Tip & How-To about Garden

Avoid starting problems in power equipment

Dont just run the engine till it stops with gas shut off. this does not remove all the gass from the carb and fuel system. make sure you drain the tank and the carb completly to avoid gum and varnish developing during storage.

CAUTION! Those motors are notorious for this problem and can be dangerous to a degree. I would be willing to bet if you pull the oil dipstick out and smell it it have a hint of gas smell to it. The problem is in the carburetor. Most of those carbs have a brass seat which is not repairable. What is happening is the needle is not seating good and letting fuel constantly but ever slowly flow, thus draining into the motors crankcase and eventually overfilling it and then filling the exhaust system which is the reason for the backfiring. To test this theory, keep in mind this is NOT a permanent solution. Clamp the fule line off if there is not an inline shut off, next drain the bowl of the carb, then remove spark plug and crank engine over several time to clear out the build up, next open fuel line back up just long enough to refill the bowl of the carb and close it back off. If the engine will now start and run till carb runs out of fuel this is your problem and if that particular carb has the brass seat you will need to just get a new carb. ALSO you will need to change your oil and filter to get rid of the fuel in it! Hope this helps.

still not getting the gass


Remove the float bowl and spray out the needle and seat this should clear it out, you will know if it is cleared out when the gas flows out of the needle and seat, be careful not to bend or be rough with the float, if the gas line has a petcock or shut off valve on it ensure that gas flows through the line by removing the line at the carb and see if gas is reaching the carb if so then the needle and seat is gummed up.

I have a coleman powermate 5700 generator with a 10HP Yamaha MZ300 engine. It set most of the winter and it will not crank. I have verified that fuel is getting to the bowl. I have cleaned the carberator the best I could. I have replaced the spark plug. If I shoot gas in the spark plug hole it will fire for a second. If I use starting fluid in the intake it will fire for a second. I am just not getting fuel through the carberator to the spark plug.


Bascially you need to completely remove the old, stale fuel to start with. (you can use the old fuel it in your lawnmower mixed 50:50 with fresh fuel to use it up).

Then once you've drained the fuel tank, you'll have to clean out the carb with a Fuel Injector and Carb cleaner. Really spray the carb till it's soaked, since you've got a schellaced fuel system.

Make sure you remove the air cleaner so you can get the spray into the carb. Also, with the spark plug removed, and the power switch turned "off", so the generator won't try to start during this process. You can also slowly crank the engine with the pull starter, to help work the cleaner through the system.

Then let the unit set for about 10-15 minutes, so the cleaner can evaporate, etc. and then you can reinstall the spark plug.

Now add about 1/2 gallon of fresh fuel and you can try starting the generator. You might have to use some starting fluid to get it started, by carefully spraying it into the carb in very small bursts to keep the motor running

Once it's running smooth, you should always use fresh gas and make sure to add a quality fuel stabilizer, such as Sta-bil, to the gas you use in the generator, as it will keep the fuel system protected for up to 2 years.

I also always turn off the fuel shut-off on my generator to use up the gas in the line before storing it. Also, you should get the generator out at least every 3 months and run it for 15-20 minutes to keep everything working and lubricated, so it will work when you need it.

Just be sure to always add more Sta-bil to your fuel and turn off the fuel shut off and let it run out, before storing.

I've done this with my generators and they're now over 14 years old and always start on the first pull and run like tops!

If you can't get the unit running smoothly, you may have to take it to a small engine service shop for them to do a "tune-up" for you.

Hope you find this Very Helpful and best regards!

Fuel Leak from the Carburetor


Remove the water trap bowl at the bottom of the petcock, (gas valve). Is there any water or trash in the bowl? Dump it, clean it and re-mount it, ( not all bikes have a water trap bowl ).

Drain the carburetor. There should be a screw on the lower side of the carb float bowl. Remove the screw then replace it after the fuel drains. Turn the gas back on and wait a minute for the carb to fill with gas. If the bike doesn't start and run properly then shut off the gas and remove the carburetor from the engine.

Remove the float bowl and clean the entire carb with a spray carb cleaner from the auto parts store. Wear protective goggles to avoid getting spray in your eyes. Spray into all the little airways and fittings in the carb. Check the float as they can go bad and fill with gas such that they no longer float. Remove the idle screw and the air screw on the outside throat of the
carb and spray into the screw holes as well.
< < READ CLOSELY > >
Be sure to put these two screws back in the same hole they came out of. IMPORTANT > do not tighten these two screws down. Only screw these in until they LIGHTLY seat. Now turn each screw one and one half turns outward. Put the rest of the
carb back together, clean the air filter and install the carb. Let the float bowl fill then start the engine. The idle speed will probably different so adjust the idle screw to get back to where it was. This process should get you back on the road.

Drain the carburetors. There should be a screw on the lower side of each carb float bowl. Remove the screw then replace it after the fuel drains. Any water in the gas? Remove the water trap bowl at the bottom of the petcock, (gas valve). Any water or trash in the bowl? Drain a cup of gas from the tank. Any water or trash in the cup? Dump it, clean it and re-mount it, ( not all bikes have a water trap bowl ). Turn the gas back on and wait a minute for the carbs to fill with gas. Install a new stock NGK spark plugs and try to start the engine. If the bike doesn't start and run properly then shut off the gas and remove the carburetors from the engine.
