Working on a poulan pro 5020

Had a guy drop off his almost new pp 5020 av that got pinched while felling a tree. So as I have it in the shop I will see just how she can run.

 

I vote for muffler mod it, base gasket delete, and port it, then pizz rev it like you stole it! Oh yeah and pics and video or it didn't happen!

 

I will at least do a video review. I did get the bar and chain freed up but he didn't do it any favors.
The Oregon vangard chain is kinda interesting.

 

I will try and upload a video over night.

 

Vanguard chain is no bueno. Good for stumping though.

 

Well I got the video edited. Now if my Internet will let me upload it. 16 min of rambling. But it does feature a hot chick in a Carhart and flip flops.

 

The 5020 is a clamshell. The muffler mod does help it though. It is also a strato saw so not an easy saw to port.

 

I didn't know they were a clamshell. Scratch the gasket delete. They can still have the ports massaged though.

 

My Internet sucks!

 

Ok don't wait up boys. We are only at 4%. I will be lucky if it uploads by morning. Feel free to stock my you tube channel if you like.

 

I tried to modify one by porting and bringing up the compression. I messed up on it and it would not run for crap. I bought another cylinder knowing what mistakes I made but have not got around to working on it again.

 

Here is a cutting video. The other video has not uploaded yet. I will try when I go to town and see if I can get it on.

 

Did you find the specs ? I didn't find them in the manual
I found, Idle 3000, max 9000 rpm

 

Ya I found she responded well close to a 3000 idle. Not sure max I found she cuts real good just a hair on the rich side. Which is odd alot of stratos like a bit lean

 

Ok after 14 hrs and 3 tries here is the review video with the hottie in a Carhart and flip flops. Lol so at least give the long winded video a thumbs up for the effort.

 

I'm not sure there is much you can do to improve compression. The ports can be widened some to help it breath better. I did a ms 180 like that. I got decent gains over just the muffler mod.

 

Widening the intake port was one of the things I did wrong. Because it is a strato design the piston has some special machining done to it and when I widen the intake port a little I got into the maching on the piston. You can widen the intake but by very little. I was going to move the pockets for the bearings and seals up by .020" for the compression but I think I took it to far and created an air leak. I have done this before on a Poulan 295 and the saw turned out great but on the 5020 I need to use a little more patients on it next time.

 

Yes I wasn't able to widen the intake on the 180 much as its a strato as well. I was able to get the exhaust a bit wider though. It was a fun little saw, but the clamshell design makes you work hard for a little bit of gain. Never worked on a 5020.
