First off I'm sorry if this is posted in the wrong place. If not allowed here feel free to move it or delete.
So this weekends score made me happier then any in recent memory. I was contacted my a logger who had a pile of Dolmar 7910 saws and a bunch of parts.
While I was there I was also able to purchase a Stihl 462C very cheap but it needs a new clutch side case and that's a whole different ball of wax.
Alright, back on topic here...
I've been sifting through all the parts and trying to pick out the better of the parts to build myself a saw to keep and the rest I'll assemble and sell finished and running or as is for projects.
I've already noticed that there is a difference in the pistons and cylinder. I never knew there was different variations of 7910 cylinder or what is going on here?? I have 4 cylinders and they are all the same bore size and all have the decomp in the top and the weird SLR channel in the exhaust ports.
I have 2 that the upper transfers are very close to being inline with the intake ports and the other 2 the transfers aren't as wide but the exhaust port on those look a little bigger.
so which is the better just to start with? The wider transfers and smaller exhaust port or the narrower transfers?
Thank you guys for any advice you can offer
