PJ vs PWK

u can see a big diffrence in the design from a pwk to pj....here is the 35mm pwk..just cant find a pic of a pj

The biggest diff visually is the PJ has an oval slide and the PWK has a D-slide, but both are still considered "flat slide" carbs. The PWK is a newer design and has more high-end flow and power. The PJ is better for low end. Both can be made to work with a little time and patience.

PWK is available in a wide range of size, 28-39, while the PJ comes in 34 and 36.

PWK for sure is better but a pj is very good also_Once tuned both carbs work great.I run both and I have no complaints about either one of them.
 
PJ carbs have been around since the 80s. They have been tried over and over again to be a proven carb. I run 34mm PJ carbs on both of my blasters and my brother runs one on his. If i had the cash I would upgrade to the PWK, but the PJ is a good choice. You can find used PJs on ebay for cheap......I would go with one any day over a stock carb.
