Yeah... and then you got someone selling a S44 that is labeled as having a kart engine in it. I don't remember what it went for, but it did go for more than a good parts saw should. It was just a good parts saw...

Actually, the 44/55 Series saws were pretty close to the kart engines of the day. Both were high revving (in comparitive terms) high performance engines. Last year at Barbaoo, WI my bone stock 55 with 9/16" pitch chain finished third in the gear drive class behind a Homelite 1100G and my McCulloch 77 (at 120 cc's).
The D-44/55 were only 72 cc's but they were equipped with an attitude.
The S44/S55 were 80 cc's, and the Super 444/Super 55A 87 cc's. Find one with good compression and be ready to be surprised.

Is it true that a kart head can be fitted to increase compression yet further? IIRC, one of the earlier kart heads will fit.
Nice surprise
In addition to CAD, I think I also suffer from CADD. I started to put in a little more time assembly time on my rebuilt 800 tonight but got distracted with my eBay Frankensaw. It just kept calling me to come over and look at it. Long story short, it turns out that a previous owner had only replaced the flywheel and the flywheel cover (early style). The crank was the new style so all I needed to do was replace the flywheel and cover. A previous owner had also stripped out all of the upper shroud threads but there were enough attachment points left that I was able to fit a borrowed cover on it and check the compression. It hit 170 p.s.i. before I quit. It may have a few more in it but I didn't want to break anything. That is good enough for me as it is 5 p.s.i. more than any of my other q-port saws. I was a little curious about the saw as the crankcase is black (my others are either yellow or grey) so I check the model number. If the tank is original to the saw then it is a PM805. Now I just need to find a reasonable priced upper shroud. With the news on the crank, I can use the crank I bought for it on the DE80 I picked up as a part saw. I just need to find a DE80 tank and I should be good to go getting four more 82cc MACs in running order. If the hot weather keeps coming maybe I can get done before cutting season. I only have left to rebuild a kart saw and 2 82cc saws; assemble another kart saw, 2 other 82cc saws and 1 SP70; and fix a 125C, 2 PM6As and a SP40 - then all my saws will be runners with the sole exception of my grandfather's bow saw when froze up sometime since I parked it after my accident 30 years ago - maybe that can be a winter project. If I can average one saw a week (and don't buy any more) I'll make it. Ron

Sounds like you will still be pretty busy for a while Ron. I am not sure I even remember which saws were apart when I left home...

My entire 12 week one a week program could be condensed by you into a good day's work, Mark. I admire you and the others here that just seem to knock them out whereas I tend to gather parts and thoughts. Ron

Finally, the welsh plugs got here and have been installed. Then sealed with 1194.
So... since all of the gaskets are now made (I think so anyways, if I missed one along the way, I'll make it) and all of the parts are in other than bar plates, the 790 will likely be completely assembled tonight...
Might borrow the bar plates off of the 250 to make some cuts...
But I shouldn't get ahead of myself here... that flatback might not work... only way to tell is clean it, put the kit in, and see if the 790 will run. I've got an emergency Tilly on standby, so if the flatback refuses to work, then the Tilly will get cleaned up and installed.

I may have to start working nights if this heat doesn't let up...97 today and tomorrow..

Pfft... 98 here, heat index of 103.
Outside all day... mainly running around to get those stinking welsh plugs... No a/c in the Ranger. Not that I need it...
Then go work in the barn with the window a/c in the office (like a small building within the barn) is running and then it's about 110 give or take inside that barn where I work.
Yay! Heat!
In any case, the 790 will be mostly (hopefully completely) assembled...
Kind of a hobby for me, really doesn't have to be done. Surely it's gonna cool down some time. Son says I should put A/C in my shop. I can get a used one cheap but I like to work in there with all the doors open so I'll wait some more. I just got some parts in to fix one of my saws but that building has to be 120 in there right now.

Sorry to hear that guys. It's a whopping 80 here and they expect thunder showers by tonight. Big cool down once the marine air drifts in. Got my friend's mm-6 running on Sunday. That thing is way loud for a little sucker. It runs but pulls chain lube into the crankcase. :msp_sad: smokes up the neighborhood real good.

Seems like we haven't had 80 degree weather since January!

Joeymt, finally got to look at the saws Sunday, Thank you, they look super clean. I just looked at them and said, screw it, it's too damn hot outside, I'll wait until it gets into the low 80's, or at least wait until the humidity goes down some.

57 and raining.
Been sorting through all the saw stuff, need to condense all the loose stuff into 3 or 4 boxes. I have a week or so to decide what goes and two weeks to dispose of what is left. Annie says some of the saws can live in the house until we get a shop/shed.

Did a search and couldn't find the pic I was looking for...
I'm trying to find a reference photo of the points/side cover bolt arrangement as the IPL utterly confuses me. I can't make out the individual parts either.
Also, a coil from a 1-43 will work on a 790, right?

Kyle, they look a little strange to me but are these the plates you need? MCCULLOCH CHAINSAW 125 795 895 GUIDE PLATE STBX635 | eBay Ron

I am not sure, to be honest. They look quite similar. Problem is, do they come in sets of two, inside and outside plates?
What about the inside plate? This one doesn't look like it'll work properly to help seal the oiler hole on the bar to the oiling slot on the saw housing since it appears to be an outside plate.
You'll get them done Ron. I have faith.
I have had many on my plate at the same time and i
do now as a matter of fact. Just not enough time to
get them all done. I just keep plugging away at the
ones i want done. When i start one i'm on a mission
to get it done. Sometimes i run into a road block and
have to wait a bit to finish. But it's all good.

This one is the inner plate for the big Mac geardrives.
840,890,895 and probably many other models. At least
thats what it looks like to me.
