What's on your bench?

Late model 7-10 getting cleaned up to go in the display.

Here's a shop tip that nobody remembers or they weren't taught.

One of my biggest pet peeves is recoil ropes that pull out because of a slipped knot.

So after you melt the rope and smooth it out for ease of installation. You tie your knot and ship it. That's where the problem is. That slick and smooth end will ruin your day when you least want it to. What I do to eliminate that issue is re-melt the end after the knot is tied and flatten/bulge it out with the backside of a pliers or screwdriver. Makes it nearly impossible for the knot to slip out of place then.

I tore this John Deere / Echo trimmer apart to give it a good cleaning. Anyone know where to get a new air filter?

Next up is this very early 7-10. Low hours but very dirty and the crankshaft is chipped under the clutch.

How did that happen? Was there a keyed clutch on that, without the key?

I don’t know dick about them old macs but they are always interesting and tell a story. Seem to be tough as hell. Some folks are good and tearing things up though. If a guy can fuk up a ball bearing with a rubber mallet i suppose and old tough Mac didn’t have a chance unfortunately.

Yes, keyed clutch with RH nut. It had evidently been run loose as some point and cracked off a piece of the crankshaft that went 1/2 way around. Good news is the 70 cc saws share the same 1.375" stroke crankshaft with the 54, 57, and 60 cc saws so I have a lot of options including finding one without a keyway that has LH threads.

Thank you for sharing that information. I don’t like to pester people for knowledge but I always appreciate it when folks share!

Very nice 3 wheeler Richard. And a diesel to boot. Nice mowing machine.

 

[heimannm]

I did manage to get the 7-10 cleaned up and started putting it back together. I changed the crankshaft for one without the keyway and with a LH thread so I can use an unkeyed clutch with no trouble.

Checked out another MS170, this one was a no start. Determined it needs a fuel line, filter and carb. Fuel line is super stiff and cracked. Figured in a carb to cover my butt. Fuel filter just because.

Checked out a Dolmar PS6400 no start. Compression good, piston good, spark ok. Wouldn't go on a squirt of mix so I checked the plug, super wet but didn't smell like fuel, dumped the tank and found water in the tank. Cleaned/dried the plug and cycled some carb cleaner in the cylinder to dry the water up. Followed with some light oil. Figured a carb rebuild and fuel filter will make her live again. Gonna let the tank dry out for a few days.

Looked up parts and wrote estimates for both.
