If your positive its not fuel, spark or timing then its either not getting air (doubt it) or a loss of compression. Might i ask how you know it isnt fuel or timing?

The fuel pump works, and i just put a fuel filter on it. I can also put fuel down the caborator and it will backfire and some times it will acctually catch fire. I took the cover off the motor to see the timing chain and the timing chain is tight as could be. if you try really hard you can wiggle it maybe 1/8 to 1/4 inch.

Suddenly.

it's pretty much a yard truck right now. it's got 2 or 3 minor holes in the frame so it just gets used for yard work. I'd like to get it on the road one day but i don't think it we ever get there. but we need it for a plow truck and it don't run.

my dad wanted it moved so we put gas in it because it has a pin whole in the fuel line so we don't keep much gas in it. and we put gas down the carb and it fired up and ran but it ran rough so he took it down the driveway and it just died. so we pushed it out of the driveway and worked on it for about an hour and just left it. i dragged it up the driveway with my dads truck and pulled the cover off the motor and the timing chain looked good and was tight. we messed with the distributor but did nothing.

ever thought it might be the fuel pump relay?, also have you checked your fuel pump?... when you put the truck in the "on" postion (not starting the vehicle)... do you hear the buzzing sound from your fuel pump?... also it might be your fuel rail or injectors not giving out proper fuel to the engine

every thing for fuel system works. we even tried putting fuel down the carb which takes the fuel right to the cylinder. it's still don't run.

What are those

Both of those will cause low engine vacuum if they go bad.

I think it is the timing some how. I can move the plug wires on the rotor one turn and it will try to run. unlike when it is were it is supposed to be it turns over and will backfire and fire at the wrong time. so i do believe it is the timing.

Try to dial it in with the distributor. Hopefully it didnt jimp a tooth on the chain/belt

Usually there is a bolt that your can loosen to rotate the distributor to time it. I havent had much experiance with these engines so idk exactly how or what the spec is.
