What model mcculloch??

[tigerrider11]

I just got this older Mcculloch. From some quick research I'm thinking its a 5-10, but I want your opinion.
What do you think it is?

 

[bob15]

Could be a 5-10, 6-10 or even a 10-10.

What does the serial tag show for numbers?

Best guess is a 5-10, it was the only one of the basic 10 Series to have that style of compression release.

The same mechanism was used on the CP70 and the "E" battery/electric start models.

Of course as with most McCulloch saws, it could be a frankensaw of some sort but it looks to be pretty original.

I differ to Jedi Mark, but I repped you for the McC logo gas cap. Haven't seen that before.

The red on/off switch is from an E-start Mac 10. It does not lock the compression release in place. On the E-start models, pressing the button down engaged the starter switch and opened the CR. The handle also has the hole for the throttle lock, which was used on several different models. I't probably a mutt. Don't lose any sleep over it. If it runs, cut with it. It does appear to have the wide flywheel cover, which would indicate it may have originally been an E-start model. The extra screw in the strap that runs from the handle to under the saw also is a clue to a 70cc saw, which could mean it is a 5-10E. The plastic plugs in the tank assy are indicators that it had a Walbro carb conversion kit installed to replace the original Mac "bullfrog" carb. I just picked up one of those conversion kits on Evil bay .

Not meaning to disrail your thread, but does the clutch stick out enough to fill that cup on the clutch cover? Just curious as I know nothing about Mac's.

yep, outboard clutch, complete with starter pawls

Most of that space is for the starter pulley.

A 6-10 and one 10-10 series also had that style de-compression button.

The clutch cover looks like its an "E" model (the picture shows it looking wider than a non-E start saw, at least to me), but no battery pack on the lower part of the handle. Not saying it couldn't be a mongrel saw (I've made a few myself.....).

Bob - are you in fact referring to the flywheel cover on the left hand side of the saw? It does indeed look to be from an electric start model, as does the red starter/compression release button.

Charles - lookinig through some additional IPL's and photo's I see that there was a 3-10 DSP (fact is I have one, forgot about the compression release on that one) and that some 6-10 models had the compression release valve above the muffler like that one. May be some other models as well, I haven't studied all of them in great detail.

The air filter cover is more like my older 1-10, not like the 3-10E or 3-10 DSP that I have.

To the OP, remove the muffler and put a wire through the exhaust port to measure the bore to determine if it is a 50 cc or 70 cc version.

I took a quick look at it before work the other day and the only numbers I found were right on the bottom of the block: 1057
I will do the wire trick to determine the bore tomorrow...

Use something that won't scratch the bore to do your measuring. Popsicle sticks work well (but don't always fit through the ex port). Plastic straws and stiff coper wire works well too. Improvise....

 

[tigerrider11]

Here are some more pics of the same saw... still haven't measured the bore, but it seems like there could have been a battery pack in place at one time... the exact model is still a mystery as the tag behind the carb is missing. dont pay attention to the carb as its new to the saw...
one this that might lead to this saw's identification is the air cleaner cover... it has a smooth top surface, long sides, and only 3 vent slots on each side in the rear... hmmm

 

[tigerrider11]

and the rest of the pics...

My 3-10E and 5-10E have different tanks and AF covers than the saw you show.

Yours may have been an 10-10E, or could be something else altogether put together from all the left over parts in someone pile.

I'd say it looks like a 10-10E, though mebbe a frankenstein one. Will be a good runner.
