Pump gas 10% ethanol?

Non-Ethanol

Good up here cant get non e so mine get aviation fuel. I wonder how exactly that carb is governed.

 

[Kensie1988]

I have no clue, I know how it works just not what it looks like to make it work haha, if that makes any sense.

One guy called it a buzz bubble (or something like that), so what happens is under low rpm it is seated and when you give it throttle and it meets a max rpm it shakes open and allows more fuel to flow in to keep it from running lean.

 

[Boomer 87]

Ok i have heard of that so im wondering id that can either be changed or eliminated. Something to ask the poulan guys.

 

[Kensie1988]

Yep, they just informed me a 1/4" diameter disc cut from an aluminum can placed into the bottom of the hole and the brass screw screwed back into the carb on top of the aluminum disc will render the governor mute.

 

[Boomer 87]

There ya go worth a try, now we both know lol

 

[Boomer 87]

You know what a guy needs to make the disc is a set of small leather punches

 

[Kensie1988]

Yep that or he said a handheld single hole paper punch works as well to

The only saws that are running ready to cut is the Stihl and my SXL

I'm using Stihl oil (orange bottle) mixed 50:1

So the Stihl works and the Poulan doesn't. Hmmmmm [emoji57]@Boomer87

 

[Kensie1988]

So I had an epiphany, if that decomp valve was leaking, would it prevent that governed carb from keeping a proper tune?

 

[Boomer 87]

If it were leaking it would be low on compression causing incomplete burn, so in theory yes i think it could

Ok I'm about to start the trek to Texas to pick up those saws, but when I get back I will check compression with and without the decomp, what would you reckon is the best thing to fix it?

 

[Boomer 87]

Mine doesnt have one so not sure how the system works

 

[astnmacgto]

If it's setup like the macs I'm not sure that you can remove them and plug them, It relies on spring pressure to seat the destroking rod in the port.

Whatttt you're coming to Texas??

 

[Kensie1988]

Yep, I'm currently in gladewater

@astnmacgto there is a spring over the decomp so you may be right, how do I fix it if it's bad?

I only have one saw with that style, I'll have to look it over and see if I can come up with a good solution

Thanks!

Those Poulans are always causing problems. Ain't that right @Boomer 87?? Shoulda got another Stihl [emoji23] no don't, someone had to like Poulans and not take all the stihls

My Dad had three Poulans on the farm One in use ,onein shop, one ready to be used or go to shop cause he didn't work on small engines.

 

[Kensie1988]

I want more of the old poulans, especially the countervibes
