What's the difference between the two?  Are ignition and carbs the same ?  I want to put a52 mm big bore on one.

365's came in open port /  closed port . I have seen walbro and zama carbs used.  The walbro is preferred, but I used what I had on hand, zama's on stock and ported and you wouldnt have known it unless I told ya.    Blue coils limited to 13.5K, black coils unlimited.

You can put 362 365 372 50mm , 372 51.4mm,  plus 52mm BB afm on them.

Was there a issue with 365 and a week case by the bar?  If so what years were effected and was it a major issue.

The open port 365 had a bolt-on intake boot. The was a bolt on flange plate that retained the boot.

The "so called" weaker crankcase by the bar mount involved a couple webs inside the oil tank that were later added to 372's

Unless you are jerking on a saw with a hung up bar, I doubt it would make any difference.

Had one of what I believe may be a older 365. The recoil decal just had 365 on bottom part.
Guy said he bought it new.

Dont have to pull cyl but maybe there is other tells that might tell me open port by the transfers.

Plain 365's had zama carb, non adjustable oil pump and front chain tensioner
365 special had walbro carb adjustable oil pump and side mount tensioner in the cover.
 Early plain 365's also had an oval inlet manifold/port and later changed to round before the 365 special came along.

I have four 365's but they are all "Specials" and little different from a 372XP

One of them has a Zama carburetor but who knows why it is on a 15 year old saw?

I've run Zamas on 362,365, & 372XP's and cannot tell any difference in the way the same saw runs with a Walbro. The Walbro has a bigger venturi.

The only difference between the special and 372 is the cylinder/piston. 48mm v 50mm

A special wouldn't have had a zama from the factory unless its an early one maybe and maybe they wanted to use a few up maybe tho ive never seen one.
The walbro is meant to be slightly better and appears to be the case.

Ive heard some people upgrading to 372/big bore and the zama struggles slightly whereas walbros seem easier to tune and 4 stroke easier.
Ive had similar on 357xps with the zamas they don't always appear to overfuel well and allow a 4 stroke compared to walbros even thp they where opposite and started with walbros first then went to zamas.
