Got the 371 home, and here is what I found:

Didn't expect to find limiters on the carb, guess someone spent a couple bucks on it. The cylinder and piston look very good to me. Guess I didn't have enough light to see the 2nd ring earlier. Mahle made the orginal cylinder? or is this AM?

Hmm interesting. I had a 371 parts saw that had no limiters on the carb. Should be a mahle cylinder.
I thought MOST 371's had a single ring piston. And orange air filter cover clips.
Looks like a real nice saw though!

Mahle is OEM but the original Mahle 371 cylinder had two top fin corner notches on the front instead of one.

Spark plug was VERY wet and piston has wet carbon on top. Fuel was nasty looking and dumped. Broke the connector off the end of the plug wire getting it off (think it was in bad shape before I man handled it). All of these things may explain why it had a major bog off idle.

That's in really nice shape!
This is a pretty good thread on 371's:

It has a Walbro 12a carb on it.

So you think this cylinder has been replaced? May explain the machining marks being so pristine. Maybe the carb got replaced with the P&C?

My 371 was the same with a two ring piston and limiters on the carb. It also has the black filter cover clips. I think it has something to do with the last year of production before they started making 372s.

The limiters can be removed with a wood screw, can't they?

I've always just trimmed off the tabs/stops with an x-acto knife.

Yeah, me too. Or a flat file works pretty quick too.

Mine had one ring and also had the HD-6 carb on it have to look to see the production date.

EPA version, looks to be all OEM. Good saw Sold mine and kept my red and black 371.

Will this have a limited coil? How do I tell the difference?

 

[decableguy2000]

I believe the limited coil is blue and unlimited is black

 

[rattler362]

I don't think so mine is a early saw it is not limited.

Two rings and carb limiters just means it is the EPA version.
