How to Install a Carburetor

In this article we will go over how to install a carburetor in any type of machine that is not fuel injected. This process is nearly self-explanatory but sometimes it helps to have a second opinion.

Difficulty: Moderately Challenging

Instructions

Things You'll Need:

• Screwdriver (Phillips and Flat)
• Carburetor
• Wrench to attach clutch and Throttle (Size varies)

1. Remove old Carb.
   
   If you have an old carb and need to remove it, follow these instructions. Unhook the choke cable(s) and make sure there are no loose parts when you let it dangle. Chances of loose parts are likely. Now, remove the throttle cable. Both the throttle and the choke(s) will take a wrench or maybe even two wrenches. I recommend using a permanent marker and marking the bolts where everything was set to prevent from too much tinkering at the end. Search the fuel line for a switch. If you cannot locate one and cannot terminate the gas flow, just unhook the gas line from the carb and quickly plug it with a small screw or something along those lines to plug the gas. Now you can remove both the clamps from the cylinder and the air supply. Your old carburetor should just pull loose with a little tug now. Once you have the old carb out, move on to the next step.

2. Set the carb to engine specifications.
   
   You will want the carburetor to be set at the proper specifications found in your owners manual. If you are not sure how to do this or don't have the right tools, find a mechanic. Settings include the Air/fuel mixture, and the timing if there is more that one carburator.

3. Set the Carburetor into place.
   
   Now, remembering how you removed the old carburetor, place the new carburator into place starting with the cylinder. Pop the carb into the cylinder slot and then attach the air supply box. Now tighten them down.

4. Attach the choke and throttle.
   
   Insert the loose parts, if any, back into the choke cable and carefully drop it into place and tighten it back down accordingly. Do the same with the throttle. If you followed precautions in step one, you will know where to stop when tightening these two/or more cables down.

5. Adjust accordingly.
   
   You will now need to adjust the settings accordingly and check to make sure everything is running smoothly. Check the choke, air/fuel mixture, throttle, and timing. Thats it!
