Ok I got a stock 02 660 the problem I’m having is it seems "flood" out, I think, when I cram my thumb into the gas. I can barely pull a wheelie. anything after 1/4 throttle is all fine power wise. I did just put on a nut buster intake on tonight but didn’t seem to change anything. I’ve got all the stock jets in, I’ve got the idle air at 2 1/2 turns out… When I pull choke it get worse.. What do I need to do to get that "efi" throttle response? Do I need to change jets, change needle placement, adjust air fuel screw?? Or am I just expecting too much out of my carbureted grizzly? I’m no expert on these carbs but cleaned and fixed a few carbs.. I’m gunna be doing a air filter mod with the clamp on style filter soon also (see signature to see what’s been done) I did clip 4 coils off the needle spring and did seem to help. Please someone chin in on this problem.
