i have a puch polini kit with a 15mm bing.
the thing blasted for quite some time and am still in the middle of breaking it in. probably 200 miles on it.
i took the kit off, put it on an engine with a aftermarket crank and case matched it.
when i kick over my moped, it doesn't want to start. you can hear the engine pop like it's about to start up but wont ever completely run. it just pops every 10 seconds of pedaling and i'm not sure what the problem is.
it isn't a fuel delivery issue. banjo is clean and it's getting fuel and spark.
what could be my problem? timing? condenser? something? what am i doing wrong?
