Mall Model 5

[bplust]

Hi all,

I picked this rig up two years ago, and finally got it unstuck three nights ago after adding penetrating oil to the combustion chamber on a weekly basis. 200cc's... it's a big one.

holy crap!!!!
that is a beast
the chain probably weighs more than my MS261

And here's where I'm at right now, I am pretty concerned about how choked the exhaust is :

 

[bplust]

The transmission weighs over 12 pounds....

dual port and a HD2 and it will probably just start itself

funky piston and assymetrical exhaust system, there is some old school amazing cool in that bad boy

nice project!!

 

[bplust]

It's an old one. It turned 72 years young this year.

 

[bplust]

If anyone was wondering, the cable coming up from the stator is for ignition advance/retard.

Sure is, Randy. No bicyclists were harmed in the transport of this saw.

Now make that monster blow some smoke, stop teasing!

That is a monster. We're there saws made larger than 200 cc? What do you think it is going to take to get it running?

Very very nice looking Model 5 - that will be a great original machine when you have finished with it!

Yes, there were much larger machines than 200cc's.

Regarding getting it running, it needs the normal stuff (seals, fuel line, carb work, ignition work) and the top two rings are frozen.

Nice Bryan. That one would be fun to work on.

Thank you, Chris. I was very fortunate to find one, especially in this condition. The fuel tank is in excellent condition, and beyond a little welding on the handlebars and a tiny bit of chain rash on the transmission, there is nothing cracked or broken on the saw.

I just pulled the jug an hour ago. I knew it'd be closed port due to the external transfer caps, but I was very surprised to find a single piece rod and a full round crank. I will admit that I'm a newbie to saws of this vintage; case and point, I used #5 starter cord as a piston stop for removing the flywheel and clutch. It took 11 feet of cord to finally stop the piston...

so much different from normal saws I didn't even notice the three rings

If you look closely at the shot of the piston with the tape measure, you can see that in lieu of locating pins, when machining the ring groove, they left a bit of meat in the groove the locate the ring ends. Pretty cool stuff.

and then there is the shape of the top of the piston
