trx 90 help

i have a 94 trx 90 i just had a bunch of head work done to it. new intake valve, cleaned re-surfaced new seals valve jobs . it is now bored .75 over all honda parts. my thing is that it will idel but you cant give it any gas it will cut off. it will fire right up but to give it any gas you have to hold it wide open and it just stutters. rappiled press the throtel and it will rev but that is the only way.
HELP PLEAS. i have had the timming and valves checked and re checked

if it sat for long clean the carb and check the jetting!

Sounds like carb

when you got all that work done did you replace the stock jets with larger jets? sounds like your not getting enough fuel.

cam was wore out new cam and runs like a champ
