Description:

This is a manufacturer supplied carburetor designed to work with Troy-Bilt gas powered blowers. Carburetor mixes air and gas before the 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 carburetor has a metal body and a rubber primer bulb. It is advised to replace gaskets (sold separately) when replacing carburetor to ensure top performance.

To replace this carburetor you would need a screwdriver.

• Remove air cleaner cover, filter and base
• Disconnect fuel lines and throttle cable

• Remove old carburetor
• Install new carburetor using two (2) screws
• Re-connect fuel lines and throttle cable

Questions & Answers

Is the carburetor for this Troy-Bilt backpack blower adjustable? Where can I find instructions for adjusting it? Thank You

Robert for model number Troy-Bilt TB4BPEC asked on 2019-05-19

Hello Robert, Carburetors are almost standard on most all two-cycle engines. Two-cycle engines require that oil is mixed with the gasoline fuel. Failure to mix the correct oil in the gasoline will result in permanent engine failure and damage. Adjustment of the carburetor may have to be performed on a periodic basis and most definitely after the simple device is rebuilt. Adjustment will not take long and the small screws may have to be "tweaked" after the engine has warmed up and been running for a few minutes. Step 1 Identify the two-fuel adjustment screws on the side of the metal carburetor. One screw is labeled "lo" and the other is marked "hi". The "lo" fuel screw is for when the engine is idling. The "hi" fuel adjustment screw regulates the fuel when the engine is at full throttle. Step 2 Turn both of the screws, gently, in a clockwise direction to seat the base of the screw inside the carburetor. Do not tighten the screws with any form of a forceful nature. When dealing with these small carburetors "finesse" is a key word for manipulation. Step 3 Open the fuel adjustment screws in a counterclockwise direction one and three-quarter turns to two full turns. This is the starting point for most fuel screw adjustments. Step 4 Start the two-cycle engine. Allow the engine to warm up for approximately one minute to two minutes. The engine may be running a little rough, that is normal until final adjustments are made. Step 5 Hold the throttle wide open for full engine acceleration. Adjust the "hi" screw until the engine smooths out. In other words, the engine should not be missing or have any hesitation. In most cases the "hi" fuel screw will not have to be turned more than a one-quarter turn in either direction. Step 6 Allow the engine to return to an idle operation by releasing the throttle. At idle the engine should be running smoothly. Quickly depress the throttle again. If the engine hesitates open the "lo" fuel screw to a quarter turn counterclockwise. Perform the release and depression of the throttle a few times. The engine should go from idle to full RPM in a smooth progression. If the engine pops heavily at idle, when coming down from a full throttle, the "lo" fuel screw is delivering too much fuel. Turn the "lo" screw in a clockwise direction using no more than quarter turn increments.

Equipment would run at slow speed but stopped when you move to regular speed

Remove the air cleaner assembly. Then remove the linkage and fuel lines from the old carburetor. Remember where the fuels lines go. Install new carburetor in reverse order. Started off quickly and would run at any speed. I have never had a problem with items purchase from Replacement Parts.

Quick Repair

The order process and delivery was smoorh. Received the carb and swapped it out in 5minutes. It's literally two thru screws holding the filter unit and carb to the engine. Disconnect two fuel lines and throttle cable after removal of scews. Assemble in opposite order to install new carb. Viola-back up and running!

Easy replacement

This is such an easy fix, about 5 minutes. Received the part very promptly. My only complaint, and not with your company is that I should not have needed a new carburetor in less than a year of purchase.

Guest - May 22, 2019 Verified Purchase

Worked great, but the idle bracket is plastic and was broken.

I decided to go ahead and try the carb anyway and was able to adjust the idle with throttle cable adjustment which works fine. Probably would be better to ship in a small box of some kind. I'm a happy customer.
