Does the Dolmar 7300 jug have the same open transfers as the
6400?
Anyone run one? Adam

7300 is like the 7900 cylinder Adam. Dan aka Dozerdan has a
7300 for sale right now too.

Thank Kevin. Did the 7300 come out before the 7900? Or were
they all marketed during the same time period?

I'm only guessing. But thinking the 7300 7900 was same time
frame. I remember seeing 6400 7300 7900 together. 6400 was only
open.
Also Makita had them in 7301 7901 6401.

[quote="dozerdan"]I will take 400.00 delivered in the lower 48
for the saw with the 73cc cylinder. Add 35.00 if you want the 79
top end on it.

Thanks kev! Adam, I was thinking a 6 transfer 52mm cylinder
would be interesting for a stock appearing 5 cube. have to look
at one of my 6400 jugs and see if there's enough material to
bore that much. Adam

That is a October 2009 or later or at least has parts on it to
make it look that way?
It would be hard to beat the offer of $435 for the 7900 cylinder
on it.
The 52mm big bore doesn't have more power than a 7900 unless you
port it?

Sounds like he's thinking of boring the cylinder out to 52mm.
