OEM NOS 52mm PS-7900 P&C kit

CORRECTION/Edit:
This is a as new takeoff 47mm PS-6400 P&C kit.
My apologies for the misinformation, I thought it is the 52mm I have "somewhere" (I'll find it, but not tonight)!

Marked with Dolmar logo on one side and "MAHLE" brand on the other.

Is that number 477D09 ? If so I will add it to a cylinder number file.

To be fair @ErnieG picked up this cylinder super cheap knowing it probably was am. Also seller probably had an idea it was not OEM or he would have asked oem price for it

If the kit was priced correctly for an AM no harm done.

I bought one not ever wanting to have to utilize it!

Yes I did get it cheap and I was certain it was an aftermarket but was hoping I was wrong but I'm think not .
Seller never mentioned anything in the listing about it being an AM and I even sent a message and asked but never got a reply yet and it was shipped...so we'll see what happens when it arrives .
Maybe I'll have to open a claim if I don't get a reply to my message!

A little muffler mod action I don't like trying to get the flange back in there 2 6mm nuts works nice

Also for you dolmar fans. Broken 7900 oil gear makes a pretty good replacement oil gear for a 460.

Here's a scan of the 7900 spike set! Figure someone might want to get some cut out

Also awaiting a 5100s in the mail! Snagged a 'burned up' one for $120, and a nice piston/cylinder kit for $40. Budget beast of a saw

I plan to uncrimp the muffler, and gut the internals, as well as a retune of the carb. Sounds like these saws were often set too lean? Where do y'all like to tach a 5100?

Any other common performance modifications done to this saw? Gasket deletes, timing advance, or grinding the transfers for flow?
