I just thought about this lol, I tore it down and added some extra oil around the piston Friday night. Then started it with HP2, that excess assembly may explain the smoke lol the was less Smokey as the day went on Saturday.
Quick question with anyone that owns a 7900 what are your settings on your carb? I had to lean the saw out a hair and it was 4 stroking light under a moderate load. H was set 1 turn out.

It can be tricky with the limited coil, you may be hearing the limiter under light load. With the heat we've had lately it's not surprising if it's actually running a bit rich.
I have to rebuild the carb on mine maybe this week. I'll try to remember to take note of the settings and report back
And that's no lie. I purchased mine blown up. Rebuilt it from the ground up and ported it while I was at it. First cut was on a 10" green elm blow down. Had to take a few swipes off the rakers to get it to 4 cycle in the cut lol. My only limited coil....not a fan
Make sure the welch plug is sealed properly, if not replace the carb with a Walbro HD 12, same carb the old 372 uses.
Takes some time to get use to tuning. The issue is some saws will run fine set just under the limiter, the 7900 will be dog rich, they want to rev.

After all these posts and after all this time, 50:1 is clearly a conspiracy. Look what I find on my doorstep from a log builder who uses 50:1 I can fix them but not if he wont use at least 40:1. 50:1 is a glorified home owners mix.

Well at least he has good taste in beer.

Ya, it was nice he left the beer, but alas, it was shaken up almost as much as the saws were, so I guessed I had just missed Pete, cause Im just about ready to read him the riot act about mix. I'm gonna give him my 385 @ 40:1, that should smarten him up! Lol
If some is good, more is better.

send him here, make him read it all. lol
Shouldn't you take a look at 'em before blaming 50:1??
Maybe he, or an employee, strait gassed 'em... or...
Just sayin'.

They are easy to find here in Norway.
A family to me working in a Husqvarna shop, somehow they also sell Mobil oil, got it for 11,70$

That is always a possibility, but in this case not likely. He makes lots of long cuts and usually has bottom end problems. I gave him my 385 today to use and a jug of 32:1.
The husky looks like it has got a couple of million on the clock, it's probably been gone for a while & he was just waiting till another went, because you really can't give half a beer for fixing one saw, LOL

Yes your right, the 2100 had seen better days, but he got six months and two houses out of it so it doesnt owe anybody anything. I found it in the dump with a striped spark plug hole.
The 460 was scored on the exhaust and the 2100 was scored on the intake side.
The 460 is up and running thanks to the J&P that Cut4Fun so kindly sent me.
In defense of 50:1, the cranks were not dry on either saw.

BTW, could those two pistons be buffed out?
Just asking.

Well, where are they when you need them? Lol
Im really impressed with the 460 in how fast it starts and runs. I only did a gasket delete and stock muffler with the larger port. Stihl, in alot of ways is the better saw.
I traded the 460 for an 090g. Did I come out on the fuzzy end of the lollipop? Lol.
