Question: 17cc-mx550

Bchb1

my unit starts and runs a few seconds then dies,what is wrong with it?
Hi Bchb1 IT could be any of many different things...but this time of year after these machines have been sitting all winter with the fuel in them going stale and getting GUMMY...it most likely is a fuel problem. A fuel problem starts in the tank and ends in the little diaphragm carburetor. Diagnosing problems other than dirt and gum takes experience and patience. If you remove the carb and decide to clean it, IMPORTANT THINGS...DO take pictures as you go, do NOT soak the carb in a parts cleaner or carb cleaner. Do NOT use the real strong cleaners on the carb like spray carb/choke cleaner. Also, do NOT attempt to BLOW out the tiny passages with high psi compressed link removed WD 40 to clean and loosen gum and varnish. There are many aids for doing this job including videos on this site and on You Tube.
Your machine could have OTHER problems as well, but most of the time, the problem is FUEL RELATED!
To be quite precise, your carb will probably need a little gasket and diaphragm kit installed in it because the fuel pump diaphragm has become dried out and stiff, no longer pumping the fuel. Ethanol and sitting with stale fuel contribute to this problem. They sell the kits to fix this problem on ebay. Not expensive, or you can just get another carburetor. You will need to know the MAKE and MODEL of your carb to order the correct G&D kit or replacement carburetor.
Wow, I thought my vintage 19cc Echo had a small engine.....17cc?? Can't find any pics of it.
