Andy is an odd duck for sure.

Sorry brother Deets. Not a #70 jet size.....a #70 micro bit size.

Makes sense now

What advantages do ceramic bearings give over traditional?

About 70% less rolling resistance.

I did some 1128 carb testing today, and all I can say is that the results are not conclusive regarding what carb is best.

I think it all just depends on what your saw likes.

No time to post vids, as I have to go away for the WE, and have to pack, but here is a summary of the results (testing done in 15+1/2" Pig Nut Hickory (tough wood).

Stated with my standard, the old 044 w/orig ZAMA C3M (Hong Kong) carb. Both cut times were in the low 10 second range (w/AM filter).

Put the HD-11 carb on, and cut times increased to mid 10/low 11 seconds.

Then broke out the Dr Al Ported 460 w/HD-50 and ran the best times of the day, a high 8 and mid 9 second runs (w/real HD-2 filter).

Put the HD-50 on the 044 hoping for great stuff, but times dropped, two cuts in the low 13s.

Now put the HD-11 on the 460 and both times were low 11s.

I now tried both the 044 and my CFB Hybrid with both AM filters and real HD-2s, but the 044 vid will not play, so I just have the Hybrid vids. It liked the real HD-2 filter better. The first two times w/AM filter were both in the high 11s, and with the HD-2 they both were in the low 11s, dropping over 1/2 second.

Both the 044 and Hybrid had AM air filters to start with, but the 460 had a real HD-2.

SUMMARY:

044 - Likes the ZAMA carb best, the HD-11 is a close second, and it absolutely hated the HD-50.

Ported MS460 - Screamed with the HD-50, not so impressive with the HD-11.

Hybid - I need to do more testing with this saw. It liked the real HD-2 filter better than the AM filter. Both the 044 and MS460 turned faster times with their best carbs, but putting it in a different light - The 460 was not any faster with the HD-11 carb, and the 044 was much slower with the HD-50 carb, which is what is on the hybrid!

In conclusion, don't ask me what carb is best, I can't tell you! TEST, TEST, TEST!!!

Hmmm. Interesting test results Mike.
Thanks for taking your time to do the testing.

I knew I should've sent my dam 044

 

[MustangMike]

Mine is not ported.

 

[maulhead]

Mine is not ported.

Thought you had a ported 044? What ya do sell it?

 

[RI Chevy]

I bet the carbs will give completely different results with a ported 044.
If I remember correctly, Mike did gasket delete, timing advance and DP muffler mod to his 044. Everything but a port job.
I think he needs to buy Mike's ported 044 jug. Lol

The cylinder I've got in the trading post is for a 12mm saw. Iirc mustangs 044 is a 10mm.
My cylinder won't work on his saw

how do you remember that ?

 

[MustangMike]

I think my 044 was a very good jug right from the factory, and Jeff described my mods.

Did the same mods to my MS440, and I really like that saw also. The 044 is a bit faster, but I'm not sure it has more torque! Was noodling Oak with the 440 today, and it did really well!

Mike, did you retune after changing carbs?

 

[MustangMike]

Did not, but they all idled well, responded well, 4 stroked out of the cut and cleaned up in the cut, so they were close enough.

Usually about one turn out on the low and 1+1/8 out on the Hi works well for this series after mods.

That said, everyone should, and should know how, to check by ear.

Forgot that one small detail Mike. Lol
An important one too.

Here is my unported MS440 noodling Red Oak. It really behaves like a larger saw!

Looks good Mike. Saw sounds real healthy

What's the rpms at WOT?

 

[MustangMike]

Not a clue, and if I tuned them I would go more by ear than RPMs anyway.
