    Poulan wants to keep their ways & means a secret, but I know the information is out there. What is the correct adjustment procedure for their pro model ?

    1-1/4 turns out on both high and low screws from my experience.

    Poulan carburetor settings

    yeah, I did that, but the saw has compression problems as well so I'm at square 2 with it now. Thx for the help. Mike

    keeping trade secrets

    I understand the need to promote your own certified dealers, but not for carburetor settings. THAT'S TAKING IT TO ANOTHER LEVEL, like the basement.

    The correct procedure for adjusting any carburetor on any saw involves a little bit of experience. I have found that "canned" adjustments rarely are optimum. Many times the correct adjustments are outside the range of the limiters on newer saws, especially if the thing has been sitting and the carb isn't squeaky clean. It needs to be tuned so that it is just for stroking in the cut. You can search on here and find quite a bit. If you have low compression, though (very common on these) there is no adjustment on the carb that will fix that.

    I am no doubt green

    Around saw & trees, but expect to learn enough to be able to break down my own when needs be. It might take me a couple of years, maybe more. It'll be time well spent.

    Thx. / Mike

    Well yes it's good to promote there dealers, but then there's that PITA thing called the EPA, federal laws plus maybe inexperianced carb tuners who will end up smoking there saw then, maybe go badmouthing there company and such.

    smoking machines

    I could have smoked this one on a 40in. pine trunk. Not by resetting the carb. That sap gets to be like concrete in a few years. So maybe I qualify as one of those complaining but I still think that if you buy a particular machine the company should do all it can to assist you in the mainteance of it. Not charge an arm and a leg to so. Maybe I;m cheap.

    Yep a 40" tree, a hot day, maybe dull chain with a 40cc saw could be enough to smoke it.

    Thats OK, like I tried to say blame Poulan for not providing info, but try to get that same info from the other manufactures then come back here and tell us what you find.

    Are you asking about the screw setting, OR ...

    ...About their :censored: tool that you need to actually turn the darn screws?

    Assuming the latter, they did it to appease the EPA.

    They also tell their dealers to not sell the :censored: tool to customers. IIRC, the part # is 530 03 55 60. I got one from amazon. Sears parts direct claims to have them too.

    The other option is to cut slots in the carb screws so that a regular screwdriver can be used.

    Once you can turn the screws, www.madsens1.com can tell you how to turn them--follow the saw tuning links.

    Hope that helps!

    PPine

    PS: I don't care if they call it "PRO"--it's a low-end saw in reality.

    carburetor tool 4 Poulan pro

    I was asking about the settings themselves. I picked up one of the splined tools online as well. Thinking that maybe Poulan had some special procedure for their newer machines. Thx for the info. Mike

    The saw was likely smoked by either a lean mixture, or an air leak. It is a chainsaw!! It should be able to run at full throttle under load. The size of the tree being cut is irrelevant. If you didn't change the carb settings, they may have been too lean from the factory, or it may have been partially gummed up from sitting. I have also seen the intakes crack on those a time or two.

    Hi PPine,
    Thanks for the help. And I agree with your sentiments on this being a pro saw. No pro would tolerate having to adjust the chain between every tank of fuel.

    I have a 4620AVX and wonder what the D stands for on your 4620AVXD.

    I got the tool from ebay and adjusted the high speed mix because I thought the saw lacked power. A little pressure on the bar and it would slow to the point where the chain stopped. I leaned it out a bit and it made a world of difference. Now I worry that I could have set it too lean. :confused: I do recall seeing in the Official Saw Tuning thread that the saw lacks power if tuned too lean, so I hope I'm OK.

    BTW, I got the tool from ebay seller "mowers4u" and this is the tool for the 4620AVX: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=280351588986&ssPageName=ADME:B:EOIBSA:US:1123 I got a link from this seller from someone else on this site and found that he answers email and ships quickly. I'm not sure if that is the right tool for the 4218 but you could ask.

    if the saw is under warranty why not take it to the dealer you the consumer dont have to pay a cent for a carb adjust job poulan pays the dealer for the repair etc. which reminds me i need to go work on a trimmer for a customer so i can get paid from poulan

    Hello,
    Home depot had what should be new one on saw for $100. My buddy bought one. In typical EPA fashion the thing wont even run out of the box. I had to de-EPA-afy the carb screws with a hack saw to make it run. This is one of the those so-called strato motors with the twin butter-flys on the carb. I've never messed with one but I'm assuming you want it four stroking on the top end like any other saw. The thing is new so I don't want to give it hell just yet so I'm gonna have to wait until we go cut some more fire wood to set it up. I figure for $100 new you cant go wrong.

    If you are talking about the 4218avx, it has the Zama W26B carb. The upper butterfly can be sticky and stick open, preventing a start. Put some oil on the shaft and you are good to go. Adjust the carb at full throttle / no load for just a little burrble / 4 stroking. 40:1 on the mix, 89 or greater octane. Put a Bailey's 30lp chain on it. You will find the gas cap and maybe the oil cap start to tighten up after a while. The saw is a good runner and has an inboard clutch. It is a cheap saw but with proper setup, will get the job done.
