I’d like to get my SP125, stihl 090, 090g, 797 super, homie 750, jonsered 111s together for some long bar fun.

That would make for fun indeed! I have an 090g with 66mm topend, but it seems slow. I really like the homelite 750, it has nos rings and feels solid, but I think it would like some timing advice! My 2100cd is a good runner, I did a base gasket delete and it has 185+ comp and is a b-word to pullover without a decomp, I haven’t ran it much in wood since the bgd, but it seems strong! Haven’t ran 50” on the homelite or 2100 but I think they will do fine. We should have a mini gtg, and have a huge long bar shootout, or go to the pnw one.

I don't think 090g's really show you anything until the bar is at least 72" or a couple of feet more. We've done some long bar stuff at the PNW gtg. Bob had an 80" log there for fun. I'm gonna try for a Mac 73 vs 7-29 shootout next year with 60" bars and 9/16 chipper chain.

I haven’t given my g much of a chance, I never have set up a chain for it and only have a 50” .404 setup. I have a 64” bar but it has 3/8 chain, it’s a hard nose bar so I could get different chain. That sounds like a fun test, I wish you had some videos of that!
I am going to test the wb with 3/8 9pin on the 50” bar, looking forward to the 750 and 2100cd test too, have the sp125c to compare to, but I already know how it dose

24 Needles is correct. Here's some torque specs I got from one of the guys over at rearviewkarts.com:


torque values
Coil/lamination Screws ------------55-60 inch pounds
Condenser screws ----------------30-35 inch pounds
Con rod - mc49 mc 91 -------------105-110 inch pounds *
Con rod - mc101 ---------------90-95 inch pounds *
*a master mc builder told me told that 101 rod bolts with 85-90 inch pounds and red loctite is bullet proof
and torquing to 110 results in cracked caps.i myself do 85-90 inch pounds
Crankcase End Cover Screws --------60-65 inch pounds
Crankcase Bottom screws -------- --95-100 inch pounds
Cylinder Head Screws -------- --55-60 inch pounds
Exhaust Header Screws -------- ----55-60 inch pounds
Fan Housing Screws ----------------55-60 inch pounds
Flywheel nut ----------------------300-360 inch pounds
Spark plug -----------------------216-264 inch pounds
Clutch Nut ------------------------ 260-300 inch pounds

Thanks for the info.
Do you use locktite on the rod bolts?I am hoping that i never have to take it apart again,but it sucks when they take themselves apart.

I use Loctite - I go to about 90-95 inch-pounds with red loctite. How is your connecting rod? Are the journals smooth?

I'm thinking 3/8 may be too little tooth, then again my SDC 101b did not like 8 tooth .404 but 7 is nice. 3/8 IS too little on a 090g for sure. And .404 seems to be too little on large 6 cube + Mac & Homie geardrives. That 125 should have considerably more torque than a 750. The 750 has more speed, but neither of the two I had could hold a candle to any 123cc Mac with a long bar period. The 111's I had both had a lot less speed than a 750 but the same amount of torque. I like a 111 way more than a 750 for longer bars as to me, the lower engine speed gives less operator fatigue. The 2100 Homie has the torque but handles like an old truck where the 125 feels like a muscle car. Still a 125 is possibly stronger and to me is much nicer to use as a work saw. They are sought after and have a mystique for a reason. I feel they are the best over 6 cube saw ever made with the conditional (very long bars) exception of an 090. Yes a 166 is more elegant, however to me, a 125 just feels better when it's time to get down and dirty.

Figured I would post this up here too.

That looks quite impressive!!

Thanks Frank, I did run the 2100cd and homelite 750 with the same bar/chain in the same wood.

I hope you ran them before the 101/125 lol. I’m betting they’d feel pretty slow comparatively.

I did play with this a little bit today...finally got some spark out of it...thank you @jacob j. needed a few
Parts, breaker box cover, and hold down brackets, flywheel nut. Had a NOS condenser, which I installed. Then cleaned up the points, and finally saw some blue lightning. Shot a little mix down the carb, and sounded great!! Can’t wait to get some fuel in the tank...and get the carb wet!!

 

[Al Smith]

Just for comparison both my 125's run .404 actually faster than 3/8" .One has an 8 tooth and one a 7 tooth in .404 .The Homelite in my avatar has an 8 tooth which is all Homelite offered on the six spline rim drives they used at the time the saw was made and it's rated for a 60" bar .The only reason I have a 7 on the 125 is so it can run the same 36" Stihl bar I use with adapters on the Homelite 2100 S because of a slight difference in the bar studs .An 8 is one tooth too many .I've been asked which is faster in the cut and I have no idea nor if either one is faster than a Stihl 084 I have .I'll just say they all have enough .It isn't about speed any way on a long bar ,can it pull it buried and still cut the mustard without being babied --yes,yes and yes .

Were you busy yesterday getting people's power back on after the big storm? Lane Electric had several crews up here - parts of Lincoln county
were without power for about two days. Mine was off for about three hours or so in the worst part of the storm.

 

[Bigmac]

That is a minty 125! And a nice bar as well! Always like the black and yellow bars, you don’t see them very often though

Nah...didn’t get any emergency service calls yesterday. Was kind of surprised.

Got really
Lucky on this saw a year or so ago. Came with bar. Glad to finally have spark worked out. Checked compression...topped out at 180!!

That’s awesome! 180 psi is about the best i have heard! My 125c had either 170-175 psi, and am happy with it! That’s should be quite strong, you have an sdc20 or fixed jet?

It has a Tillotson hs124 on it.
