Hi everyone
First I want to thank everyone on this board, it has been a tremendous help in fixing the Keeway Hurricane I'm trying to make roadworthy. (it now runs but could be better)
Ok, so the thing sat for a year and a half, and wouldnt start, so I cleaned the carb inside out, tightened the cylinder head
However, I didn't know jack about jets, so after cleaning the carb I just screwed in the main and pilot jets. Needless to say, for a while it didnt start up at all.
So after fiddling with the jets and float height it now starts and runs, but lacks some power when going up hills (will kind of stutter (too rich?), and have to accelerate very slowly for it to climb hills)
Anyways, my main question was, on this pz19jb carb, the service manual states the float height should be 13mm.
From what I've read, the height is measured from the gasket surface to the very top of the float. However, even when pressed all the way against the bottom of the bowl, the top of the float is way more than 13mm.
So I take it the 13 mm is measured at the "line" on the floater??
See the picture, it is not the same carb but you can see that line I'm talking about (it is the same kind of float on mine).
At this point my jets are that much screwed in:
Pilot - 1\2 turn out
Main - 1\2 out and a tad more out
Does that sound like it makes sense?
Like I said, it runs ok but will sometimes lack power when going up a small hill (and that gets worse with 2 people on it).
Does lack of power = bit too rich so need to screw in the main jet a tad more?
Thanks a lot, sorry my post is so long.
