Damn I’m glad I asked I set to 1 and 1/2 all abt must be wrong1 1/2 and 0 .
It’s a brand new carbIt could be the 3 small transition holes in the pilot circuit of the carbs. They have to be completely clean.
If you are at a dead idle then pin it wide open your going to get a hesitation, this is just how carbs work. The huge change in vacuum when the butterfly is pinned wide open takes a few seconds to start pulling fuel.
What u mean doesnt have trim? Vts? Yes they doAs above it’s a carbeurated ski. It will take a few seconds from idle to catch up. It sounds like you’ve got it running pretty good. Check those plugs from time to time. Also the fact that the GSI doesn’t have trim causes some delay out of the hole.
Yes as far as I know it’s a brand new carb for gs and other 720 motors cause they quit making gsi carb there junk there they same except the new one has the accelerator pump but I might need to fine tune low screw maybeDoes the carb have the correct jets, spring, needle and seat and high and low screws set correctly?
