You need that 2/55 A/C. 2 windows down, 55mph.

I have an Echo twin-cylinder CST-610 that I'm desperate to get running. I found an issue with the original coil, but I think I had already damaged it otherwise before finding the loose connection at the ground to the laminations. The first picture is the resistance from the kill wire to the...

I read somewhere that supposedly red is the coolest color, since it reflects more of the infrared spectrum.

Did you heat it? If you're replacing the seal anyway you don't have much to lose.

Yes.

That pump diaphragm is incorrect. It should be solid instead of having the large cut-out on top. Usually there are more than one kind that come in the kits so the kits work on more models.

You could say "level with the floor of the metering chamber"

No, I meant the pump diaphragm. If there is a perforation in the pulse chamber area, it will leak into the crankcase. That's not very likely except with the thin plastic style diaphragm.

It fires every other upstroke, just like a regular 4-cycle engine. The mix part means it takes mixed fuel. That's how they get the name.

As far as I know, the seats are not available as a separate repair item. When I need one, I punch one out of an old carburetor and install it at the same depth.

I would suspect that the carburetor is leaking through. Do you have the tools to pressure test the carburetor? If you changed the needle, sometimes a new needle seals worse than an old one if the seat is worn. I just had a MS260 that had a pitted/corroded seat (despite being chrome or stainless...

Ok sounds good.

That makes sense, and is what I would have said if I hadn't read this on Stihl's site.

Not to be too contrary, but as a lawn mower shop we hate tubed tires. Tubeless tires are so easy to plug a hole and go. I've never seen grass jammed in a rear tire bead that had decent pressure in it. Maybe you should get Tweels ;) , if you can stand the price.

I can't recommend oil that biodegrades 80% within 21 days of being mixed with fuel.
