044 12mm case and too many hats

[Lightning Performance]

I feel pics are not needed at this time. Most anyone who might follows this thread knows what they all look like.

My case is a 12mm so I should be good with any bore size. The jug is straight fin and good. The piston is toast. I also have a 460 BB china jug given to me. The jug is OK and should clean up. It had a flat exhaust roof that grabbed the ring which broke the top of the piston off. I'm going to hack the case to accept all the pistons. The 460 BB may not work well.
And these nice jugs are: tight 38 DD lol you wish...

044 12mm straight fin OEM
440 12mm straight fin OEM
046 non D with decomp OEM
046 non D without decomp OEM
460 decomp OEM
460 BB China "NO PISTON" so?... need a good candidate!

046 OEM still together original saw not yet checked out
A 460 HyWay NE jug would be nice WhereTF are they?????????????? Still waiting :-( ... ... ...

Another 046 will be used for comparison shopping so to speak. Bone stock 046 to have a base line.

I can time them all and get the cylinder ID specs. This won't mean *s-word to me cause they are getting hacked-up if needed. Might drop a 50mm on the 46 just to see how it responds.

1. Is anyone interested in the combustion chamber sizes? Case cc's? Just asking...

2. Can a 460BB on a 44 case be a good runner with the piston size and weight?. I mean the vibs. We shall see.
Has anyone built a 44 case with a 54mm bore on top?

As far as carbs, muffs, ign timing, air filters and such they will all be set as close to one another as possible. And yes, the timing light will get dusted off for this and the tac will not be used. Always tune by ear here, hu? say what? Oh, OK. Two muffler cans to match the different exit ports will be in house to use. Several covers will vary in exit port size.
I have the 12mm pin pistons Stihl offers for these jugs plus AM Meteors and others.
It took me four years to find a good rebuild-able 44 case and crank for the reasonable price of a Benny. This is me be all end all 4series build. It will take some time.

Tips, tricks, twists and that 54mm piston reference. Speak up all you 44-46 gurus! And so it begins.

I started getting pics together but need an easy way to post them up here. Want to setting up an on line space to store them. Have a mystery jug on the 044 I just acquired for the 12mm case. It has the number 22 stamped on the side of the base. No other markings at at. It appears to be very well made and has nice clean ports.

None of them are KS type. Some are marked Stihl and some are marked Stihl and Mahle. None are Meteor. One maybe a China jug. Should have time later tonight to figure all this out and post pics.

IMO, if you run a stock 044/440 jug with HD-2 filter, dp muff cover, timing advance (20/1000) and base gasket delete, it will meet or beat anything else you can do. Usually, the squish will be very close to 20/1000. I bet it will also out run the stock 046.

use photobucket to store yr pics and copy and paste their links to here. thats how i do 99% of mine.

Great stuff

Guys don't love the 044/6 hybrid that much it seems. Case volume is often blamed. Adding a 54mm may make things worse, but I like how you think.

I'm wondering if a 54mm husky piston might not be the answer for you.

I must be the odd ball cus I really like the hybrids Doc. 70cc is the minimum I like for firewood and mine wear a 20".

Granted they might not run a 25+ as well but thats what bigger saws are for.

I plan on building one as well. I guess I worded that wrong, I should have said I'm surprised that everyone doesn't want one. They seem like the best of both worlds.

Looking forward to the results!

Now back to this. Just spent 5.5 hrs to go 100 miles, don't ask. The wife said to use my gmail but i need apps to run it. does the bucket use apps or email them in or text would be great.

I think the 54mm sucks to cut the case but it is what it is. I do not trust that junk 54 BB piston. I still need one to cut the cases while they are split. Mine has good skirts but they are short! It's broke on the top. Ate a ring in the flat exhaust. A taller piston will allow me to stack the jug up and cut the skirts off. In theory that should give me less case volume and that is the main goal here. Less is more. I want velocity not volume so maybe it will run like that JMS 064. One can only hope.

I'd pass on putting the 54mm jug on an 044/440 case. Volume is the main hindrance, but the BB jugs suffer from quality issues as well. I started building the 044/046 440/460 hybrids in 2002 and had the best luck with OEM jugs. That being said, a modded hybrid 044/046 440/460 still will not keep up with a properly modded 046/460 due to the mixing volume. The hybrid will win with a short bar in small wood but loses in larger wood with a long bar.

Still haveing trouble with my pics. This weekend will give me some time for that. This saw(s) is being built just to stir the pot some. It will get long and short bar tests.

Patience you banana eatin grasshoppers.
This aint Mcy D's drive thru!

54mm with broken piston. The jug is OK.

The mystery jug? I'm all ears...

 

[Lightning Performance]

Some more pics.

Top pic is the mystery jug.

Notice the 440's pulse port with no nipple in upper pic. These things, 044/440 have some very different intakes and other odd cast-in differences.

That mystery jug with the "23" stamped on it was on this running saw. Rings were welded in the lands. The skirt looks like it had a grinder run up and down it. Have no way of knowing how well it ran because the bearings, as you can see in the pics, were wasted! The seal was so far torn out I'm surprised the saw even ran. I found the case seal spring when I removed the oil pump lol.

I have more jugs. Need to dig them out soon. They most likely are 460 or 046 Stihl or versions there of. No KS or Gil stuff in the mix, yet.

Hey John I will get some pics of that Shinny this weekend.

This should be the inside of the mystery jug "23"
