Nik's Poulan Thread

Keep the fitting and use it for another Poulan. Use the correct fitting on the 4200 that you have. I'm not sure why you would not use it.
The little piece of tubing that was on the 4200 vent was smaller than the little tube you get with a can of WD40.
As for the muffler, it doesn't come apart.
Have a look at the manual and IPL. You would find them helpful.

I see your fuel line is clear. Is that plain vinyl? If it is it will be hard and brittle in a month or two. It would be better if you used Tygon.

Thanks Tim, I'm just going to order the right vent/relief part for the 4200. The fuel line is replacement line for saws, trimmers, etc which I thought would be fine. Is Tygon a brand of fuel line?

Got the fuel line replaced last night

If that is the same clear fuel line I tried out back in 05-08 you will get 1 season out of it and will shrink and harden up. Be careful if it is and keep a eye on it.

Ok well I guess ill get some Tygon fuel line then. Don't want have to do it again if I can avoid it.

Different tygon lines too. Were testing some out on a different chainsaw repair site. There is also another new one getting ready to be tested as soon as it comes in.

Tygon (is a brand of line) is fuel resistant and stays flexible for a long time. Cheap lines get hard and crack and break.

Well here's what I'm working with. Piston looks great except one for spot on the front.

Looks like you caught it just in time, carbon build up and broke loose to me. Lets see the after

Plans changed last night and all I had time to do was disassemble everything. But on that note, how is the best way to get the carbon out of the rounded top part of the cylinder?
I have to work late tonight but I'm hoping to get everything cleaned up tomorrow and reassembled.

Oven cleaner or sodium hydroxide

Ok thanks, Tim mentioned oven cleaner as well, I just didn't know if there was brush or something that works well to get down into that area.

Use a stick like a piece of dowel and cut a chisel point on it. When you spray the cleaner on the carbon will come off quite easily I don't know how badly your piston is scored but do make sure there is no aluminum pick up on your cylinder. If there is, you need to get it off or you will ruin that cylinder. You can get pistons for the saw for around $40 plus rings but the cylinders are hard to come by.
Make sure the rings aren't pinched where the scoring is.
I think you will be impressed by the power that 69 cc saw has.

Thanks for the good info Tim. If all goes as planned, it should get cleaned up tomorrow and put back together.

This oven cleaner spray I got says not to use one aluminum or chrome. Still ok to use on this cylinder and piston?

 

[Acornhill]

Do a test area and don't leave it on, I use a q tip to rub it around and wash the cylinder in soap and water after.

 

[Acornhill]

I use emory cloth to rub the transfer areas

 

[blk05crew]

Thank you sir!

 

[blk05crew]

I use emory cloth to rub the transfer areas

When you say transfer areas are you talking about the little bit of scoring on the piston? Can I use steel wool on that area that is scored a little bit?

 

[Acornhill]

Very fine maybe, l like emory because it collects the transfer in the openings

 

[blk05crew]

Ok I'll do that thanks. I've just never done this before and I don't want to screw anything up!
