    Bonjour





    I have the same problem with a 260 polan 42 cc she was starting good but a soon that I pull the trigger she died



    I checked a the hoses very closely with a magnifying glass and found crack in the hoses witch was sucking air instead of fuel



    In cheeked the gasket between the engine and the carb and found crack in the gasket same thing as the hoses sucking more air than fuel.



    So replace the hoses and a knew gasket once started she still running, jus bit of adjustment and there u are on the go



    I hope it will help you, my English is not very good.



    Bonne chance

Check the fuel line for cracks. That is usually the problem. Plastic fuel lines crack with age and need to be replaced. I have had a couple of Craftsman Saws (made by Polan do the same thing).
Fuel line can usually be purchased at a hardware store or saw shop. Takie a piece of the old line with you to get the right size.

I'm only familiar with stihl saws. On these there are three screws labelled H,L, and LA. Check your owners manual as like picatudo suggested, the factory settings of the H and L screws may need adjusting.
Another way to check for leaks is spray carb cleaner over the cylinder head while running the saw. If the rev's change it's sucking in the carb cleaner and the cylinder head gasket may be leaking.

I have a Ariens snowblower deluxe 30 which is a year old. Starts fine and will run. Unfortunatley it is running way to low. I have replace the gas with fresh gas ran it through completely


It is very possible the carbureator needs a cleaning. Moisture can corrode the inner parts of them if left all summer. I find that the fuel usually does not go bad over the summer. I always start my snowblower once a month over the summer and then have no problems when the snow flies again. There was a time when mine was losing power and quitting also. There is a screw on the bottom of my carbureator that needed adjusting. If you are lucky that may be all you need. By turning mine in and out a bit I found the spot where the gas was correct and it worked fine again.

Talon electric chainsaw has no power, changed the fuse etc...any ideas??


talon chain saws have two control switches before they will start. One is the trigger that you pull and the other is a button or lever that has to be held in at the same time. These two controls mean that you have to have both hands clear of the chain before it works.

Hi we have a Massey Ferguson Dyna 4 5465 and it was working this morning and then it died we started it up and it ran for about 1/2 a minute when we try starting it now we can hear the fuel pump runs for...


am i to assume its a diesel ,if so sounds like its out of fuel but i could be wrong as its been many years since i have worked on tractors and all the fancy electronic gizmo on modern vehicles can confuse me.Now firstly check the key as no doubt as its a modern one it has a immobilisor and if the head of key loses its chip inside the key head it will never start unlike the old ones that would run on paraffin diesel or petrol ,the later ones were diesel only but again providing they had fuel and oil with the rad topped up they ran 24/7 ,thats a point check the oil level if its low it may stop the engine from starting
