Not really. But it is possible that you have too large a shot coming out.

Try backing the nut off a turn.

 

One question for you. Does it start to squirt IMMEDATELY when the throttle is moved? And does it shoot out of both legs of the nzzle?

 

I immediately get a squirt from both ends...

 

This thread is spot on with the exact same problem I am having. I was about to e-mail carl about it and boom, here it is!

 

Maybe this has stumped even the Gods of Gas, the Fellowship of Fuel, the Engineers of Injection, the Politicians of Petroleum, the Jokers of Juice ...

 

Anyone solve something along these lines? I am having the same off idle hesitation. I have checked all of the above and can’t seem to work it out.. going to try spark plugs next but I feel like it’s a reach. My ap, is strong and pushing a good amount of fuel when I hit the pedal. Thinking it’s maybe rich, but I’ve tried 100 different mixtures with no luck

 

Maybe it is volume as Sterling said, not mix.
