Hi, Im looking for some help fine tuning my PHGB 21. Its been a long ride so far, but I think im almost there.
Puch maxi, Metrakit 65, Techno Bullet
Needle #7 at the top clip
air speed screw 1.5 turns out
I had a hell of a time getting the bike rideable initially, the bike just bogged in the midrange. It wasnt until I went all the way down to my 78 main jet and the top most needle clip position that the bike was rideable. And most of the improvement came from the needle position. Now, the bike idles fine, midrange and top end are very strong but bogs in the low end. From a stop, it bogs and spits fuel until about 15mph and then goes great all the way to the top. Should I go smaller for the main jet? A different needle? Any help would be awesome.
