should I post some more pics? 1 without the boot or inside of cylinder.
The guy I got it from just told me he is pretty sure 1 is off a 266. could I pull my cylinder off and just try it to see if it works. My cylinder has different casting numbers then both of these

I assume from the pictures that all you got was the cylinder, correct? Take your calipers and measure the diameter of the bore on #1 if it is a 266 it will be 50mm as Magnus stated.

Should be different diameter on them 50mm on 266, 48mm on 630.

What are the casting numbers of the cylinder on the saw now?

What makes you think your cylinder needs to be replaced?

If you have both the cylinder and piston, and it is 50mm your home free, otherwise you will have to pull your jug to be sure

I just have the cylinders, My cylinder possibly can be fixed. But if 1 of them cylinders will work on my saw it would be easier just to swap cylinders.

Jim is that what the little mark is to the far right of the '8'? Just ahead of the rear flange bolt hole.

Well that would be cool but again why do you think your cylinder needs to be replaced? Pistons usually suffer the most damage, so if the piston is damaged then it will cause damage to the cylinder which can sometimes be cleaned up. All of this is moot if the damage is external to the bore, like broken exhaust flange or cylinder fins.

The previous owner stripped the muffler stud out and drilled it out very big and filled it with jb weld and drilled the muffler so they could put bigger studs in. It all come loose when I got it. so i cleaned the holes up and put more jb weld back in it then drilled it and tapped new threads but its all loose again,
I'd aluminum weld over it and drill and tap new threads if I had the equipment.
 
Id take suggestions on how to fix it. I just want it fixed right not the half ass job thats it has now lol
I think my easiest quickest fix would be to swap cylinders if I knew that 1 of them was a 266

Welding up the holes and retooling is the best way to fix the problem with the current cylinder.

Your theory of replacing is the cheapest way to go since you have no $ in a replacement. I think you can be fairly certain that #1 is a 266. Give it a shot, you have nothing to lose since you would have to remove the current jug to have it repaired anyway.

I have a 61 piston and ring and just to see I put it in cylinder #2 and it fit. It was to small for cylinder #1. So now im going to just go ahead and try it, if it works then great.
If it doesnt I'm gonna have to find some to weld it the holes so I can get it re threaded.

The 266 had a 50mm bore, the Jonsered 630 is 48mm as is the Husqvarna 61. IIRC the Husqvarna 61 and the Jonsered 630 are basically the same saw.

Good luck with the cylinder replacement. IIRC the torque specs state 8-9NM for the jug, and use a NEW base gasket! As well as a good amount of 2-stroke oil in the bore, you do not want to start the saw with the cylinder dry!
