Sounds good!

Looks like there's quite a bit of ignition timing adjustment due to the slotted screw holes... Where to set it?
Final port timing numbers are 98.5, 120 and 75.

Guess it would help if I post the photo.

Crank it ccw and hope I don't break the crank? Lol

I would crank it all the way counter clockwise. It is usually fine on dolmar 143s

Well it runs....like crap

Ran good with no issues as 285.....
Acts kinda like an air leak....but it idles fine...has a weird mid range stutter that can't quite be tuned out....will rev out to 12,500 then acts like a limited coil... Saw a backfire on the intake side..
The rattle ball governor has been plugged.
Gaskets look good. Coil is advanced all the way. Maybe too much? Idk. Guess I'll pressure/ vac test the case when I have time.

On the 2100 there is a brace that holds up the carb and mounts to the case, I would imagine that this is due to how the carb is mounted and the weight of the air filter that (without the brace) could push down on the intake mount causing air to leak in.

Is that a 045 ignition???

It will be good to find out, it doesn't look like what I have on my saw!

It is a 285CD Bosch setup

Good evening everyone I am in dire need of a ignition coil for my 1980’s 285CD HUSQVARNA chainsaw. I have looked high and dry and there was a guy selling one brand new a year or so ago just curious if anyone still knows where I can get one. My person email is Hitekrednek78@hotmail.com. I am willing to pay too dollar as this is my old girl but runs like no other saw I have. Thank you very much everyone.

Hey I have had good luck with the Bosch ignition using a transistor chip to replace the trigger. This is what I do on my dolmar ones

Thanks! I'll have find or make a carb brace. Don't recall ever seeing one on the carb....Though it was likely removed previous to my ownership.

Its a pretty simple piece, at an angle with a bend at the carb, two screw holes (green arrow = brace, red boxes are the screws holding them in).

Picked up a 2101xp over the weekend. Looks tidy enough, but unfortunately some scoring and will need a new piston, will do the seals and pressure/Vax test while I'm at it.

 

[Chainmale]

Looking at exhaust roof and piston edge, it looks like he had used a screw driver in the port to take the clutch off at some point.

 

[David Young]

that should clean up easy enough. I would really scrutinize the edge of the port. I would probably remove that area that was dented and a little above it.

Look how square that intake was. super cool.

I think I could slightly shape and re-chamfer the exhaust roof to suit. There's a couple little bits of transfer that can be removed. Don't think I'll get the gouging out completely but can already hardly feel them by finger, and they haven't broken through the plating

 

[Squareground3691]

Easy way to remove a 2100 Flywheel, take pressure off saw and onto Flywheel, these things can be a real problem after a few decades of being on and ruined if not done properly to flywheel or crank ,

My 2100 has worse marks and gouging and runs without issue. I did what I could with some scotchbrite to knock down anything that would be an issue.

That's good to hear. In those pictures I had already honed it a bit with sandpaper on a dowel with the drill. There's still a couple of bits of transfer to remove.
