stihl ms200t throttle problems

If the rear AV in particular fails then the handle lifts too high and stresses the inlet manifold, impulse tube and fuel line.

Ah, the old impulse line coming off, that is one I forgot and worth a check as it will produce and air leak!

All I can say is thankyou!! You guys were spot on and with both problems.

First saw needed a new throttle trigger (the end had broken off), part has been ordered.

Second saw with running problems - air leak. Took the saw apart and the fix was simple. The impulse line had come off from the engine end. I presume this had happened due to the rear Av mount being totally buggered.

I'm not very technically minded and really appreciated your help with this.

I lost the will to live with my local (proffesional?) repair shops after sending saws for repair but getting them back the same with a bill aswell??

Thanks again. Avinit

Glad it got fixed, there are some good repair guys out there who care about what they do and GK and I are two of them. Unfortunately, they aren't all like us:001_rolleyes:

Another successful outcome for the team:thumb up:

 

Spud and I don't agree on everything, but between us we can usually get there.

 

From now on I am going to try to bring two words into more common use, "cause'" and "result"

 

In this case the "cause" of the fault was the AV and the "result'" was the impulse tube coming off causing the apparent "fault"

 

It is essential always not only to cure the fault, but find the cause.

Hi Barrie, i have a question for you, when a saw has been rebuilt, then test run and tuned on Aspen, it goes back to the owner who then uses it on pump fuel, do you get any returns where it needs re adjusting? not trying to be funny, just intrested if there are any issues?

If I am honest Andrew I am always mindful of the possibility, but in practice I see very few machines returned, and the ones I have had come back have never caused me any issues of trust with the customers, and have just needed a very slight tweak on the L screw to weak.

 

It seems to me that it is more often that I have to richen the mix from petrol to Aspen, than weaken it from Aspen to petrol, if that makes sense.

 

In other words a petrol machine is quite likely to need a tweak to run on Aspen, but less likely to need tweaking back to run on petrol again.

Holistic chainsaw repair. Nice.

Cause and effect, when you get a cure you can say "result ! "
