tilt and stop

[ned coed]

this is'nt a chainsaw problem but thought this would be the place for some help. it's my brothers sthil ts 400 disc cutter. it runs ok until you tilt it forward then it stops. i can't say iv'e ever had this before on any saw. has anyone out there had this problem before. help much appreciated.

The 051 did this once and I found the fuel filter was hung up in the rear of the tank so when the fuel sloshed foreward the filter was high and dry.

A contest

Ok guys, I will P.M. Ned what the problem likely is. It is a known problem.

The first one to correctly figure out the problem, gets the prize.

Broken torsion spring on the shutdown rod

I told Ned to check it out, and let the forum know if I was wrong or not,
but not give it away until someone came up with the answer..........

It is getting too much fuel

My guess with help from Tim's Tips. (Tim Ard)

4. Roll-over Test - Let the saw idle for 10-20 seconds and then turn the saw to different positions.
If the saw stalls, it is getting too much fuel, which is puddling below the cylinder. Turn the low speed
screw clockwise (reducing the fuel) a little bit and repeat the test.

This is a concrete/cutoff saw....

4. Roll-over Test - With the chain brake engaged, let the saw idle for 10-20 seconds and then turn
the saw to different positions. If the saw stalls, it is getting too much fuel, which is puddling below
the cylinder. Turn the low speed screw clockwise (reducing the fuel) a little bit and repeat the test.

So does that mean it's fitted with disc brakes :monkey:

These are complete shots in the dark.

Broken carburator boot

Bad crank seal

bare/skinned kill switch wire

This one is the most correct answer anyone can give

it's a Stihl.

:monkey: Am I missing something here? Wasn't Fish going to give you the sacred knowledge in the first place?

1. Check tank vent 2. check carb needle for bad wear 3. check crank seals on clutch side. Could also be a pinhole leak in a fuel line or carb boot and when it gets stretched it leats air in.

please end the suspense... What is it??????

 

[icelation8]

ignition/killswitch wire wearing into crankcase?

Well, I sent him a p.m. right after my first response, but he is new here.

Or I may have screwed up, that is very possible.

I have worked on half a dozen of these saws with squirrelly problems like
this, and all of them had the insulation cracked off/rubbed off.

All other suggesstions were good ones. I sent the p.m. to Ned, for him to
check it out, and get back with the results...........

Oh well, I meant well.

Space, you have been on track with your guesses here lately, that is, if
that was/is the problem.

icelation you too.

Let us know Ned...

I know what you mean about the sheathing on the earth/ground wire. I've worked on quite a few myself and they are pretty much all like that. What I don't understand is the wire wears as it is touching the inside of the plastic shroud and obviously the vibrations of the motor cause the damage. What I don't understand is how this could cause the symptom Ned describes?

There is nothing for the bare wire to ground on where it is and I don't see how a change of position, tilting the saw forward, is going to make it contact on anything?

Or maybe I'm misunderstanding you???
