OK, lets slow down a bit. First look at the primer bulb of the carb. Depending on the type, there should be 2 or 4 screws right by the primer bubble. Carefully, remove the screws. The top section with the bubble and one fuel line will come off. In between them is a gasket and diaphragm. Look at the lower half and you will see a very small screen. Get some carb cleaner and spray by the screen but not too close. This is where most of the dirt collects. You might need to remove dirt by hand. Then close the carb. back up. Place gas in the tank, but leave the cap off, so you can look inside while you press the bubble slowly. You should be able to watch gas flowing back into the tank at a steady stream. Then place cap on and follow the start up instructions. Get back to me when you can.

SOURCE: replacing fuel line

Have you removed the carb. and tried to clean it? If not, get the numbers off the carb. and pick up a repair kit for it. Dismantle it, clean all orifices, remove the low and high speed needles (may only have one and count number of turns each one is at by screwing in until lightly seated then remove ) and clean passages with carb. cleaner. Reassemble, install, adjust initially with original settings and start. Adjust from here. Little carbs. are very "touchy" when adjusting.

You need to clean the carburetor. Remove and disassemble carb. Use a den Tek Brush, (used to clean between teeth), to clean the small portals in carb. Use a carb. cleaner while cleaning. Make sure the small screen in carb. is free of debris. The smallest of paticles can cause the carb. not to run right. Reassemble the carb. and try starting. If there is no change, then you will need to buy a carb. kit for your trimmer. Replace all appropriateparts: gaskets, diaphragm, needle valve, and the small screen.

SOURCE: Trimmer wont run when i take it off choke

No, it will not. Don't take the fuel mix screws out, it's not necessary.
You will need to disassemble the carburetor and spray with carb.cleaner. Make sure the small screen in the carb. is free of debris. Use a Den Tek Brush, (http://www.drugstore.com/products/prod.asp?pid=165357&catid=1152), to clean the small portals in carb. Reassemble and start.

(NOTE: If the cleaning doesn't work, then buy a carb. kit and replace all appropriate parts.)

If you need further assistance, just let me know.

SOURCE: Craftsman 32cc Trimmer Runs with choke at idle, then stalls

Sounds like somewhere you have a air leak. Most likely it's somewhere near the carburetor intake or maybe the carb itself. Could be a line from the primer if it has one and i do believe it should that could be leaking or loose. Good luck.

What will cause newish sears 27cc string trimmer only run on full choke?


If the trimmer has been sitting for a long time it is probably the carb needs to be rebuilt. Before doing that check the plug and be sure you are getting fire. Be sure nothing is blocking the fuel filter in the tank. Be sure exhaust or muffler is not plugged, with only 5 hours on the trimmer I wouldn't think that is the problem. Sound more like something in the carb. You can look on you tube to see how to rebuild the carb if you have not done it in the pass it is fairly simple to do.

Clean your carb for starters. Sounds like you have a fouled carb inside. If this is a trimmer you might need to just buy a carb rebuild kit and start fresh. Good Luck...

Weedeater is usable and ready, don't know how to start it


I hope you have fresh gas and 2-cycle oil mixed up! They always seem to start strong and explosively cut on good, fresh fuel. :D

1:Choke on.

2:Push the primer bulb (rubber ball by the side of the air filter) 3 times.

3:Place trimmer on ground. Grasp the handle, squeezing the throttle fully in left hand. Kneel and give that starter a crisp, sharp tug with your right hand. If the engine "hits", then push in the choke until off. Goto step 4.

If it does not give a hint of life, repeat the tug on the line 2 more times. If it STILL does not start, check for a distinct odor of gasoline. Likely, at this point, it is flooded, proceed to step 5.

4: With choke now off, continue to depress the throttle fully and give it another sharp pull on the starter. If it starts and revs? Let it idle for a minute to warm up, then go to work!

5:With choke OFF, press and hold throttle at full. It may take several pulls on the starter rope to see any life. If after 10 pulls and there is still no life, and still smells of gasoline - time to see the Ex about getting the trimmer looked after for some TLC. :D

Weedeater will not run with choke off


Check your carburettor mounting screws,they might be loose and it would mean the engine is
getting to much air and it would leak gas. Stephen
