Depends on what needle you intended to run. I have played around with one for a short time, but never got it quite where I would like it. Maybe in the near future I will get back to it. A few people talk highly of this carb but I have yet to see any jets/needle that would get me close. Extremely rich down low. If you are running a new one from sudco, don’t bother with the DDJ needle. You are better off using the stock needle out of your stock carb. (Still not ideal, in my opinion).
