Hi and welcome to FixYa. I am Kelly

You are going to have to rebuild your carb and get a

GASKET & DIAPHRAGM KIT

  • TILLOTSON DG-2HL/DG-5HL
  • Fits all HL model carburetors
One of your many diaphragms or gaskets is leaking even though it is clean all it takes is a pin hole to cause havoc!

US source for the same kit:

Make sure to download this 8 page manual to help you with the carb repairs:
http://www.tillotson.ie/docs/techinfo_HL_US.pdf

Just make sure you have good fuel flow to the carb fuel inlet from the gas tank with a good rate of flow.
When you finish it will work great if you did it properly. You will for sure have to adjust the fuel mixture screws after the re-build.
Thanks for choosing FixYa,
Kelly

SOURCE: not getting spark when starting

[email protected] HI GRYDERT your problem could be your on, off switch. This might sound funny, but switch the on off switch real fast several times, then see if you havee fire. If not check your spark plug. If you have a n
ew one try it. If that don't work check the connection at the plug to be sure it is makiong contact with the plug. If all this does't work you will have to go inside to the coil. They don't usually go ba d but it could. But first check to be sure it isn't grounded at the small wire from the switch. Good Luck.

SOURCE: hi,my stihl ts 410 saw

Sounds like an overheating problem.
Are you working in a well-ventilated area or in direct sunlight?
Check, if you can, the temperature of the motor case.
You might have to take a break more often.
This hot summer has stressed a lot of motors and electronics.
When it shuts off you know it is trying to save itself from burnout.

Stihl ts400 quick cut won't draw fuel. New carb installed same problem exists. I am now getting beyond frustrated. It will start and run for a moment on carb cleaner but when its out of carb cleaner i

Check the boot between the carb and the cylinder, it could be an air leak. also check the compression. If the piston rings are damaged then it wont have the compression to pull the fuel through. Could also be a damaged fuel line, or plugged filter.

Stihl ts 400 has stopped working and sounds rough when pulling the cord

Sounds bad, the only answer here is to pull the cylinder off and check the condition of the internals, if there is a lot of dust behind the filter and into the back of the carb the engine is going to be in need of rebuild.

Stihl ts 400 wont start

If there is good fuel in the tank and the plug gets wet with fuel, and there is a good spark stating the obvious it should go, if not there could be a mechanical issue, piston scored, rings worn etc,

First my Stihl Quikcut was getting too much gas now after rebuilding the carb it's not getting enough

Not sure who told you about the compression but that is not true, are you sure the throttle rod is actually pushing the throttle shaft open?

My Brand new Stihl ts420 cut saw wont run full throtle, smokes white, and leaks fuel out of exhaust filter. it runs like the choke is half on.

This sounds like the carb is flooding, there is a rubber tipped needle under the metering side of the carb, this may be leaking, before replacing the needle make sure the air filter is not blocked, replace with a new filter and try again

Need to know belt size fo the stihl ts400 concrete cutoff saw

You should go to a Stihl dealer and ask for the belt for a TS 400 Cut Off Saw. The belt is ribbed, you should only put on a Stihl part to replace the belt and make sure the belt is under the correct tension. When you go to the Stihl dealer you can ask them to show you how to make sure the belt is under the correct amount of tension.

STIHL TS 400 won't start

I just repaired one with a similar problem--not getting enough gas. Two things corrected it and both were carb related. First I replaced a rather stiff diaphragm with a new one and second I reset the intake valve to allow more fuel into the carb. That solved it. Good luck.

The gas filter is weighted and should remain at the low point in the tank so it is an issue only when you are about to run out of gas--unless gas has been sitting in the tank for a long time. That can leave a film on the filter that can restrict fuel flow. Pull the fuel filter from the tank and scrap lightly on the filter. You will immediately note if there is a film on it. If so, replace the fuel filter.
