Homelite Chainsaws

A 26 LCS question
I got a seal for the flywheel side that was leaking and installed it.
Then I pressure tested again and found a hole in the crankcase that leaked under pressure. It is on the edge close to the belt case.
Is this a case where it’s supposed to be open ? The parts saw I have has a casting mark but no hole
Thanks

Doing some thinking, but can you see the crank moving through that hole?
Because, I believe that should be the outer race of the main bearing visible.

Edit: I take that back. The bearing is the raised area to the left of that hole. Must be looking at the crank between the bearing and the seal.

Here's my 26. The only port I know of is for the tank pressure line. Maybe your case came off something else.

I thought I had gotten back to you on this, but I can't find my post, so I probably messed it up somehow.
Anyway my 26 does have that hole in the case, and it appears to go clear to the crankshaft. My saw turns over with compression, but it's missing some pieces, so I've never tried to start it. It looks, however, as if it was used with that hole open; there is no provision for plugging it.

Thanks Jay
The one I am fixing is like that.
If you are looking for parts let me know as I have a saw for parts which is like CB’s saw
I can’t remember by the serial numbers which is the newer saw.

You can see something which I assume is the crank but haven’t looked to see it moving.
I am pretty sure it’s all original to the saw as the case shows no sign of being worked on, but they are 50-60 years old

I will surely be needing some parts, thanks for the information. Now that I know of a potential source, maybe I can try to determine what is missing from mine. I know it needs a cylinder shroud and a muffler, it also needs some throttle linkage parts, but I'll need to locate an IPL to figure that out.

By the serial numbers that were on the saws, the one I am fixing is the older of the two.

That might indicate that the hole was problematic early on, and they addressed it right away. I t kind of begs the question as to why it was there to begin with. Homelite was in to other things at the time, maybe that was a multipurpose engine, and the hole served a purpose in a different application?

Hello all, hope this is the right place to ask this, but I had an old 700 D given to me about a year ago that I'm finally getting around to playing with. Waiting on a carb kit as the diaphragms were hard as rocks and it should be runner. I pulled off the "muffler" today to clean some carbon out of the exhaust ports and was surprised by what looks to be a rather high performance saw. Large dual exhaust ports, six transfer ports and a domed piston! Does anyone have any hands on experience with one of these? Are they a governed saw? Is there any easy modifications to increase it's performance? Any input is appreciated!
