I've used nuts in the past, but there a pain

‘‘Tis why I done what I did sir!!

Kinda refreshing to see a real 440/460 being built. Easy to buy a new 462/572, this is the proper way to build the heard using select proven genetics.

I did the same with my hybrid, could’ve bought a new artic 462 for what I’ve got in it.

I like the idea that it's a nice clean part that looks like it belongs there.

Another reason I hated using washers

Back in business!!! Welcome back sir

I used nuts also, pretty sure I welded em to the muffler

Was my plan as well. The torch will be out for adding the deflector anyhow. About 2 minutes more work.

I know Scott does screw on deflectors, but also that he tig welds.

I’ve built around 10 of these so far and the spacers were around $10 Each. A cheap item, but the box of nuts costs $8 and will do another 50 saws.

They do make the muffler unusable on any other 1128 though.

Scott, see you PM’s

What is the rear handle element attached with?

What is the rear handle element attached with?

It just slides under the black trigger assembly cover.

 

[Jimmy in NC]

The MS440 I just did was clean but dang that is going to be a sharp saw Scott.

So no adhesive? I am putting together an 066 with a used element

Not that I saw on a 046 arctic

 

[huskyboy]

You have to route the wires a certain way on the sides. You’ll see. Kind of hard to explain without pictures.

How did intake duration end up? 158-160?

How did intake duration end up? 158-160?

Been puzzled by this Hybrid question myself.

Smaller case under bigger jug. Not that much different then adding a full circle crank to a 460.

Too much intake, just more blowback. Too little, not filling case enough. Perfect, full case and lots of primary/case compression.

Same size to larger intake tract as a 440.

Puzzling.

I try to look at what Stihl did with timing when they added a bigger jug to the same size case in the same model line. Gotta figure them Germans, with this being their full time job, had to know something.

I designed a nice muffler spacer a few years ago because farkin with washers was a beotch.
Scott......I ain’t charging you a fackin dime.
If I have one here, it yours

thanks bud

larger bore increases case volume
