SOURCE: 55cc air induction chain saw wont start,keeps flooding

what do you mean by flooding?
if it is overflowing?
try to remove the 4 screw underneath the carb,
take out the diaphragm,and then followed by float valve..
there is a tiny spring,be very careful...
stretch the spring a lil bit more at about 2mm...

as time passes,the diaphragm deteriorate and one way to correct them is by stretching the tiny spring to give more strain on the diaphragm...

this is what i did if i am too lazy to go out and buy the diaphragm kit..
only 10 bucks...hehe

Was using saw ran fine stopped and returned next day will not start fuel fine new plug filterers gas and air still wont start took to local chain saw repair shop they said that because it had water in gas...


check the carburetor. If you have a stiff diaphragm then it won't run.
I have seen them that behave just like that. They will run fine, turn it off for a few minutes then they won't restart. WD40 isn't going to get it to run either, try a small amount of mixed gas right into the carb. It should run for a minute until the gas you put in runs out then die. If it doesn't run then you have a bigger problem

I am using a borrowed Husqvarna model 51 chainsaw (aprrox 18") and having a problem with the chain seizing up. It worked fine for 30 minutes or more, and then the chain suddenly had much more...


Sounds like the bar is to tight.There should be a cover and 2 studs,loosen the nuts and then look for an adjusting screw at the back of the bar and back it off.The chain should have about 1/8 slack when pulled from the bottom of the bar.A tight chain will heat the bar and turn it blue close to the chain guide.A new bar will be required.

Try removing the fuel cap for a moment, then try restart. If ok, check the fuel vent for plugging. Check the fuel filter for plugging. Inspect the fuel lines for decay or other damage. Check for spark when it stops--it may be the ignition module failing when hot. Check for sawdust and dirt plugging the ventilation system--blow it out with compressed air. Does the engine 4-stroke at speed when not cutting, but does 2-stroke when cutting? Make sure the chain is being oiled while running. Hope this helps!

Chain keeps losening up


Is the chain being properly oiled as it runs? Check by running the tip of the bar at speed near a piece of cardboard for several moments--it should throw off a thin line of oil onto the cardboard. If nothing, remove the bar and chain, start the engine and observe the oil port in the side of the engine case. At speed, it should ooze out oil. If so, clean the bar drive-end holes that feed oil to the chain. Pay particular attention to the two small holes that run from the large holes out to the chain groove. If nothing comes out of the engine port, then an inspection of the pump, lines, and tank filter are in order. Make sure the chain is properly sharpened as a dull chain makes a lot of heat which allows the chain to stretch. You should not have to apply high force to the saw to get it to cut. Set chain tension so that the chain does not droop from the bar bottom, but turns easily by hand. Hope this helps!
