    Just acquired the old girl haven't got to mess with it much yet just compression tested at 165psi so I think it's worth messing with for a fun toy. Was a saw my old boss took on trade of a tool rental and I ended up giving him $50 and giving it to my brother this is easily ten years ago. My brother ran it a little on and off since then and just gave it to me it's pretty darn good shape and all original with a 24" bar. Anyone run or own one? IMG_2239.JPG IMG_2240.JPG

    I think these were a big brother to the venerable PM610. Should have a ton of torque and keep the wildlife at a fair distance.

    I think thistle would know more.

    I've had 3 PM610 pass thru. Used a little and sold. Slow chain speed but lots of torque. Pulls 20" bar with authority.
    But the saw is like holding your push mower by the deck and using the handle as a the bar.
    From what I've read, the PM650 is also 60cc but w/ decomp and a little higher compression than PM610.

    I've owned several of this series of the McCbricks through the years, although they get dogged on because of their looks, weight and vulnerable ignitions and oilers, out of all the ones I've owned I've never had an oiler or ignition unit go bad, just lucky I guess, I cut a lot of wood with my first of this series that I owned, the puke brown special edition timberbear, no complaints at all with that old saw, except for selling it, I currently own a monkey wards variation that I added the duel spikes and the hard to find downward exhaust deflector for the muffler.

    Yup 60cc ''semi-pro'' model with decomp button.Heavy for its power,loads of torque,damm near indestructible.My early 70's 54cc 10-10 Automatic weighs about 5 pounds less & will keep up with it & on a good day will out cut it.:dex:

    Factory specs claimed 30% more HP than standard 610 cause of more aggressive cylinder porting. Not as common as the 610,produced from 1978-85.

    The 610 from 1978-94 - first version with wraparound chain brake/hand guard from 1978-85,2nd version with more conventional chain brake 1985-94. I've had both,2nd version new from 1992-2000 & my current super clean 1st version bought off CL for $40 in July 2013.Nicest one I seen that wasn't New Old Stock in a box with original paperwork.

    Don't have one but may get one someday.

    Looks really familiar to the pm610 that was the family wood cutter until it was replaced by my 029 super.

    Our old 610 still runs good, my buddy fired it up the other day.

    Yes, those things will wake up all the critters.

    What do you mean by "slow chain speed"???

    My 610 used to have a 28" bar on it, and it'd just eat wood up. It now has a 24" bar for better balance, and is a pleasure to use. It's not meant for limbing, or climbing; but is an absolute monster on felled wood.

    Some motors are screamers, and some are torqiuer. It has to do with how the motor is designed, that's all.

    The Super 250 is bad azz....One of their factory hot rods very close to a full on racing kart engine.5.3 cube/87cc with enough power to pull 42" bar/skip chain all day in softwoods,36" if full chisel/hardwoods. Puts their regular 80cc 200/250/300 models in the dirt very quickly,no comparion in speed & torque.:dex: First version produced 1968-69ish,its basically same as the more common 1970-75 model,just slightly different air filter cover decals & a couple other minor differences.

    I have a few pics I can post later,if I remember...lol

    I've owned several 605/610's, never owned a 650. I know they are a little harder to find.

    Most of the 605/610's I've tinkered with had ignition issues due to the spark plug wire being in close proximity to the flywheel. The wire would wear through from the flywheel rubbing it and eventually ground out. Also they have weak, vacuum-operated oilers. Both issues were easy fixes. But I made a lot of moola using them back in the day, until I saved up and could afford my first Stihl......

    I still have two or three of them in my shed, they all run.

    The deflector attaches to the cylinder above the muffler; it is a bit hard to see in this photo of a PM5700 but it is there. If I recall it attaches with one screw.

    Mine looks just like the picture you have with the upper deflector that "protects" the decomp valve and the open muffler. The deflector I was looking for goes on that open muffler flange with two screws in order to blow the exhaust out through the clutch cover

    Haven't used that model, but I learned how use a chainsaw on a pm-605. Used it for years until recently when the top of the fuel tank cracked. It was also the only saw I ever used until recently, I couldn't believe how light all the other saws were in comparison!
