not so pros

Came from a running ported 7900 tho.

Everything works off pressure on a carburetor. Forget what the top of the piston is doing, think of what the bottom is doing to the primary compression in the crankcase.

Are you thinking it has something to do with timing?

Dont know. I had the timing advanced. Returned to stock and it did the same thing

Yes, time to throw in the fire and watch for pretty flames. Lol

I get what you're saying. Tomorrow I'll bolt the 6421 cylinder back on and see how it runs. If it does, it's some combination of the cylinder, piston, or impulse

It's always an option

You increased the pressure/vacuum(pulse) signal to the carburetor by installing a BB kit, the carburetor therefore is no longer able to contain the inlet needle at low speed. At high RPM it can use enough fuel not to notice the difference.

Makes complete sense.

I'll throw it in the fire then

 

[Stump Shot]

Some BB kits go on without a hitch, while others are a PITA. Must depend on the proportion of things relative to each other or some such nonsense.

Got the little Poulan/Craftsman 2.0 running today. @Jon1212 Carburetor was very sensitive and hard to adjust and stay adjusted, when saw was turned on one side it would speed up, the other side it would die. It was oiling and I did manage to cut a couple pieces of wood, it did real good with that new Raisman chain. Pretty sure you know the diagnosis from what I've discovered.

Edit: Also it didn't run like a ported saw at all, whomever did the porting, must have had a real light touch.

Do you need me to look for some seals for it?

Very little remains, most of it melted.

No, just giving you the report is all, and busting your balls, as you and others have asked about it.
What would be the Poulan name for that saw? I'm thinking that route would be easier to go through than Sears.

2000 is what mine is called

I bet that will work. Surely looks the same.

And I think before the 2000 moniker it was XXV. They were also made in this flavor too.
Not my saw by the way.

How about this since we're showing them off...
