Chainsaw runs w choke speed up, cuts off when choke is off

There may be a number of errors in the saw, or one of several.
If you have lots of used chainsaw or chainsaw has stood for a long time. Then the problem can be broken crankshaft seal.
Another possible problem is - improperly installed or defective carburetor gasket.

Craftsman YT 4000 Won't Start

Did you check for "spark" at the plug? Check fuel filter ( maybe plugged up ". How fresh is the gas?

Clean or change air filter. Clean, gap or change spark plug. Empty gas tank add fresh gas with Stabil. When spark plug is removed pull rope several times to blow out cylinder. Spray starter fluid in spark plug hole before replacing spark plug. Clean outside of carb so choke works freely. Spray starter fluid into carb breather hole with air filter removed and try to start. if running replace air filter and cover. If no start disassemble carb and clean. If no start replace carb.

Riding lawnmower turns over but will not start start

Could be several different things causing your problem. As a mechanic i've learned to never assume anyone has checked the obvious. So, since you didn't state what you may have checked:
1: Check to make sure you have gas in the gas tank
2: Check to make sure the spark plug wire is still pluged to the spark plug.
3: Check to make sure the fuel shut off valve on gas line going from tank to engine is in the fully open position. You may even want to remove the fuel line from the tank (putting a bucket below the valve to catch the leaking gas) and observe the flow. If it looks like it is coming out quickly, then I would guess that is not the problem.
4: Check the fuel filter in the same manner as above. Locate the fuel filter and remove the fuel line on the side of the fuel filter that is closer to the engine than gas tank. You should observe a similar fuel flow from the line as from the fuel shut off valve, if not, replace the fuel filter. They are cheap, so can't hurt to replace it if you are in doubt.
5: Check airfilter to be sure that it isn't clogged full causing the engine to draw in to much fuel and flood the engine.
6: Remove sparkplug (usually either a 3/4" socket or 13/16" socket and ratchet will remove it) and inspect the plug. If the spark plug has a lot of black soot between the electrodes then it is fouled out and needs to be cleaned, it could also be bad and need replacing. They are cheap and easy to replace, so in my humble opinion, when in doubt replace the spark plug. If the spark plug has a lot of fuel smell and it is wet, then the plug is either bad or choke is stuck in the closed position (or some call it the on position) or possibly the airfilter is clogged. If you checked the air filter earlier, and it is clean, then check the linkage for the choke to see if it is stuck in the closed or on position. To check it, remove the air filter and look down the large hold in the center and you should see a metal vane in an upright position for the choke to be in the open or off position. If the spark plug isn't fouled out or bad, or its new, and the plug isn't wet, then proceed to #7
7: Now that you have checked all of these simple things, you will need to give more information or take the mower to the local lawnmower shop and have it worked on by a reputable technician.

It doesn,t turn over at all has new spark plug bowl is full gas lines are good pull cord is good help

Remove spark plug and and ensure there is actually a spark when the machine is cranked.
Ensure air filter is clean. Foam elements can be washed with hot water and detergent, squeezed dry in a cloth and re-oiled with a teaspoon of engine oil spread through the foam. Paper elements can be cleaned with compressed air blown from the inside of the filter but ideally should be replaced.
Check fuel lines aren't kinked or blocked restricting fuel flow.
Ensure fuel filter isn't dirty. This is probably located at the end of the fuel line in the tank.
Remove the air filter and check the choke plate closes ok when choke is turned on.
Air locks in the fuel lines will also cause this symptom. These can be caused by running the machine with low fuel level in the tank and cutting upside down or at a sharp angle.
To remedy this keep pressing the primer button i present until it feels spongy and fills with fuel.

Petrol Engine will not start. The saw is a Stilh and I have not usaed it for 18 months

Ok first off drain all fuel out of the saw replace the fuel tank filter, then clean out the air cleaner, pull the spark plug out and with some and paper sand the spark plug so that it's clean. NEXT mix some new gas mix and add to the tank try putting the choke on full and pull rope about a dozen times then put choke in partial open and try starting. If it does not start pull spark plug and pull starter rope and see if you have spark if you do add a capfull of gas mix into the spark plug hole and tighten the spark plug down and try pull starting if it fires off and dies then you have a cracked fuel line and need to replace the fuel line. When you have the plug out spray a small amount of WD 40 into the sparkplug hole and pull the rope a few times to get rings lubracated then add the gas. If it won't start post here and I will give you more directions to test for starting again. HOPE THIS HELPS AND THANKS FOR USING FIX-YA.

Wont run without choke being pulled out 1/4 .

-Remove Carb and clean, you have a high speed fuel port clogged.

This would also be a good time to replace your fuel lines, Take photos before you start.

-Drain all fuel from the Saws fuel tank.
-Remove and REPLACE with a NEW spark plug.
-Remove and RELPACE with a NEW Air filter.
-With spark plug and air filter removed and fuel drained pull the starting cord many times 12 or so to ensure there is no fuel in the chamber and also check for a spark at the plug.
-RE-MIX WITH NEW FUEL your 2 cycle oil to the correct ratio in a clean fuel can. it is OK to dump some in the Saws fuel tank slosh around and dump out in an approved container for disposal.
-Hold off on putting back on the air filter until you have had it running.

Hope this Tip Helps.
