27cc easy crank craftsman carburetor

The power source comes from the ignition module(coil), Power is stepped down internally in ignition module to something between 9v and 18v(can't remember exact voltage for sure at this time).

I don't recall seeing one on that model go bad. usually it ends up being the carburetor. Or incorrect spark plug that is the culprit(If cylinder is O.K. and you have spark).

Hope this helps.

I need to ask. Did you leave fuel mix in it for a long time? If so then the carburetor will need to be cleaned with a special cleaner. and not the spray can stuff.

There are 2 fuel lines going into the back of the primer bulb. One line goes from the back of the bulb into the fuel tank, and the other goes from the back of the bulb into the carburetor. I believe that the line that goes into the fuel tank has disconnected from the back of the bulb. You will need to remove the bulb, find the line that dropped off of the bulb and into the tank, and reconnect the line to the back of the bulb.

check age of gas. Cannot be more than 30 days old.
Make sure to use fresh gas w/synthetic 2-cycle oil @ 40:1 ratio (1 gal.) Gas to 3.2 oz. Oil). Do not use old or stale oil/gas mixture. Always use the proper oil/gas mix. If you do not, your engine will suffer rapid, permanent damage.May need to clean or replace carburetor.

May need slight adjustment on carburetor, but need special tool.

When you cover the air bos, you are in essence, enriching the air/fuel mixture that is entering the engine. The carburetor does this when it is needed and when it is functioning properly. For the bogging problem, it is evident you need a small carburetor adjustment. I suggest turning the L mixture screw (the one on the carb closest to the engine) out (counterclockwise) 1/8 to 1/4 of a turn. The heads of the L and H mixture screws are unconventional type and some improvising will have to be done to enable you to get ahold of them to adjust them. I use a small plastic (22 gauge) automotive-type wire connector with a ring terminal end on it. I tap it down onto the screw head with a small ball peen hammer until it stretches around it. I then am able to turn it. Try the suggested adjustment for your high-speed bogging problem. And to further tune and adjust the carburetor on your machine, I highly suggest you look at the following tutorial.
