Need help with my Stihl 024

[Mike(nj)]

Got it in a box taken apart from my father. Turns out in needed a piston & rings which I got off ebay (golf kit). Put it all together and it runs but not great. I'm not sure how to tune a saw. Looks like the air screws (H & L)should be 1 turn out from seated?? At least thats what it says on the plastice cover. When I set them at 1 turn out it won't run?? If I turn them 3-4 turn out it runs ok but think it should be better. Any idea's?

I took the coil off.......will that affect how it runs?? The plug looks a perfect light brown color.

Should be about one turn out. You either have a whopping air leak, or, a blocked carb... I'm betting on the first. Find the leak or you'll toast the piston

If you have to turn those screws out 3 turns to make it run better you have a air leak. Turning the screws out that far is covering up the leak with a excessive rich fuel mix. Get that saw vac/pressure tested and you will find it probly has bad seals.

Which Tom did not mention is probably what caused the P/C to go in the first place. The P/C weren't the "cause", they were the result of the bad seals.

Tom's a good guy, and really up on his saw mekeniking, but often he gets to excited to finish his story...

+10 on the air leak

what you are doing by having the settings so fat is compensating for the leak enough that it will run however as Lake said,,, wouldnt doubt it if the original problem is still there,,, you would be well served when diagnosing a wrecked P/C to run a crankcase pressure Vac test before tear down,,,

sorry I stepped away from the puter for a minute to freshen my coffe and feed the Dogs!!!!

What a great site!!! Thanks for the quick replys.

OK, now where is the best place to buy the seals? Local dealer, ebay??

 

[ChuckinOhio]

Get em from your dealer if he has them, support the guy trying to make a buck.

If you go internet then at least use an AS sponsor to get parts from.

Use eBay as a source if you just absolutely do not want to spend money at your local dealer.

Before you buy seals... figure out if it is really the seals. And... get a service manual, and then there's the special tools... flywheel puller, seal puller etc.

If it is a seal, then it's most likely to be the flywheels side, and the most difficult to change (without the correct seal puller).

You really need to pressure and vac test the saw. It could be as simple as cylinder base gasket.

and dont for get the intake boot/ carb/fuel and impulse hose,,,,,,,

You guys were right.........crank seals. I took the bar off and sprayed some starting fluid buy the seal behind the flywheel. Idled perfect and then died. And thats with the air screws a 1 full turn open from closed. I'm trying to fix this saw for a little $$ a I can so i'm going to skip getting the manual & tools.

I don't need to split the cases, right? I know some seals on motorcycles have a lip and you need to. I've used picks to remove seals before so i'll try that first.

Thanks again!!!

Nope you don't need to split the case to put in seals. However my freind without the proper tools replacing seals can be a headache. You will need to get the flywheel off, not always that easy without a flywheel puller but can be done. Will need some sort of piston stop as well and alittle know how in putting those seals in correctly. A seal puller would be nice though it can be done without one but not nearly as easy.

You know instead of trying to repair it on the cheap you should think for a moment. The 024 is a nice saw. If you had to replace it today you would have to get the MS260 at the tune of $459.00. That said you have in that 024 a great learning tool if you want to be a chainsaw buff of sort. You could take that one saw and really become quiet good with repairs on all saws. Not telling you what to do but it does seems your fairly insterested in saws. That said do yourself a favor and go to the dealer and get yourself a repair manual and while there ask alot of questions. Most good dealers will help you along with your own project. Hell I even loan out those special tools to guys like you to help them with their projects. So think about it, you wanna just replace the seals or do you wanna become savy with saws, with that one saw you can do both if you want to.
