It is quite unusual for them to exude fuel from the carb, if somebody has removed the carb at some time it is possible they have re connected the fuel hoses incorrectly, it is important to remember that the fuel bubble is a purge not a primer, so it pulls full from the carb into the bulb and back to tank, if the hoses are incorrectly assembled you can push fuel into the carb, this would cause fuel to exude from the carb.

SOURCE: I need to rebuild the carburetor on a Stihl model

I don't have a diagram or the part numbers to the minor and major repair kits, but a Stihl dealer should be able to help. Tell him you need a kit for a ZAMA C1Q type carb. The exploded view should be with the kit.

If the plug is dry than you have some sort of blockage still in your carb you need to go in and really clean all the little orifice's and screen if it has one. Dry plug, no fuel, carb clogged simple small engine dynamics.. Good Luck! Don't forget the thumbs..

SOURCE: my poulan chainsaw will start

One thing you might check is the vent on the gas cap to make sure it is not plugged. I have had them plug tight and not allow fuel to be draw on accelleration. Hope this helps you. Thank you.

My Stihl FS85 runs good for about 20 seconds and then shuts completely off. I have replaced the Plug, cleaned out the fuel system and it still does the same thing. Could it be the coil?

Sounds like the main jet or the diaphrams in the carburetor are deteriorated. Remove carb and soak in a good carburetor dip style cleaner and rebuild with a new kit. Also replace the fuel line and filter and use a fresh gas mix.

Stihl FS200 repair manual

I just saw this deal on the Fs200 Stihl Brushcutter. Equipped with a Zama c1qs51 carb. Junk the carb. Go to a stihl dealer and buy a three screw chainsaw type carb with a high low and idle screw. The c1qs51 is junk.The three school carb will put an end to your worries. Of course change your fuel filter naturally. I guarantee this will fix the thing. I own an Fs200 and Fs250.

When i give my stihl weedeater (fs 55) gas it dies. i changed the gaskets in the carburetor, new spark plug, new air filter. it idles fine just when i give it throttle it dies

This could be from a bad fuel filter (has a dark appearance when dry), from the spark arrestor screen in the muffler being plugged up with carbon deposits (take out the spark arrestor screen and clean it by burning off the carbon deposits), or the carburetor needs to be adjusted. If the carburetor needs to be adjusted I would take it to the nearest Stihl dealer that has a Gold Certified Technician. That way the unit is adjusted properly and is in good running condition. You can find a local dealer with the dealer locator. The link is HERE.

Stihl 420 - continues to cut out , we purchased 4 new saws and have problems with all of them. We thought it must be gas , ethanol, vapor lock any suggestions

If the unit is running for a short amount of time but never gets to a high rpm then it could be that the needle is sticking open, or another carburetor problem. Might also blow the fuel tank completely dry, I have seen where the water would stay in the fuel tank even after it has been drained out. And when the tank is empty I would check the fuel filter. Take the fuel filter off of the fuel line and dry it off. IF the fuel filter is dark, like a coffee stain on white, then you need to replace the fuel filter. If it is a white color when dry the fuel filter is O.K. and the problem is elsewhere.
I would also suggest that you take it to a Stihl dealer that has a Gold Certified Technician, the technician will be able to diagnose and fix the problem. Usually in a timely manner. You can go tot the dealer that you bought the units from or you can go to the Stihl website and they can direct you to the nearest dealer.

Starts fine runs good for 1-2 minutes then dies. starts up with several pulls or choke. then dies again. changed the sparkplug no differance. cleaned the airfilter same result. george from texas

Check the fuel filter and muffler for plugging. Check the fuel tank vent for plugging. Check the fuel lines for damage or decay. Check all of the carburetor fasteners for tightness including the mounting hardware for the carburetor to the cylinder. The carburetor does not appear to be pulling new fuel into itself after running on the initial prime. If the above hints don't help, you may have to service the carburetor. Check the gaskets and heat insulator block behind the carburetor for any obstruction/damage of the impulse passage which allows the carburetor to pump fuel. Hope this helps!

Check the muffler for plugging of the arrestor screen. If no help, check the carburetor for a hardened diaphragm or any plugging. Are you getting fuel into the primer bulb when pumped several times? Make sure the primer is pulling fuel from the carburetor by removing the line that goes back to the fuel tank and place a small cup or can under the primer port that the hose came off of. Pump the primer several times--it should push fuel out each time. If not, place the carburetor line on the other port and repeat the process. The pump must pull fuel FROM the carburetor to properly prime it. Barring a blown crankshaft seal, the engine should start. Hope this helps!

Some one played a bad joke on me they put antifrezee in my gas tank and what to do to get out

Take to a garage and you will soon find out that "bad joke" is the wrong name for this. All gas must be removed and gas tank dropped and cleaned. you can only hope that that will fix it. Fuel pump, line and injectors may also need attention.

Your carburetor needs cleaned or you need a carb. kit depending on how old the carb. parts are. If you need tips on carb. cleaning, feel free to ask.
