2100 CD Build

Here is a close up of the piston that came with my saw:

Exhaust Side: Both locator pins here.


Intake side: With some JB Weld and Scotchbrite I should be able to buff out the cracks.


Top view: Previous owner did me a solid and marked the top of the piston for me.

Exhaust & transfers done.

 

[Sloughfoot]

Did you widen or raise the exhaust?

Both. I had to raise the exhaust a lot.

I'm quite befuddled with mine .I did a complete rebuild on the carb including the passages below the welch plugs .I've never had to do that before on any carb .It will fire on a squirt of fuel but die out so it's a fuel delivery problem .It might be a bad seal .Which would explain it .if so .Back to the shed again .

Did you check to make sure , ur diaphragms and gaskets are in correct order , just saying ,

It's probably an intake gasket blocking the impulse channel.

I hate it when gaskets shift when putting things back together.

I left a bit of rag I had been using as a block off in the intake after reassembling an 044 once. A little embarrassing when I finally figured it out.

Good thing you aren't a surgeon

 

[JIMG]

True. For very many reasons....

I don't think the gasket shifted .I have no idea why this thing worked good about this time last summer .However prior to "sawfest " it refused to start .I wanted to run it in the 100 cc class ..As it worked out on a fresh rebuild of the Partner P-100's I used one but again it was only at 140 PSI and didn't do well .That saw has slowly improved in the last year and if the 2100 won't work I'll use it again .The other Husky,281 decided it didn't want to run but I've got the modified 038 Stihl Mag that will out gun it anyway in the 82 cc class . .For reasons unknown I'm beginning to believe Husqvarna is mad at me .

Impulse was my first thought. You ever seen the impulse blocked in the case or carb body?

I soaked mine in Berryman's overnight and it got better but nowhere near fixed. It's getting an ultrasonic bath next. If that doesn't work it's getting a bullet.

One of the dumbest things I've done in the carburetor category was install a diaphram and gasket on the metering side of the carb, then bolt on the plate that also had a gasket and diaphram on it. Yes, two of each. It actually ran, sort of.

 

[Al Smith]

Oh I belly ache about this thing but it's like 40 years old .Sat on a barn floor for maybe 15 years on some island off Washington state .Those are probabley the original seals .It's not that big of a deal to change the seals nor is it costly . I'll get it one way or another,I always do .It's just usually you can tell if a seal is going faulty by the way it runs .I had no warning on this one .However some years ago I had a blow out on a Stihl .Stopped in heart beat that time .

Alright, port work is done, so one last look before the jug goes back on with some Dirko.

That's pretty, nice job!!

Thanks! I think it will run halfway decent.

Only halfway, Lol
