Thread: Poulan 25DS?

I am only trying to help too Mark.....wasn't quarreling with you or trying to say one way is better than another....was just pointing out disadvantages of different ways which I have learned the hard way.

I removed the welch plug. It is very clean under there, looked through all the ports with an Ottoscope they are clean too.

What is the best way to put the new plug in, I was thinking an arbor press. DO I use a tool larger than the plug so when I contact the carb floor it stops or do I use a smaller than the plug diameter tool and push until flat?

I posted this in the Poulan thread but so many people post there it gets buried in 3.14 nanoseconds so I will try here.

I got my new spring from Calvin and after finally reading the instructions in plain english on the cover on "how to operate" here is what I get.

I choke it and hold the throttle. It pops right off, then I shut the choke off and while holding the trigger wide open it runs like crap. If I let off the throttle a little it winds up to very high RPMs (like my dad's 357XP which rips). Anyway when I let off the throttle it still runs very fast just like I am giving it gas on a normal saw. Fuel filter and line are new, carb is rebuilt with both needles 1 1/4 backed out, air filter new, spark plug is new...

Any ideas?

Sometimes the 1 1/4 turns open on the low is too lean,open it 2 full turns and go from there.

Tries this, didn't do anything so I screwed it all the way in and idel finally came down at about 1/8 turn out then died.

Do you have the needles in the right holes?The low usually has a sharper point than the high.Will it idle at all?

i just found an oold poulan 25da in ym fathers garage. he said his brother bought it for there father and it was barely used. my father also said that it hasnt been ran in like 10 or so years and gave it to me. it needs a fuel line which will be done tomorro. the saw was bone dry in the tank so im not sure if the carb will need a rebuild or not.

good post,, lots of info and help,, way to go guys,,,
1 1/4 or so is a place to start with teh carb settings, i found my saw was a little touchy to get set just right after i rebuilt the carb , but once its set right, it runs great,,, get the saw to start and set teh lo and idle speed just right, take small turns on teh screws, and go slow, if teh carb is rebuilt, clean, and assembled in teh right order, it should start and idle good,,, when you have teh lo/idle set,, then set the hi speed,, you may have to go back and tweak teh lo again to get get the carb set perfect,,,, lots of carb tuning threads on here, and the walbro site is very good,,,
good luck...

I think it's an air leak...

i hope not, but if it doesn't slow down with teh throttle, thats probably what it is,, is teh saw in overall good condition, or pretty beat? also, did you have trouble getting teh fuel line in? could it have gotten damaged while you were installing it? is teh fuel filter staying submerged?,, just a couple more thoughts..

The fuel line went in pretty good. The saw is pretty beat (paint missing, dings etc). I think it would be a fun little saw but I have to rip it all the way down. The throttle has no effect once it is running. I t just winds up like banshee.

yep, its probably got a leak somewhere,, if its pretty beat, maybe teh seals are leaking... well, good luck with it, it is a fun saw,, mine was almost new when i found it, and i used it for firewood for a year or so before i got bigger saws...
