Product Description

?

This is an Genuine OEM replacement part used on Gas-Powered Handheld Trimmers. 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 Assembly includes a Metal Body Carburetor with Rubber Primer Bulb and Two (2) Rubber Fuel Lines. When replacing Carburetor it is advised that you also replace Carburetor Gaskets to ensure proper Air Tight Seal for optimum performance. You will need a Screwdriver to perform this repair.

Checked spark. Good spark. Checked fuel flow into and out of carb. Good. Engine symptoms seemed to point to carb but could find no foreign debris in carb. No carb kit available so ordered new carb. New carb arrived very quickly even though I live on an island in PNW. Removed original carb. Found new carb throttle cable hole too sm all. Drilled out to fit with no problem. Mounted new carb with throttle cable attached with ease. Fuel lines required some sort of keeper whereas old carb was ridged to retain solid fit. Used stainless wire to compress fuel lines on carb pipes but will probably have to replace them in near future as wire cut into them. Engine started and continued to run but seemed to be a little lean with no choke. With about 1/3 choke it runs very well.I.. I\'ll leave the settings as they are for now. I am not a small engine mechanic. Repair was much better than just tossing what seemed to be basically a good engine. Very cost effective over the shop or a new power head. Very pleased.

Removed 4 screws on top of the carburetor, removed the old primer bulb and installed the new one. I did not need the new carburetor and did not use it. It is a shame you have to purchase the entire carburetor in order to get the primer bulb which probably costs no more than
$.50 to manufacture. I also replaced the air filter by opening the cover and taking out the old and in with the new one after applying a little motor oil to the new one to distribute the oil evenly throughout and removing excess oil by squeezing it in a paper towel.

I have not used the brushes yet. They are for a different tool which is somewhat more complicated, but not as urgent.

I was extremely pleased that I was able to get the parts that I needed and in a timely manner. Thank you for your prompt service. You might also like to know that I had ordered the brushes from Sears but they sent the wrong size twice and then I was unable to get them to reverse their charge to my account.
