I have a stihl 028 chain saw it has spark compression and gas but it wont start or even fire what can i do?

Have you checked the compression on the cyl. A saw that old may have lost compression and also have you checked the muffler to be sure it is not plugged. I base this on you saying you have fire to the plug.

You obviously have a fuel problem. Clean carby jets and also check restrictor in fuel line.

General rule is to tighten it by hand, then turn it with a ratchet another 1/8 to 1/4 turn.

check your abc's of engines first
(intake,fuel) substitute a tiny amount of raw gas in carb intake to see if it springs to life !
(compression) -pull rope slowly to "feel" the piston move up in cylinder to meet resistance , then down again
(combustion,spark) - remove spark plug from engine and place nearby the hole (don't hold it !!!) and pull saw over briskly look for spark near tip of plug

is it getting gas?is the fuel filter plugged?does it kick if you drop some fuel into the carb?

Remove the plug and then plug into plug wire. With the spark plug laying on top of engine pull the recoil a couple times and you should see spark at the plug. If all is good and there is the proper mixture of gas/oil ratio in saw then >>With trigger depressed fully and choke on, pull until it fires and then shove the choke in. /////If no spark and the saw is new, I would return to retailer.

Any other manufacturer I would provide a link to an IPL. Stihl considers them proprietary.

There are two idle screws one high, and one low. Your high adjustment idle screw needs to be adjusted.
