Hello gents.
I have recently purchased a china PZ19 that I wanted to test on my CT70 88cc as an alternative to the Sheng wey PZ20 that came with it.
I found my sheng wey carb ran best with a #90 main jet in it.
I have disassembled this PZ19 and found no numbers on either of the jets. Using precision Pin gages I found the main jet to have a diameter of 0.029" which from a chart I found translates out to a #78.
Before I even bother strapping this thing on my bike I was just curious where the rough point is for 88cc kits with this carb. the 78 seems a bit light when I was using a 90 on the PZ20.
I know a few of you guys really like those PZ19s as an alternative to sheng wey so I figured I'd give it a try. hope they chime in.
