Hybrid Build

[Definitive Dave]

So, since we are derailed anyway:

Yesterday I visited a HS friend I had not seen in over 30 years. He collects "stuff". Has an assortment of bull dozers & excavators, many of them very old. One of his bull dozers has a block & tackle to lift that blade, and has been sold to a museum in CT (It is WWII era).

He also has hundreds of riding and non riding lawn mowers, and a few chainsaws, including several 2 man saws. Likely the most unusual one I saw was a 2 man saw that had two handles on the operators side (one for each hand), and ran on a 2 cylinder Mercury marine motor. I believe he said it was a Dolmar.

Real interesting stuff. I know he sells some of the large equipment, but when I asked him about selling anything else he told me "sell" is a four letter word, he much prefers "buy"!!!

He is very good friends with my other friend Harold, and I will have to see if I can get them both to come to a GTG in the future.

sounds like a few DISTONs the grumpy old man has in his shop

Not sure if it's necessary or not.
But case castings vary slightly from one to the next. The offset seems quite prevalent here so I'm gonna grind it to be safe. It won't hurt.
I won't be using 6mm jug bolts. Don't see the need.
As far as an 064 piston....that's a good idea but I don't have any machine tools here at the house to adjust squish or turn the base if needed so I'd rather just build it the way I know.
I'm not porting this saw. It'll be a stock build. If Dave wants me to send it to a builder when I'm done I'd be happy to.

Randy (no the other Randy) said he would give it the porting magic when its ready, I am completely up for a piston swap if it makes it mo' betta' !!!

I'm not liking the looks of the Farmertec flywheel









I had to clean the ID threads so in the future this thing would be able to be pulled using the standard STIHL FW puller

I have OEM flywheels if you want one, say the word, I can send it with the OEM Gasket set.
If Amazon has the caliper doohickey ya need send me a link and I will get it on the way to you as well.

If you have an OEM flywheel I would prefer to use it. This one looks like it might disintegrate. Just make sure it's an 044/440 flywheel. The earlier wheels were a bit heavier which I also prefer.
The caliper doohickey is not required buddy.

Here is a visual difference between the old (1) and new (2) flywheels

I'd like to take a quick moment and give a great big THANK YOU to a very generous AS member @Derrick Sawyer for this beautiful toy.....or I mean saw. Bring on the hybrids fellas I'm listening now more then ever. I plan to run this saw for a little while before doing any mods but down the road I can definitely see a hybrid in my future

IMO, tearing a perfectly good running 044/440 down to turn it into a hybrid is just silly.

I hear what your saying and I agree. That's why I'm gonna put her through her paces for awhile before I do anything to her. I'm curious to see how it does up against my 038 mag

Who is this DDave you speak of? Is he new? Should he be trusted? Is he knowledge adjacent?

Thanks Ted, you are a true and dear friend.

How much did u take off?

 

[Adirondackstihl]

How much did u take off?

I bet 0.040-0.060 would cut the mustard

I like a strong 440 as well as the hybrids or a 460 which Ive ported and putting back together now
