otherwise, perhaps a smaller jet is in order. I hoped that the kit would have been balanced for jet size, throat diameter, pipe and 70 cc jug, piston and head.

this is going to be a bit more tuning than i hoped for, for a little two stroke novelty item (already have too many motor toys- moped/scooters- das puch, NQ50 spree, Yamaha Razz, a motorcycle- Honda cbr1100xx, and four wheeled toys- porsche turbo, and toyota fj40)

next weekend- install the new brake pads and larger front cog and try it on the road. yikes is it loud, annoyingly so, to this middleaged set of ears... ;-)
