MS201T Curiosity

[ZeroJunk]

Well, they dropped it out of a tree or ran over it. Whatever. My partner in crime put a new handle on it. And, it does not want to run correctly. New solenoid, new carb, same thing.

Here is the weird part. You can set in on the mat on the floor in the triangle position and it will sound normal , but when you pick it up it revs up and cuts off. Even if you do it with just your thumb and index finger, never touching the trigger.

One would think if it is some incorrect mounting of the linkage that it would just rev up like you were pulling the trigger. Curious.

It is all back apart now and he is going to put a new ignition on it.

If we are not good at anything else we can throw money at something LOL.

Wiring harness may have a short
impulse line and or air boot ripped or not installed correctly

And look at the linkage again, too.

I pressure tested the impulse and the intake looks perfect.

I did not take the cover off the linkage , not sure you could even get it on with the linkage wrong. But, who knows.

The wiring harness losing signal to the solenoid is certainly plausible.
Not sure whether he replaced the complete handle with harness or just the shell.

Well, look close at the wires for breaks or pulls. Were used, or new linkage put back in when the handle was replaced?

I don't know. I'll see what he did Tuesday. I just work Tuesdays and Thursdays. At 69 that's enough.

I know what you mean, buddy.

Sounds like you are working on an MS201TC, not 201T?

Yes.

Well, I guess sometimes you have to admit you are just dumb as a stick of wood. It was a crack in the manifold.
My vision works about half way like other things these days.

I had one with similar issue. Turned out to be a severed wire…inside the wire’s casing so it looked fine. Replaced the harness…solved.
the wires had tested fine initially as the break would get contact in one position but not another.
