I'm probably not ready and able to shed light into this issue, first becase I don't know the internals and second I wouldn't finish in reasonable time...
When Makita bought DOLMAR in 1991 from its previous owner Fichtel & Sachs AG which in turn at that time belonged to Mannesmann AG, DOLMAR remained a more or less independant company only then owned by Makita. They kept their product range just changing the branding from SACHS-DOLMAR back to DOLMAR as it had been until mid 70s.
DOLMAR not only kept and continued its product line but its engineering facilities as well and continued to develop new products.
There have been efforts by Makita to migrate DOLMAR products into Makita directions, e.g. DOLMAR built a couple of saws in Makita colour but still DOLMAR branded that were given to dealers to expose them and test customer approval. That probably didn't turn out to well otherwise DOLMAR saws would have carried Makita teal from then on.
About that time however DOLMAR chainsaws were introduced with Makita branding and Makita colour scheme as Makita DCS-models in parallel to the DOLMAR line but were sold through different dealer networks.
However next to none original Makita products turned up in DOLMAR branding, there are no DOLMAR electric drills or circular saws. Instead more other product lines appeared with the DOLMAR brand like a line of home and gardening equipment, next to none of them developed nor manufactured by DOLMAR but badge-engineered by other companies (not necessarily Makita subsidiaries).
In retrospect it doesn't look like Makita had a long term strategy of what to do with their Dolmar subsidiary, whether to place it as a supplier for professional forestry equipment (of what DOLMAR had a long and strong history) or for home and garden machinery. Neither path was seemingly pursued consequently...
After repeatedly showing losses Makita pulled the line and extinguished DOLMAR as a self-dependant company and integrated it more closely into Makita hierarchy, naming it now "Makita Engineering Germany" thus reflecting to what had become a main purpose of the Hamburg, Germany based DOLMAR factory: A corporate wide supply of production lines.
Distribution of DOLMAR products now was handled by Makita, official manufacturer no longer was "Dolmar GmbH, Hamburg, Germany" but "Makita ... Belgium". In other markets things seem to even more confusing: In US for example, the DOLMAR brand was replaced by a new Makity product line with tangerine (aka DOLMAR coloured) machine bodies but Makita branding.
But this all was topped by Makita's decision late 2020 to stop production and sales of petrol powered equipment in march 2022.

Just my 2 pence, many of the information and opinions I cannot document since it mostly derived of personal contacts and talks with (ex) DOLMAR dealers and employees.

Wow! That's a lot more detailed than my post. Thanks for the information and effort!

I will treasure this Pic for as long as I live and I still have the saw in my garage:
View attachment 387680
I take it out occasionally, and it always starts and always runs with the 32" bar as shown. I need to operate it more often and likely I will this year when the current heat wave subsides.
She can handle 36" easily, and YES You need to grant her more playtime!

This is my family. 4300, 5030, 6100, 7901.

These are the only saws I have left after owning probably over 60 runners at one time. These four will be around indefinitely.

Good evening fellas. A while back I snagged a box-o-6410 parts…and then I snagged a good used 7310 cylinder for cheap. Since I don’t have a piston for the 50mm top end, I was wondering about possible piston swap options. The 79xx pistons and I assume the 73xx have a pretty narrow skirt and limit exhaust port width…would be nice to find something that would offer more wiggle room.

Just get the AM 50mm piston kit and a Caber piston ring from HLSupply and go from there! ;)

I was looking through the meteor catalog this morning I think guys sometimes use 046 pistons in the 7900? So maybe you could use 044 in 7300? Do you know the wrist pin to crown height on a 7300 piston?

I don't know off-hand. I can get a measurement next time I'm in the shop. I compared a 372xp slug with a 7910 slug, and the 372 was probably close to 0.100" taller than the 7910.

That will work, but I believe you need to run the piston backwards to keep the ring ends out of the transfers.
