Nik's Poulan Thread

Thanks again.

That 4620 is too nice to part out so I may just MM/TA as is.

Provided the 255 is repairable, I’ll scrounge up a chain brake and give it to a friend.

I understand the 4620 MM but what is the TA ?

Timing Advance.
But in the poulan threads it could also be the Tim Allan .

I was wondering how was going to do a Tim Allen myself.

Well I am taking this 3400 and changing it to 3700. I have NOS rings for it so those will go on it too. So today I got the piston switched over and lowered the squish to .022". I also opened up the plastic intake manifold. So next will be to port the cylinder and modify the muffler.

Removing old piston.

3700 piston installed with the new rings laying there. I left them off until I got the squish set.

Did u simply sand the cylinder base or use some other more exotic method? If sanded how much surface do u estimate you removed?

This PP445 has been listed on my website and group. If someone is wanting to add a 71cc quad port to their collection just PM me.

These pics is saw still dirty from use before selling the full wrap handle off it to a guy that wanted both full wrap set ups.

IMO and others it is the hardest to find and the best one in series. I have 4 of them but only 2 runners in 445. This one has the best covers.

Oh noticed I have my husky flippy cap on gas. I will put the oem right caps.

I sanded the base down. I probably removed .012 to .015".

Cylinder is on and the muff mod is done. I am waiting on carb kit so it can be done and then I will finish it off.

Are you planning to use a 4000 starter, steel inserted pulley hub & FW?

I’ve busted the original plastic 3400 series teeth clean off the pulleys on high compression squish mods like that...just saying.

I see a little craftsman red on that cylinder, same as mine.

When I first got the 4000 cylinder kit to test I took a 3400 as the starting saw. It took me 8 or 10 pulls and the 3400 starter teeth were gone so I changed it over to a 4000 set I had stashed.

That s quite an exhaust outlet. Wonder how loud it will be.

He won’t be able to sneak up on anyone but with a side exit it won’t be nearly as loud as a front exit.

I will start out with the 3400 starter. If it breaks I will upgrade to the 4000.

Yep the donor saw for this was a red craftsman.

It will be loud. I can put a spark arrestor in if need be but for now it is really opened up inside.

No 4000 flys left but a new and used pulley if needed.

Rings long gone.
