Stihl MS 250 carb gasket

[Timothy]

I unbolted the plastic piece that holds the air filter to wash it, not realizing the same bolts hold the carb on. after putting it back on, i noticed a sucking sound when pulling the starter cord except with choke off and throttle trigger engaged, i do not remember if it made that sound before or not. i removed carb and wiped off every mating surface between it and the saw, put it back on, it still makes the sound. the gasket has a small 2 to 4 mm tear next to a bolt hole, i made a new gasket from paperboard, put it on, still the sound. at this point i don't know what to do except use washers and bypass the plastic piece in order to bolt the carb on tighter, and check for the sound.

Sucking sounds are pretty normal.

Especially with Stihls. (Just kidding Glen)

haha. i'm just afraid to run it and risk damage due to an air leak.

Timothy,

That sucking sound is the sound of stihl taking more money than they should have for the saw. You just couldn't hear it when making your purchase at the dealer..... LOL

By the way. Did you get a 15 day no questions axed satisfaction guarrantee? Maybe you can still take it back and get a Husqvarna. See below for Husqvarna's policy.
Crown Commitment
If you are not completely satisfied after purchasing one of our products, return it to the selling retailer any time during the first 15 days for a replacement Husqvarna product of equal or greater value.

Just a thought!

Timothy,
There is usually a different sound when the choke is applied.
Does the tear go from the stud inward and make a complete tear so that air could get from the stud hole to the inside of the carb? I'd replace that gasket just on principle. If not, don't worry about it.

Timothy,

Pay no attention whatsoever to Woodtick.  It says he's a senior member under his username but that's obviously not the case.

You don't need to routinely remove the filter housing, as you've discovered.  This is a new saw, correct?  It really would be best to stop in to the dealer and let the mechanic take a quick look at it so that it can remain under warranty.

While you are there get a gasket, if you are good at making them and have right material, then it is ok. But if you don't feel sure about what you have done, let them have a look, and say what you told here. I do not think it will cost you much.
If you get them to show a thing or to that will be wort a lot of gaskets.

the spark plug boot came off the wire today, i'll take it to the dealer this week if i get a chance, i hope that's covered under warranty. the tear is all the way to the inside of the stud hole. when i take it in i'll put the original gasket back on, pour out the gas, and clean the spark plug since i've been using 40-1 mix, i don't want them to have any excuses not to deal with it, i called them today asking if it would be covered under warranty, the guy asked why it would need a gasket and spark plug wire, didn't sound as freindly as when i bought it. if they don't fix it i'll see if a Stihl dealer in a different city can help.

I don't know why you'd expect something you did to the saw to be covered under warranty.  My point was that it should be given a clean bill of health from a qualified mechanic.

Just think what might happen in a situation like this with a mail-order saw...

Didn't your selling dealer show you how to clean the air filter and perform basic maint.? You know, show you how to properly tighten the chain? How and how often to flip your bar? What to look for in a worn sprocket? Or did they just start the saw rev it a few times and hand it to you like the UPS man? Let us know.

Once again,the dealer issue comes up.First,Stihl makes a fine product,rather pricey,however.Not all dealers,are good people to deal with.We,in this area,have several,some good,some not too good,one is excellent.The one that is par-excellant,started as general go-fer,while in high school,for a lawn and garden shop[ no just saw shops,here in the big corn field].This gent,bought out his employer,and built it into the largest Toro dealership,in the USA.They will bent over backwards,with help.parts etc.,weather it's a new 880,or a $3.00 gasket.Given the choice,which one would you go to ?Oh,and they also are good with old McCulloch parts,if they have them.How about that.
