I put a tm33 board to sx600 redhead engine and have started the jetting. I notice that i have to jet up seriously. even there was stock sx700 jetting inside.
now have 52,5 pilot and 2turns. clip position 3. and main jets are 143 141 141 if i remember correctly. 1 size leaner than sx700, because it has been driven in the summer.

And still my mtx-l shows 16 afr to wot on garage when back of the sled is lifted.
I now thats not a correct way, but the snow is not a lot of and water is a semi-frozen.
half throttle it seems to show 12,5
and idle 14,2

did i really have to still jet up, and how much. Tomorrow i test the one size bigger aboard and look. or if can I find the bigger jets, then them.

If somebody have tested tm33 to 600. I really want to know.
