Help identify these older McCulloch’s

[mopar4u]

Grab these today from someone getting ready to scrap them. I cant find a model #. They are big and beefy. Im gonna clean them up and try to get going. Both engines are free. What model are they and do they have value?

Looks liked one of them is a 250. Probably are both 80cc saws.

The air filter cover looks like the one on my 1-50 but the oil tank is in a different spot.

One of them is a 250, flip the other one over and look for the model number stamped on the bottom of the crankcase.

There were several editions of the 250, early ones had thick rings and a long yellow AF cover that went over the oil tank, later were thin ring and had the shorter black AF cover like the one shown in your photos. The thin ring saws were very good performers.

As Mark said flip them over and look at the bottom

Here is the other one. Looks like a 1-42

So the other is not a super 250?

What is the difference between the 250 and 1-42?

 

[heimannm]

Same bore & stroke and many parts will interchange but the 1-42 does not have bearings in the piston and does have a removeable head.

One is a 250 and the other one is a 1-41. Turn it over and look for the stamp. I believe the gas tank cover with the two ridges I've only seen on a 1-41. Here's one I've been playing with (for 2 years!) but haven't been able to keep it running consistently. I believe the seals on the L H jets are leaking. But I've just tinkered with it every now and then and then put it back on the shelf...one day...

The stamp on the crankcase of the OP's saw is 1-42. McCulloch was pretty good about using whatever parts were handy when assembling saws.

A Super 250 has a longer stoke (1.500 vs 1.375") and much better porting. A different saw altogether.
