Carburetor and fuel problems can fall into several categories and it is important to determine what is
happening before proceeding with a rebuilt on the carburetor. If the carburetor is leaking fuel especially
while setting or just not getting fuel, you may have a contaminated fuel problem. You should look first at
the fuel in your tank for any signs of dirt, water, rust or varnish build up. Before you consider rebuilding
or replacing the carburetor you must have good clean fuel flow to it. When possible install the proper
fuel filter for your application. Non-fuel pump engines use a different filter then fuel pump engines in
most cases. It does no good to clean a carburetor and put contaminated or old fuel back into it. In some
cases a rusty or badly varnished fuel tank will need to be replaced.
Here's a list of things to think about when evaluating whether to rebuild your carburetor:
Does the engine run well under load, does it idle ok, does the governor hunt?
Is the carburetor in usable condition, throttle shafts, linkages loose?
After removing the bowl, do you have water corrosion, varnish or dirt?
Is there any sign of warpage on the mounting surfaces?
Is the float and bowl ok, are they pitted and possibly leaking?
Is the carburetor leaking fuel while just setting, possibly into the crankcase?
After evaluating the questions above, you will be able to make a more informed decision on whether to
rebuild or replace your carburetor. Clean up is important, especially if you have a varnish problem. If you
have a water corrosion problem, which looks like a white powder rust, you may want to just replace the
carburetor. Carburetor cleaner will not clean water corrosion.
Do not take the carburetor totally apart until you have the repair kit. You do need to determine if you
need a new float, bowl or other parts not included in the repair kit. Most repair kits include a needle
valve and all gaskets.
