My gentro gg10020 stop running and now has no spark to start

You're positively sure it ran out of fuel<?>. If it merely ran out of fuel then likely the fuel pump has vapor locked. If you didn't FILL the fuel tank, do so and try again (the trick here is to get the fuel level in tank higher than the fuel pump). Attempt start, if still no run then try starting fluid.

To be successful using starting fluid, remove the air filter to expose the carburetor intake. Spray a 1 second burst of starting fluid directly into the carburetor throat (you don't have to reinstall the air filter, yet). Promptly crank engine.

If engine cranks but no run, then either no spark or engine is flooded. If it runs for a couple seconds and dies, then fuel from tank is still not reaching carburetor. Repeat attempt with starter fluid. Comment here with results for further assistance if needed.

Be sure to reinstall air filter before returning to mowing.

OHV engines require periodic valve adjustments.

Sounds like you are in need of a carb diaphragm. Also be sure you do not have a vacuum leak on the carb to block connection. You could also have a little water in the fuel. Cheap fix, rubbing alcohol, about a half cup. fill tank with fresh gas and run it through.


My thoughts.......................................

Could be a venting problem with the tank. Will it start if you leave the gas cap off ?

(if engine is good, not overheated )
its only 1 of 2 things.
lost spark (do a spark test using , yes, a test good spark plug)
if spark is good on all cyl
then check fueling, if spark plugs not soaked in fuel (tips)
then try test fuel.
if soaked, the op guide says, hold throttle fully open (depressed 100%) this cuts INJECTIONS 100% and you start a flooding motor)

You need to check it is mechanicaly sound, a compression test will give you a good idea, anything under 110 psi and you have a problem with either piston/ring wear, or it has seized.

check and make sure its getting fuel. when trying to start, spray some engine starting fluid in spark plug hole. just a little bit. replace the plug then try to start it. if it starts then quits then its a fuel problem. fuel not reaching engine. good-day !

dose it fire

Stihl weedeater was running and stopped suddenly. Put in a new fuel filter and cleaner air filter with soap and water. Checked spark plug and it appeared fine. Started the weedeater, ran for a second or so and stopped. Spark plug wasn't gas fouled. Could it be the carburetor needing new diaphram gasket and spring.
