The O66 and O64 are basically the same saw just with a different bar option. All of the parts are interchangeable. If you need parts the serial number is what you will refer to. Also taking your saw with you to the parts store is always recommended.

Spray a little starter fluid down the carburator . It is starts then is is a fuel problem. Most likely a gummed up carburator. Remove and clean .

SOURCE: tunning specification for a stihl 028 chainsaw?

I'm not sure there are any "endorsed" tuning specs from Stihl as weather, temperature, fuel quality etc all contribute to engine performance.
Pictures of all types are all over the web.

As for the carb tuning procedure, maybe I can help?

Start with fresh fuel, all filters clean, and bar and chain installed. Also, fill the chain oil tank with bar/chain oil and VERIFY that the chain oiler works properly.
Initial fuel mixture settings (the H and L screws) should be 1.5 - 2 complete revolutions counter clockwise from lightly seated. Sight the carb's throttle plate and adjust idle screw counter clockwise until the plate stops moving.(Throttle closed completely.) Then go back clockwise 3 complete revolutions. This will produce an acceptable startup condition on a HEALTHY saw.
Clamp the bar in a STURDY bench vise and roll the chain with the shank of a screwdriver to verify it is clear. BE SAFE!
Choke the saw and pull the starter rope until the engine "burps".
NOTE: If no burp after 6 pulls, stop! Something is wrong.
After the burp, set choke to half and pull starter until it runs. The settings I gave should produce a slightly rich condition and a slightly high idle. (Chain will be in motion!)

Blip the throttle trigger and idle it down just enough to keep it running during the tune procedure.
Step 1) Using the "L" screw (closest to the engine), turn it clockwise until the engine smooths out or possibly increases RPM. Back it out slightly until the engine has a slight "LOPE" sound to it. (Like a drag car on nitro).
Step 2) Accelerate the engine to full throttle and go to the "H" screw (closest to the air filter) and slowly turn it clockwise and note the RPM increase. There will come a point when the saw will "Top-Out" and loose power. Not even enough power to turn an maintain empty chain's RPM! Go back counter clockwise to the edge of that point, and counter clockwise another fourth (1/4) revolution.
Step 3) Idle the saw back down. Again go to the "L" screw and repeat Step 1.
Step 4) Repeat Step 2.
Step 5) Idle the saw down until the chain stops moving completely. NOTE: Don't settle for a "crawling chain" condition. If the steps above are performed well and all else is healthy, you should be able to idle the engine down to a ridiculously low RPM and it will not shut off.

Hope this helps,

SOURCE: how do i find the model number on my poulan

If you entered the 42CC 18" it is a PP4218(AV, AVHD or AVL) Gas Saw Type 2. The letters after the 18 correspond to the type of chain tensioning system.
The dash number of your serial number is the type. Match the "Handle, Chassis and Bar Assembly" with your saw to complete the IPL.
An OM and less detailed IPL for your saw can be found here:
Type just the model numbers (choose the suffix after the list is provided).

If you have more questions or need additional help please reply below and I will get back to you. Thank you for using FixYa and Good Luck. HTH

Stihl chainsaw Serial number 116898867

Sabrina, I think that answer is only going to come from Stihl themselves in Germany. There are endless requests on forums and question sites asking just that without an answer. If I ever get a definitive chart you can be sure I'll publish it. The main block to this type of info comes from Stihl themselves who never publish parts lists or handbooks by making factory info a dealer domain. I know there are thousands of publications out there on the web, I have over 50 Stihl parts lists on file but they do protect their dealers.

Where is the "machine number" on a Stihl chainsaw?

Machine number? Do you mean model number? The serial number is stamped under the saw in the front.

Stihl power pruner serial number

The serial numbers on the FS130, HL90K,HT101 and BG55 would be on stickers if they are still there... The MS250 serial numbers are located on a 'flat' by the side of the exhaust and sprocket cover. (depending on the year of manafacture)

How to find date of manufacture for Stihl chainsaw ???? # on handle sticker is not DOM--

The date of Manufacture is not posted on a Stihl chainsaw. Only a dealer can tell you that information, and Stihl doesn't like to let consumers know this information, as from a selling point of view, model year can't be used to negotiate a lower price (like last year's car model...still new, but you get a lower price because it's not the current year.) You may find a dealer that will look up the serial number and tell you, but not always is it possible.

Looking for a manual for a stihl pole power saw

Your local Stihl dealer can order the manual for you. It might be free or there could be a small charge for shipping. Either way, it's worth having the manual and Stihl WANTS you to have the manual. Be sure to have your model number and serial number with you when you go to the dealer.
