just did a rebuild on the transmission. engine ran great before rebuild. now when i start it i have too full choke it and once it start it goes in to full throttle and when you close the choke it dies out unless you give it gas
wide open throttle on start up

sounds like the carb slide was installed wrong, theres a pin on the kicker side inside the carb that has to align with the slot on the slide
you also have to be sure the needle is going down into the needle valve
or an airleak, did you leakdown test it ?

you have an air leak , you need to do a compression and leak test to help determine where it is . use the search function to learn how to pressure test the engine . My question for you is did you make ANY Intake or Exhaust Changes after the rebuild? If you did , what were they , and did you re-jet the carb for those changes?
gotta be vastly under jetted, clogged/dirty jets
or a massive airleak
clean the carb, disassemble and completely clean every jet and orifice.....................

then leakdown test it before ever even starting it again !!!!!......................

what size main jet is in there now ???
should be a 270-290 for that fmf
search for "plug chops" and learn how to do them
and leakdown test it, before it fries !!!
thats what it does when you have it full choke it runs fine for 5 sec but if you dont push in the choke it does that so yes
