It's too lean; not enough fuel mixed with the air. Look for the main mixture screw--it should be a large screw with a spring under it on the carburetor. Run the engine until it's warm.
With the engine running, turn the screw outward (lefty-loosey) about 1/8 turn slowly and see if it improves. Slowly turn the screw back and forth until it runs best with the choke completely off. Then set it 1/8 turn richer (turn screw outward 1/8 turn) than the best position.
Reason for doing this: Conditions change, even the barometric pressure. Small engines run okay if they are a little rich but not if they are a little lean.
the motor wont rev high on choke.the motor is suppose to fire once on choke. then turn the choke off.pull the start cord and the motor should start and run.check that the throttle conrol is on full. it should run fine.
When the compressor comes up to pressure and kicks off, you should normally hear a gasp of air escaping. That gasp is the release of pressure from the compressor itself - not the tank, and it is supposed to get released so that the compressor can restart without being preloaded with compressed air. My guess is that the gasp is not happening. It is probably some debris or a gummy mechanism. The mechanism is supposed to be triggered by the same mechanism that shuts off the motor.
sounds like the carb needs to be removed and cleaned. It the chunk of metal that has the fuel line going to it on top of the engine.
Use a phillip screwdriver and possible a small ratchet to break it down and clean it thuroghly with gasoline.
After you get it back together and have cleaned it up as much as possible, crack her up with full choke again. this time though, allow it to run and barely ramp up the rpms enough to give it a little lug. When the engine seems to begin losing power, (these adjustments should be as small as possible until you get her running smooth) dial the choke back just enough to ramp up the rpms. This will probably take a few tries, but most definately should work in your case.
Once the trimmer is running smooth with the choke off you will be good to go.
Many times our trimmers and other 2cycle engines dont get the proper attention to keep them running up to par. Take the time to consider the unique properties of your tools to determine any possible future repair. Anytime you have and engine that burns a home mixed fuel there will be the risk of trash in the fuel system
What engine is it? The plug gap should be preset, But I'm glad you mentioned the compression, it should be 100 lbs.. , 70 lbs min, or it won't start. You might have a valve burned out from the choke being on. Most engines won't run with the choke on, so something was wrong. You can pull the head and the valves easy enough to see what it is. One more thing, make sure there is nothing holding the engine back from running, like the pressure washer is full and ready to go, let the pressure out if you can. Hope this helps.
You have a few possibilities. Make sure you have good fresh gas in the tank. You're not getting enough gas, so choking helps get more gas than air, making it run better. Could be the carb diaphram (not very expensive if you replace yourself), when they get old they don't perform like they should. Could be the filter in the gas tank is bad, plugged. Also might be just an easy adjustment on the carb Low, and High speed screws. The choke has three positions, full choke, partial choke, and no choke, which means run position.
HI, Turn off the gas and take the bowl off the carburetor.Look for water bubbles in the gas that spills away. Water will float like little balls on gas. If so drain gas tank put in new gas with some HEET added. While you have the bowl off spray up and around the bottom of the now exposed carburetor. Pay attention to spray up the small copper tube in the center of the carb. Clean out bowl and put it back on. Turn on your gas. Look for leaks around the replaced bowl. Good luck.
Jets in chainsaw may have build-up. A good build-up remover is called SeaFoam. Add this by direction to the gas. When using the SeaFoam you need to run full throttle with intermittently full choke until motor runs smooth with no choke.
Double check 2-cycle mixture. Too lean mixture in the chainsaw wont stay running.
Yes. It sounds like you need to clean the carburetor. Take the carb. off, disassemble and spray with carb. cleaner. Make sure to clean the small screen in carb. Clean the small portals with a Den Tek Brush, (used for cleaning between teeth). They work great for this job. Reassemble carb. and try starting. If this doesn't cure the problem then you will need to buy a new carb. kit and replace the needle valve, gasket(s), diaphragm, & small screen.
