Nik's Poulan Thread

[drumbum]

Well I hate getting old. New seals didn't help the 5020. I started racking my brain thinking what else could cause this symptom.( Acting weird when leaned forward over a log to cut )
Only other thing I can think would be a weak fuel line that kinks when the weight of the filter pulls it . Then I thought , surely I checked that or changed it???!!! Or did I maybe do a quick visual and thought all looked good and it seems to be a low hour saw so it's probably ok??!!!! Could not remember for the life of me.

This mod may not fix your issue,....but a necessary mod.

Get some black nylon strap that looks close to what was used to limit anti vibe springs on saw.
Use an old chain file and heat up the pointy end with a propane torch and use to cut a length about 42mm. Melt a hole in both ends.
Place strap between upper rear handle screw and the large head screw under the choke.

zat make sense?

Partner used that on some of their AV. Even poulan on the front lower AV on some saws.

To show what I think he is talking about.

What does that accomplish? I don't have the saw in front of me and I'm having trouble envisioning it.
Thanks!

The 5020 is a strato design.

The spring antivibe design is flawed in the fact that when using the top of the bar, the air throat of the carb closes partially,....****** up the mixture and hence the running of the saw.
Some don't show it immediately,....but with just a little time they do.

Take a look. Pull your air filter cover and air filter off the non running saw and put the bar in different positions to flex the antivibe while you have the throttle wide open and watch the top throat of the carb. Typically it shows when up cutting, but also when just the weight of the saw flexes the springs (IIRC).

Are you clear on my instructions about the making and fitment of the strap?

FWIW, I have 4 of these saws and I like them. 2 with 16" 3/8 and 2 with 18" .325
Slightly de tuned (on paper?) and engineered to be heavy (zinc alloy clutch cover) so as to differentiate from the premium brand.

Thanks for the details. I think I get it now and will give it a whirl after deer season. I actually like the saw minus this strange issue.
