I saw this interesting Mac 10-10 auto (pic 1) in the online classifieds today. It's got one of those one-piece starter covers that I've seen posted here (and also in the Mac workshop manual), but it's covered by a sort of mesh. It looks like a home-made setup, but I've actually seen one just like this in the classifieds before (see pic 2 below).

Both have the smooth black fuel tank top and air filter cover, as opposed to the irregular "stone chip" kind finish on the other one in #1, as well as my own. Has anyone seen one like this before?

I have seen pics of European MACS (Belgium) with the screen added.

I got what I think is the impulse line (short black rubber line) between the tank, and into the engine. It's pretty old and looks not in the best condition. While I got the saw in pieces I thought better to replace this line. Can I use one for a Stihl saw, or did McCulloch use a different size/dia? Can't really find any online...TIA

The ones with the steel sleeve could be bored oversize (McCulloch offered 0.010'", 0.020", and 0.030" oversized pistons for the saws with the sleeve). Some would ague that the chrome bore were a bit smoother/slicker and would allow the engine to run higher RPM. If the chrome is damaged it will be necessary to find a place that can clean up the bore and re-plate the cylinder.

Thank you. I thought that was the difference in the S or C destinations on the saws. Just not as up on the 125's I assume US chrome could rechrome a 125c block like they have some of my 82cc 10 series blocks. Again Thanks. I try no to bother you guys with dumb questions lol. This is what happens when yellow fever expands outside of the 82cc 10 series realm. Long sorry short I may have found me a 125C. Like I need more saws lol.
