Check the seals on the crankshaft for a leak and the ignition module for a loss of spark as it warms up.

SOURCE: 029 stihl wont start

Disconnect the stop switch to rule out a problem here, if there is still no spark with the plug out and earthed against the cylinder, then it sounds like a replacment ignition unit is required

Why does my 93 Caravan Start fine and run great till it warms up then dies and wont start untill it cools back down.


I had the same problem a few years ago and it was the coil pack breaking down. If it starts missing before it dies id get a new coil pack. Before u buy a coil pack you need to get it warm again and just before it dies look underneath the vehicle to see if the catalytic converter is starting to get hot, if it is hot and usually getting red hot, its stopped up.It will fool you in to thinking that the coil is bad.

The KM90 is a 4 mix engine and regularly needs the valve clearance tightening up, remove the orange housing, under there you will see the rocker cover, held on by 1 screw. The valve clearance tool can be bought from your local dealer or online.

Fuel Mixture Ratio Is it - 25:1 40:1 50:1


not sure if yo are changing the jets out but if your using the original screws and jets screw both screws in till they stop then turn 1 and a half turns out they try starting if it kicks and won't run then turn each screw another 1/2 turn out try starting if it runs rough adjust the gas jet a little bit till it runs smooth once it warms up give it full gas and you should get just a slight puff of black smoke to be set right, if it's too lean it will get hot and will be hard to start if it dies, if that happens then give it extra gas. once warmed up it should idle without dyeing if it dies adjust the idle screw up 1/4 turn at a time till it runs at idle without holding the gas trigger, be sure you replace the in line fuel filter and fuel line first then clean the air filter before doing any adjustments. most problems are caused by plugged fuel filter due to ethanol in the gas.

It should start to run again. This means that the gas cap is clogged up with dirt. It is not vented properly, causing the carburetor to not get gas.
