Hi first thing what is the bike second thing is the engine a 2 stroke, if it is 2 stroke it most prob. has a reed valve, check that the carb needle valve is working as it should, then drain the cylinder and crank of fuel check the plug sparks, leave the carb off and put a small amount of petrol in it, try and start it if it fires once or twice, then it should start with the carb on it, if not there is a problem with the carb. good luck.
A reed valve in a 2 stroke engine is basically a way to prevent the fuel/air mixture from being blown back into the carb. If yours keep failing, the most likely reason is that you have bought cheap reeds. There should also be a reed valve support on the carb side. this is to stop the valve from vibrating and bending the wrong way.
If you get air movement out of the air cleaner and it only compresses air to 25psi, you have bent or broken reed valves in the head. Take the head off the cylinder and inspect the valve plates and reed valves. This is a Craftsman compressor so you'll most likely have to get parts through Sears at www.searspartsdirect.com. For best results replace everything between the head and cylinder; gaskets, valve plates and reed valves.
If you have a water drain knob for draining the crankcase (Kawasaki 2 stroke motor) ,pull the knob and drain the water. As long as you have not turned the motor over you are OK. Get the motor started and run it long enough to dry it out. If you filled the motor with water, turned it over and now it wont run, you probably have broken the reed valves. You will have to pull the carburetor, check the reed valves, and dry out the motor as quickly as possible. Be sure to fog the lower end as quickly as possible so the crank bearings and piston needle bearings do not rust. Replace the broken reeds, put the carb back on, and you should be back in business.
As I understand it, your air compressor motor runs but you can not build pressure. Is this correct?
Two main reasons:
#1: Your safety valve popped and the air is going straight out the safety valve. You should be hearing a loud hissing noise if this is the case. Press the safety valve back in and you should build pressure. Many such valves have a ring on them (to help you find them). It should be very near the pressure switch.
#2: You have a broken reed valve. A reed valve opens or closes based on the pressure it is under. It allows air to enter the tank on the compression stroke, but will not let it out of the tank as the piston strokes up and down. If it is broken or stuck open, you cannot build pressure.
and #3, a after thought, no extra charge ;-) The rings on the piston may have broken.
For #2 and #3, it will be necessary for you to remove the head to inspect.
First I think you paid too much if it won't run. The problems to look for are possible air leak from bad crank seals or blown out / broken cylinder base gasket or maybe a cracked carb spigot and if it has reed valves, maybe a broken reed. Also check the compression, it may have seized at some time and stuck or broke the piston ring.
