I was unaware that Mac rolled some of these off the line with an automatic oiler.

The 740, 790, 795, and 797 all had the impulse oil pumps mounted on the oil tank. The 1-7X saws did not have the automatic oilers.

640? No locating pins on that one, should be more like 0.012 on the wide side, small as 0.006 is probably O.K.

Thank you sir, looks like I'll be ordering up a set of rings for it soon.

I took a break from my 125 to tear into the SP81, a split recoil pulley was responsible for the "locked up" state I bought it in. A teardown and cleaning was in order, after some scrubbing and scraping all the carbon out of the muffler I was ready to do a p/v test, spark test, and then begin re-assembly! The pile of carbon in the one pic is about 1/4 inch tall, but somehow the spark screen wasn't even slightly plugged.

Sign of a real mechanic is when Band-Aid is as dirty as everything else.

I have no photos or videos to document it, but my Mc 101 and Mc 40 kart powered saws both ran over the weekend at the Badger Steam and Gas power show.



Thank you again to Luke and Parker for solving the carburetion issues on both saws. Hopefully someone there captured some photos and videos as my phone/camera battery ran down during the gear drive saws.

I had a visitor this week, some of you may have heard of Max the Mac Man.



We traded a few parts, conducted some technical sessions, Max recorded a video, rearranged some equipment in the display (to accommodate the Titan Blue Streak), and even had a few meals.

Max donated this large promotional banner and we put it up in hallway.

I was able to swing by Baraboo on my way back from picking a wood shaper up for dad. Didn't get but 15 minutes in the saw area as we had our daughter and it was hot out. Still was neat seeing a few saws run and the collections. Here's your video Mark.

 

[heimannm]

Thanks for the video Scott. The 77 ran pretty well once I got it cleared out. Chris's 3100 was untouchable... In the interest of seeing some different saws, past winners were not eligible for awards.

[heimannm]

The 55 did well in the 5 in3 and under gear drive group, Scott BP-1 ran exceptionally well. Mine was out of fuel...

Bobby Framke and his nephew Geoff demonstrated what a 1-10 could do with a little attention to details for the 60cc and under group.





They said I cut out with my PM55 but I think it was just so fast they couldn't see the cookies falling.

[heimannm]

The 5 in3 and under group had quite a few saws. McCulloch was well represented, and Alvin Fink's 7-10 upstaged a number of larger displacement saws.

Looks like the MAC 800 took the numbers on that one.

 

[heimannm]

Past winners were not eligible for awards...and technically the PM800 should not be competing as a vintage saw; only saws in production in 1979 meet the criteria.

To make things fair for the over 5 in3 saws the SP125's run by themselves. Bobby Framke's 550 was not far behind the Husqvarna 2100. My phone battery died during the under 5 group so I didn't get any photos of the big saws or hot saws.

Even Mini Mac saws can be winners.

7-10 are great saws , all ways fun to wind them up ,

 

[duwem]

That Mike D guy needs to learn to make straight cuts so he doesn't end up having to make an addition cut compared to everyone else

 

[heimannm]

Mike D should come to Iowa and practice his chainsaws technique...that way he'd get practice and I'd get firewood...
