Product Information
Description:
This is a genuine OEM sourced replacement part used on gas trimmers/edgers. The purpose of this part is to mix air and gas before the fuel mix goes to the engine. If the engine won't start and the tank is full of fresh fuel, test the carburetor by removing the air filter and pouring about a teaspoon of fuel into the carburetor. Pull the starter rope. If the engine starts and then quickly dies, the carburetor is likely the problem. This is a metal body carburetor, it is sold individually. This assembly includes fuel lines, primer bulb. You will need a screwdriver to perform this repair. |

Tiller was not running
Spark plug was good and getting spark. Fuel was clean with no trace of moisture. Tines were clear of vines and weeds. Good compression and full of oil. Spark shield was clean and clear. This left only a fuel problem. Replaced carb ( no kit available ) filled with new fuel and it started right up. Hope to get five more years of great service out of machine.

Carburetor was no good due to owner leaving crap fuel in tank.
1. Removed engine cover, five screws.
2. Disconnected 2 fuel hoses.
3. Removed 2 screws from the side of the carburetor and removed carb gently from the gasket, I recommend changing the gasket.
4. Used super thin amount of blue gasket sealer to repair gasket and mount carb.
5. Mounted carb with 2 screws, put 2 hoses back on, put 5 screw for top cover, gas, primed until bulb filled up, pulled rope 5 times and it ran perfect. (GARDEN IS CULTIVATED AND PLANTED)
Thank You!

Diaphragm in carb went bad
Easy to replace carb, but I did trim the plastic flanges in the air filter housing to allow easier re-installation of two nuts. Also I locked the two nuts together to remove and re-install the air filter mounting screws.

Gov. ethanol in gasoline (4 stroke unit) had ruined the carburator replaced fuel system. Hard to start.
Troybuilt TB146 EC tiller - four stroke
1.) Removed the 4 - 5 top cover screws
2.) Removed the air breather cover, filter and filter grate, and assembly. See the spacers in the housing for the long bolts put them back, a big help to have.
3.) Removed the carburetor.
4.) Disconnected the throttle connection from the carburetor.
5.) Lift and discounted the throttle cable securement from the body of the motor, use two standard screwdrivers to push in on both sides of the holder, it just lifts off and out of the way.
6.) Remove the carburetor gasket, big cardboard piece. Remember to tuck in under the plastic housing when reinstalling
7.) Remove and reinstall the spark plug if needed, did they come pre-set, the carb too.
8.) Re-install in reverse.
9.) Change the oil while you are there. Do not overfill or it will run out of the air breather assembly.
10.) The power bit starter is great, all small engines should have one of these. A standard square bit, I bet would work too.

Great part, Great customer service.
I received the carburetor, installed it and it worked great. However the next day the primer bulb would not pop out. Seemed like a vacuum was holding it in.
I called Customer Service, and the woman was very helpful, she found the problem was very unique and wasn't in her troubleshooting guide. She sent out another one and provided me with a prepaid return label to return my defective one.
As easy as that.

Perfect fit
It would be better to provide new fuel lines and keep the line splicing connectors.

The carburetor fit perfectly and was an identical match for the original part. This purchase turned a useless string trimmer into one that worked like new!

Easy Repair!
Less than 5 minutes and my 12 year old string trimmer was running like a top again. Watched a quick repair video and the fix was so simple! I have the satisfaction of fixing it myself and saved over $200 in repairs!
