alright gang here is the deal. i just picked up a new to me toy. it has a 22r in it that ran when it was parked(so they say).the toy sat for about a year or so. if i pour some gas down the carb it starts right up and as long as i keep the idle over 1500 - 2000 rpm it will stay running. if the rpm drops it stalls and will not start again on its own..i drained out all the old gas and filled with new. replaced plugs , wires , cap , rotor , hooked up all vacuum lines except for 1 on the carb its on the left side front and its about a 1/4 inch diam. i took the 4 screwes out of the carb exposing the needle and seat , float , jets etc. cleaned everything and made sure all ports and jets were clear. and still nothing. i am stuck please help....oh and its a 85 if it matters..
