Fun with a saw

[I Know Something]

Ok, stud spacing is wider on the 5020 than the small huskys, includes, 340, 345, 350, 351 353, 346, 357, 359, 455, and 460 maybe others.

Thank you for checking. As my options dwindle, I still got a few things I'm going to try. With replacement parts as cheap as they are on this thing, it's a good platform to gain experience.

I know this sounds like a silly question. But, only dumb question is the one you don't ask.

What options are there for the bottom gasket when you remove the bottom one? I have my normal list of suspects. But, I'm looking to be sure before I make a mess of things.

Thank you everyone.

?

The saw you are talking about is a clam shell design. There is no base gasket to remove. But if it did most guys will use loctite 518, permatex moto seal or derko.

Thank you. I haven't torn it apart yet. If you cant tell.

No worries. I have the poulan version of that saw. It's fair enough for what it is. I didn't gain much on it, but it's not something I use often. So I didn't go super far into it.

Good luck Sir.

Thanks. I'm doing a lot of information gathering. Some of it pertains to this. Some of it for the next bunch. I've got ideas, engineers and machinists. We'll see.

I got a couple scored 4218 in a box need new pistons and carb kits. Got one of those Oregon powersharp blades with the sharping attachment seems like a pretty cool idea. I pulled the cylinders off was shocked to see plastic in there.

There is plastic inside the cylinder?

They can be good cheap fun for starting out with and will cut better than anybody that's never tried one can comprehend.

Spend some money on refreshing the fuel system, new filters and properly functioning carburetor along with a good sharp chain...

Yes

Tear down began tonight. RUST! On the pto and flywheel side bearings. Ordering those in the morning. I feel movement in the wrist pin. I'll order one of those too. Sounds mundane to most. But, for me and my 11 yo son. We're having a blast.

So how exactly would you get in there and with what? I'm assuming a hand file if some sorts. Tips, tricks?

Get yourself a needle file set and one or more of them will be able to get in there to file it out.

Yup! I lost my extra piston & cylinder when I moved, so can not show you.
Maybe Stumpshot will post a pic of his when it's apart.

No can do, saw has left the building long time ago now.

Thanks everyone the help. I'm learning a lot getting my hands dirty.

I went to a local hardware store and they had a file that fit. I now have a quarter of a key in timing advance. Now I got to figure our how to seal up the clamshell when the parts get here.

 

[I Know Something]

So. Porting time. I've never found an "exact" amount you should do. Exhaust side. Is there a rule of thumb? A certain percent on exhaust side port to exhaust side piston skirt ratio? I'm not certain. Please help.

 

[huskihl]

Up to 65% of the bore diameter if the skirts and ring locating pins allow it. But stay at least a mm or 2 inside the skirt to seal off the port
