Newest addition 241c-m

Yeah, this poor thing is acting like she's rich at idle. It got worse after porting. And the weather has gotten warmer, which has made it even worse. I checked the plug after she died last and pow - wet. SO gonna try the metering. Hopefully that fixes the idle and the bog. I have a feeling having to play around with the set screw on the butterflies is gonna be a pain.

Which way on the metering lever for less fuel? Down?

 

[wyk]

Yes. I'll play with her tomorrow and see if I can get it right with the first few tries.

Judging by the amount of carbon built up in this thing, she was running rich long before I got her.

OK...so... anyone know where I can get a new diaphram for this carb?

Gonna go into the IPL and see what the local stihl guy wants to rape me for. But I suspect the part is the same for pre mtronic...

Hah, Walbro calls is the "WTF" series. Nice.

So I need a diaphragm for a WTF -1/-3

The diagram has a hole in it Reindeer?

 

[KG441c]

Reindeer I was looking and the only differences I see between a mtronic carb is some linkage and a solenoid? Gaskets and diaphragm looks the same ?

I went ahead and ordered it from the local stihl rapist. He will have it in by tuesday. Says I am the first person to have ordered parts for an MTronic carb - including themselves. So wish me luck on them arriving and being correct. Do not ask me how much it will cost. I don't want to repeat it. But the cost of shipping from the states and potential down time makes it worth it.

Yes, it should sit level though to be correct.

Checked the stock compression on my 241c again just to double check my reading again. 172psi

What's your altitude?

Ah. I am at 50 or so depending where I am on the estate, and the air is always cold and dense here.

My adapter should be here any day now.

About the same here. Been 'warm' lately. We're in a valley, so the weather is usually tame, even by Irish standards.
