You're in luck for availability. They can be pricey so search a little deeper to find one better than $35. You could buy a whole saw for the clutch and then have extra parts.

Obviously, any other pm650 will work. So will pm610 and pm605. You could use a eager beaver 3.7 or 3.4. A timber bear clutch will work.


Any 10-series saw will do as long as it's a left hand start. 7-10, 10-10, etc.

The pro Mac saws like pm700, pm8200, pm850, pm55, pm555, pm60, etc

The super pro line like the sp80, sp81, sp60, sp70, etc

Even the cp saw like the cp55, cp70

Catching on? There are a ton of those out there.

Cobey I left you a message over in the GTG thread.

I believe the 2 starters is someones poor attempt at a conversion. It is possible to go from right hand to left hand but not the other way because most left hands don't have the keyway on the crank on the clutch side. I got a 10-10 rh but no cover and couldn't find one but had all the parts from a busted lh studied it for about a day and figured it was possible. The only difference I saw was that keyway. On a side note don't throw away 10 series parts they are pretty much universal with all that series and a few others.

What is the difference between the PM610 and PM650? According to the acres site they are both 60cc and nothing stands out as being different except the decals.

The 650 has a bigger exhaust port

 

[joeymt33]

I was just searching for pics but I can't find them right now. I posted some but they are many pages back

 

[machinisttx]

Thanks for the info, I'll have a look. Does it make a significant difference? I picked up a 650 carcass today thinking it was a 610. The engine is probably good, but the rest of the saw is pretty well smashed.

 

[joeymt33]

I've taken many 610 motors and opened up the exhaust to make it like a 650 and it's a noticeable improvement. I've also had several 650's and they run better than the standard 610.

I remember those pics now! That first one just looks fugly and unfinished. Time for me to order some burrs, need them anyway. Anything special to watch out for on the chrome plated bores?

 

[joeymt33]

Just clean up the outside, there won't be any gains if you widen the port beyond a stock 650 size. Try to stay off the chrome and keep the inside edges beveled. Also, don't raise the port or it will loose torque.

are these pm650's a strong running saw? I had too much Ice outside to run mine in wood today

I've only run one of my 610's in wood. It shows 175psi on my gauge and seems plenty strong for 60cc's.

 

[joeymt33]

They perform well with adequate torque when running a 20" bar. If the saw is 175psi or up to 190psi they will pull a 24" bar good. These saws seem to run very poorly after they drop below 140psi which is good for most saws.

Like most people say, they are slow, heavy, loud, and ugly. They good part about these saws is that they are plentiful, they make good torque, and they seem to last forever.

The 600 series saws had their drawbacks for sure but the line lasted from the 80's till Mac went bust. Very reliable, very good parts availability, easy to work on. If you want a saw to do alot of cutting with and you don't mind the weight it will take the abuse. I have seen these saws look like they have been run over and all kinds of things but one or two pulls and they will usually start. In my experience the oilers in these like 30w motor oil. I have tried several brand of chainsaw oil and end up going with the 30w. Also seafoam or something similar atleast once a month if you run it heavy.

this one sounds mean!

seafoam in the fuel or oiler?
