Homelite Chainsaws

Homelite 750 Intake boot replacement. This one ain't soo pretty......

Replaced the intake boot and impulse hose on a friend's FILTHY old logging veteran Homelite 750 and rebuilt the carb. Traded me my McCulloch SP-81 for the work. He paid for the parts. Spent more time cleaning the saw than anything else. Took out a coffee can full of sawdust/chips/dirt/pitch/dog hair. Lots of dog hair. Mixed with pitch, that stuff was like fiberglass mat and resin....

Here it is partially torn down. This is AFTER the first attempts at spraying it down with my kerosene/ATF mix (that usually wipes saw grime right out) and letting it soak.

There's the largest recovered piece of the old intake boot next to the new one. Old boot turned to chewing gum.......yet the saw still ran.

New boot and impulse hose in place on cleaned engine. Put that aside and rebuilt the gummed up Walbro WB.

The old warhorse back together. Took lots of soaking and scrubbing in diesel. The diesel is now jet black. I scraped a coffee can full of scum off of the bottom of my cleaning tub after I drained it...

Unfortunately.........I'm not done with it yet. Before I started the project, I noticed that the throttle was sticky. Thought it was just gummed up (not a hard assumption to make based on how the saw looked). Got it all back together.............and found the real problem. Homelite cheaped out and made the throttle trigger out of plastic. The hole in the trigger where the throttle rod fits in is worn out. When you pull the trigger, the rod slides out of the hole and jams against the inside of the handle. DAMMIT. I'd finished getting the saw together at about 10PM last night (so firing it up wouldn't have been the best idea..............but I was gonna do it). The stupid trigger has put it on hold. Now I've gotta find an NOS trigger or a good used one. Anybody here have one they can spare???

The bottom handlebar bolt hole on the clutch side (full wrap part of the handlebar) is stripped, as is one of the bottom handlebar brace holes. Should be able to helicoil those. Main concern is that damn trigger. Can't rut it at all until that's squared. It's not even easy to REMOVE the damn trigger. I drove out the pivot pin, but couldn't get the trigger to come out. Think I have to remove the comp release lever pivot pin, spring, and parts to allow the trigger to move up enough to turn and clear the slot. Getting those back in isn't going to be fun. The handle/carb box is also cracked just in front of the comp release lever assembly. May just replace the whole carb box/handle assembly if I can find a good one. Anybody got a spare assembly? I know...........good luck with that.....

Good job. Nice early six clutch shoe model.

Super 2

Took it back to dad today and tried it out. After a while it would accelerate with nose pointed down....whats that about?

Also sometimes i would get a screeching sound while blade was running. Im afraid to ask what that is, but i need to know. Any ideas?

The first part sounds like crank seals. The second part sounds like the auto oiler isn't working and the chain's running dry.

Awesome Aaron, and much appreciated! Yep they never used to clean those saws. Road in the pickup everywhere, with the dogs, pigs bar oil. Gas etc down all the logging roads. John does alot better know, as he gets jeaulous looking at my saws:msp_w00t:

 

[BroncoRN]

How hard are crank seals? Is there a clutch bearing?

Not too bad once you get the engine out of the saw cases. There is a little roller bearing in the clutch. It only gets used when the saw is idling and the chain isn't moving. When the clutch is engaged (and the chain is moving) that bearing isn't getting use.

I can certainly believe it Norm. There was pitch and dog hair EVERYWHERE. Even the choke button was coated (on all sides) with pitch. Thought I saw some hog blood on the saw too.

Some of the pitch had started etching the magnesium (must be acidic). Thankfuly it didn't pit the metal. One of the generous Homelite nuts here is sending me a good used rear handle/carb box assembly with good trigger parts. I replaced the duckbill valves in the fuel and oil caps while I was at it, as the originals had turned to goo (as the often do). That old beast will be roaring again soon!

Wow, Homelite 750s must be in season, just bought another one. Put the first one on the marketplace, I'll be uploading pics of the other one soon.

Your friend really shouldn't be cutting up dogs with a 750, lol!!!!

Pitch is acidic for sure.

Nice work. Next should be the McWelder.

I'd thought the same thing. More like the saws were covered in pitch, oil, and such.............and rode in the back of the truck with the dogs (and the dead hogs fresh from the hunt). From what I understand, the saws shared the same porch with the dogs as well. My SP-81 came from the same fellow ('twas a trade for the work on the 750). It was also full of and coverd by dog hair, but not as bad as this 750. Of course I haven't completely torn that saw down yet. I have spied more hair and gunk between the tank and the engine on that saw. Under the flywheel cover and clutch cover was certainly a ton of it...

Nice work. Next should be the McWelder.

Thanks JP. I can turn my attention to my saw projects once the other fellow's saws are finally done. Replacing the oil tank and crankcase stuffer on RandyMac's 790 next weekend. Also pulling some XL-12/SXL parts for a couple members here as well. Then it's on to the 740W1 'McWelder' (McCulloch 740 with a 103cc W1 welder engine swapped in by someone long ago), my XP1020 Homelite, my XP1130G, a couple Super E-Z Autos, a Craftsman 2.1A/Poulan 25DA, my Homelite 900D, my Dayton/Poulan 245SA, then...............:msp_w00t:

Dodged a bullet there Aaron.

On Remingtons, Ropers and Lombards I'm seeing the same trigger used.


Freakin' smilies never work when you want them to.......................................

You've got that right Carl. He contacted me not long after my post too. An unexpected pick-me-up to be sure. I've found NOS triggers on feebay, but no carb boxes. Could have gotten it going with the trigger (and much swearing when swapping it out), but the handle/carb box would have been a failure waiting to happen. Much easier to swap it out as a unit as well.

id?

Any ideas on what this is Wiz 80??

 

[hoss]

I'm thinkin Wiz66, but it might be an 80.

Looks to me like it sez "80" on the AF cover. SW80 is my guess.........unless the cover was swapped. Then I'd say it could also be a SW77.

To assuage the pain of missing that 750 a while back, I let this little feller follow me home tonight.

It didn't really help. Maybe I should've gotten 3 of them? :hmm3grin2orange:

 

[homelitejim]

The Super EZ is the best small saw Homelite made, not to many 40cc saws with a decomp and ability to run 3/8's over a 20 inch bar and oil it with authority.

I've always liked the looks of them and it is really clean. Unfortunately, he left gas in it 4 years ago so I'm sure it will need new fuel lines.

And as an added bonus, I finally got a case! :msp_thumbup:

only one line in the ones I have done, not sure if I remember correctly but uses about a foot or less of line from the bottom of the tank to the carb, out a small hole on the flywheel side and into the carb box.
