stihl 024 issues

[h2obio]

Hi all, a friend gave me his older saw and it will fire for a sec if I shoot fuel in the carb, but then dies. Any ideas?

Thanks!

If it's a used saw with unknown past id replace the fuel line and filter as well as the impulse line. Clean and rebuild the carb and then start a process to see if it will run. Pulling the muffler cover would also be on the list to check that the p/c are in good shape.

I do all the above but sometimes it's easier just to replace the carb assuming the engine's compression is still good.. If the engine's compression is a dead puppy, there is nothing that will work before doing a top-end rebuild. Just MHO. Here's one of the four 024 AV's that I converted to an 026 AV:

It can be done. After seven years, this saw still runs with 026 power.

Have you rebuilt the carby if not I think I would start there and
make sure you give it a good clean probably in an ultrasonic cleaner.

As someone else mentioned, check compression first, also pull the muffler and look at the piston, just because it has decent compression doesn't always mean the piston is not damaged. If all of that is good then pressure test the fuel line. The older carbs on the older saws were a lot more forgiving than the newer ones so I would try a crab kit before replacing the carb. If you have the equipment I would also do a leak-down test to check for intake leaks.
