Re Creating a Classic 046

[JonCraig]

I heard there’s a coil on the early 046’s that runs better if that’s true. Not sure the #. I think mine has 1309 coil or something along those lines.

1309 Coil is the more desireable one. @jacob j. told me that they have a more aggressive timing curve. Here's a pic of mine that came on an early 046, D-jug (with "good" port timing numbers):

Awesome, I advanced key .020 and she already kicks if your pulling it half assed

Do we know how much more advance it provides? If we did, we could make it up with the key cut.

How is that new saw running Mason?

How is that new saw running Mason?

I gave it .025 off piston skirt for more intake timing, ex port widened, cleaned up piston/windows, ground lip out of intake/lower transfers/casting boogers, gasket delete, .020 timing advance, opened up the restrictive air box(via a big hole in bottom of cover) and ground the carb butterfly screws. Its strong, holding 10.8-11k self feeding 24” bar 8 pin in maple tuned to 13.3k. I had it around 14.1 and still 4 strokes strong.

How many % of the bore is the ex port stock on the ones you have mike?

Air filter cover mod

Mason whoch saw is the new one Mike is talking about? You seem to have vastly expanded your saw arsenal in the lsst couple years. What saws do you own now? I know you have atleast 1 394 a 395? 372 562? 550 and what else. Hell i cant keep track especially when you are running borrowed coworkers/bosses saws.

Talkin about the 046. The ones I own (bought with my own funds), mastermind 395, awol 562, 046, 2253 and a 385 with a am 390 cylinder. My father’s saws that I work on for him sharpen chains ect... 394, 125 mac, 350 husky and a Mac 10/10. The ones I don’t own that are work borrowed 461/661. Hope I’m not forgetting anything. Lol

You need a max flo filter now. Lol. For the 460

Yes I do, that would probably be bigger gain than anything else I’ve done to it

Or save that sucker for an 064

I appreciate the Doc's offer, and maybe down the road I will take him up on that. However, my "self imposed" rules of my little game here was to see what the average guy could do with a Hemi Jug and a D jug, respectively, w/o any machining. In other words, just do at home stuff that most of us can do.

I was planning on using that OEM piston, and I still may, but I already have some Meteor's on order which should arrive long before the tank handles, so I will check squish with one of them.

I knew from measuring the jugs the squish band on each would be different. However, I used the Hemi jug with the tighter combustion chamber, so .018 may be a bit much. However, the exhaust ports are higher on the Hemi jugs, so that may balance things out. If the Hemi is tough to pull over, I will just add a thin base gasket.

Hey, if the D jugs ran great with a base gasket (and they did), it should be much better now! We will see.

Basically, I want to see what these things run like with a base gasket delete, timing advance, and muffler mods. That combo worked very well for both my 044 and my 440, so I want to replicate it with these two saws. Will see what happens.

Wonder which piston, OEM or Meteor, would give better performance after ported? I saw the Meteor weighed more.

Oem is lighter I’d guess. Meteor has wider skirts. But what you can’t make up in area I would guess you can make up with time? I read treemonkey saying that somewhere.

(I’m going off memory, so forgive me...)

I think it’s a different advance curve; not just a static amount. I think it had something to do with the poly flywheel, but @jacob j. would be able to speak far better to that than me.

I’ve been meaning to try shaving the key on mine to see what the results are, but haven’t gotten around to it yet.

I don't know, but they look decent. I know there is room for improvement, but I don't feel skilled enough to take advantage of it at this point. However, I did put some crude bridge ports in a hybrid cylinder today, they are cheap enough for me to play with, and easier to cut than OEM.

 

[MustangMike]

Made some more progress on the 046 D today, really just waiting for a tank holder to come. Hopefully, soon.

Put the clip on the crank, installed the oiler, the clutch, chain brake (w/my brand new covers), the flywheel with key cut .020, and the orig back of the muff. Has a new (to this saw) cover because the original was missing, but the back half has the large 5/8" hole and no baffle. I hammered the cover out (it was bent a bit), and drilled two 5/16 (instead of the 2 1/4" I normally do for customers). Gosh, they look huge, it should flow well.

Still need to pick a coil from my junk bin collection, and I have a AM recoil with OEM elastostart rope + handle.

Looking forward to running this one!

Did you notice in pic #2 that I reconstructed the boss in front of the oil cap with PL Premium? Not bad huh?

Also, I pulled a rubber bumper from the left rear of a 460 case only to realize the 046 does not have one … no hole to install it, and does not look like enough material to drill the hole. So, I checked what rubber I have that is the right thickness, and an old style fan belt will get cut, and a little piece will be glued to the case in the appropriate place with PL Premium. That should help to reduce vibrations and preserve the tank holder.

 

[MustangMike]

Well, right after I got my 440 Big Bore #3 running today (the first saw I fully ported myself), my 3 046/460 tank holders arrive.

So I figure get the D jug saw running and compare the two, how long can it take? As I start installing the long screw in the top AV mount, it breaks off in the case. I remove the case, get my EZ outs and drills, ended up drilling all the way through the screw before the EZ out would remove it. Then, re install the tank holder, hook up the coil, all the screws + caps, etc, go it install the carb flange and the bolts are not long enough!!!! It was then that I realized they send me 2 MS 440 tank holders and one MS 460 tank holder. Remove the 440 tank holder, install the 460 tank holder, get the saw running … and the wife has a Honey Do List.

Says something about that I can't just play with saws all day long!!! Imagine the nerve of that woman!!!!

Bottom line, I got two saws running today, they both sounded good, and I'm looking forward to testing them (hopefully tomorrow). However, it has been hot as an over around here the last couple of days.

Gotta make some video of the 046 and hybrids cutting
