pump the throttle like you have a nervous twitch... the mikuni carbs are sensitive to sitting around for a while. the accelerator pump should deliver enough fuel to get it going.

Add a shot of "Sea-foam" to help out the old fuel. I started and ran mine, after they sat in a bone-yard in the desert for about 3 years. never did drain the old fuel. just added the seafoam and topped the tank off. never was a believer in "mechanic in a bottle" type products but, this one i will endorse.

i put sea foam in it and crank and cranked. i check the commpression with a gauge and two cyl. had 25psi and one had like 35psi. right now i have the plugs out and some pb plaster and marvel mystery oil in the cylinder. now somtime this week im going to try it again.
p.s. i just bought another mini truck same engine i think 1989 hi jet with 4 speed 4x4 put no dump box but till cool.

even if it had broken/stuck rings in all cylinders 25-35psi seems way too low. Pull off the valve cover and see if the cam is indeed moving when you crank it...sounds like you have valves stuck open in all 3 cylinders...I hope it isn't an interferance type head on that truck...are you sure the timing belt is moving when you crank it ?? good luck

i took off the timing cover and turn it over and everything turned.

must be stuck valves hopefully not stuck fully open .......maybe just carboned up enough to not fully close...MMO may free them up if thats the case..there must be open/unseated valves for compression to be that low..keep trhe progress reports coming
