Poulan 18" wildthing chainsaw (model


This could be a couple of things, if the fuel tank brather is blocke the tank will vacume, to test this try slackening off the fuel cap when the saw starts to die, if it picks up again it is a fuel tank braether issue, the other possibility is a bad ignition unit breaking down, the only test for this is to replace the unit and try again.

Chain saw ran for a few minutes became hot with little smoke and now will not start again.


It could get hot and not start if the saw was quite dirty because it relies on air for cooling and if the fins can't get enough air around them it would heat up and not start. Another thing is if some one did not use the correct gas oil mixture it would get hot and score the cylinder lowering the compression causing it to not start.

Chain keeps slipping off when in use.


Make sure the chain has not been damaged from past slipping by removing it from the machine and laying the chain out in a large circle on a flat surface. No part of the chain should be standing free of the surface--replace the chain if it does. The chain should be adjusted so that the chain just comes up to the lower bar edge, but not so tight that the chain cannot be turned by hand. Make sure the teeth are quite sharp for maximum cutting effect and minimum heat. Check the chain lubrication by running the bar tip at speed for a moment or two near some cardboard--it should throw off a thin line of oil. Don't continue to run the saw if the chain starts to droop from the bar. If it is quite hot, allow it to cool which should re-tighten the chain. Hope this helps!

might pay to check the fuel tank breather , make sure its venting

check the ignition coil it may be going open circuit loosing its spark when it getts warm or hot , you have to wait till it cools to re-start

you will need a spark tester fitted in between ht lead and plug to check this visually when its running

check for a kill wire grounding 1st

Hot chain saw wont start


When it won't start, remove the spark plug, lay the base on engine metal with the wire on, and pull through. The spark should be blue and snappy. If nothing, try a fresh plug. If still nothing, the ignition module may be failing with heat. Try blowing out sawdust from the engine and case with compressed air to improve cooling. Does the engine 4-stroke when not cutting, but immediately 2-strokes when cutting? Check the air cleaner and muffler for plugging. Make sure the carburetor fasteners are tight. Hope some of this helps!

My saw runs a few minutes then gets hot and wont start


What is the ratio of the oil/gas mix?
Sounds like it is not getting sufficient lubrication.

Add 1/2 oz (about 1/2 shot glass) of 2-cycle oil to the gas tank and try again......

Check to be sure that you have LOTS of chain oil in the chain oil tank!!

2000 silvarado 5.3 vortech runs good for awhile after it gets hot it shuts off and wont crank until it cools off


do you mean wont crank over and start till it cools off? if thats the case it sounds like you got a bad crankshaft position sensor,,thge sensor is fine when its cold and warm but when it gets hot it goes open and the cars computer cant see the rpm and shuts the engine off,and then when it cools off the sensor works again and the car starts and is ok till it gets hot again,if thats the case thats what it is,,,hope this helps,,,about $100 for the part

Wont run hard start, run for five min or less then wont start


Many chainsaws have the fuel tank mounted very close to the engine cylinder. In the process of filling the tank over and over a lot of mixed gas is spilled and some of it runs down on the cylinder head. Being mixed gas and having oil in it, it leaves an oily residue. This oil will seem to collect a massive amount of sawdust over time. The sawdust coating the cylinder causes it not to cool down really well and the increased heat can cause the fuel in the tank to boil if it's bad enough. If the vent in the fuel cap is plugged and the gas in the tank gets hot it tends to pressurize the gas tank. This can cause the saw to flood out or load up.

Change the gas cap or clean out the vent filter. If you can get to the cylinder clean all excess oily sawdust from the cooling fins.
If you get the saw running your probably should readjust the mixture settings.

You need to set the mixtures for the carburetor. You will find a Low and High adjustment screw. At idle turn the screw in or clockwise until the rps starts to decrease. Then start turning it out till you hit max idle rpms. Turn screw back in a quarter to half turn and it should be idling smoothly. Be careful here and get someone to hold saw if necessary but hold in throttle to full speed and do the same with high adjustment screw. turn it in till rpm starts to drop then back it out until you get to max rpm and it won't go any higher then turn it back in a half a turn.

91 tempo heats up and quits wont start until engine has cooled


I had the same problem with f-150. the timing chain would stretch when it heated up and cause it to quit and naturally it wouldnt start until the chain cooled down and tightened back up.

Runs fine for approx 15 mins,then stalls out and wont start again


sounds like coil problem, coils will start cold then get hot and stop. when coil cools will crank up and run till it gets hot, try to replace the ignition coil,dont think it would be a crank sensor, try a coil,thanks robert b.
