Got another stubborn one.. Stihl 017

Post the part number for the flywheel you need when you figure it out.

Think of how far ahead you would be if you had the use of a timing light.

I kind of knew by pulling the starter that it wasn't firing, as I mentioned in the posts. Usually they'll do something; this acted like the ignition was off, even though it had a good spark. I put the new carb on it anyway because the old one wasn't adjustable; I seldom put the original non-adjustable carb back on them. I have a few old flywheels around here; probably try one or two of them and see what happens.

I have another really old 017 here that does run. I'll see if the numbers are readable on it. Like said, I'm gonna set this one aside for a few days, got some others right now to work on. I hope they're a little easier than the last couple.

Of course when you work on different saws and take several apart at the same time I suppose you might grab a wrong flywheel and put it on. I didn't do this but I think I remember once I had an 017 or 018 with a ms250 flywheel on it. It came in that way. It looked okay but the spark was about 45 degrees off. I suppose the previous "mechanic" thought that if it would fit then it would work.

Shot in the dark, but I have a box of parts for those type saws that were ordered and never picked up.

I am happy to see you at least have a possible path to follow now good luck.

Luck is what I need. When they bring saws to me to be worked on you never know what you'll find. The one thing that is consistent is they're all filthy!

I have 2 other 017-018 saws here, one runs. I may take the ignition off the running one and compare them.

You need to check that the motor is tight in the housing, the case sealant is not leaking, and intake boot is not split or out of plate. Probe the pulse passage and check to see it is open and actually delivering a pulse.
As far as spark, not likely. Yes I could be wrong, but you would have a really rare one there.
Is the plug wet? With all the cranking and addition of fuel, it should be really flooded.
Try one more thing- pull the plug, crank the saw over holding it upside down. and the throttle wide open. Then leave the plug out, set it upright and walk away for a couple days.
When you return, put the plug back in. Crank it a few times with the choke off but on fast idle. If no start, try it like any saw- choke on, pull no more than 4 times, choke off and fast idle, pull away.
Restarted more than a few saws doing this.

And I'll bet especially a 250. Easiest saw to flood I have ever seen. jmho OT

If it does not leak enough that you can tell by running it, then why ?

Cause some Stihl class told you to ?

I have cranked the high needle up and finished a job with half the plastic part of the seal gone.

Jesus. Work on some saws.

Me thinks you might have your shorts in a wad? But that's okay. lmao OT

I kind of agree with you but this saw has never been started by me, I just pull and pull and nothing happens, like the ignition is turned off but it's not.
I didn't work on anything today but I did notice the saw has the new carburetor on it and everything is attached. I noticed on my receipt that I also bought an ignition module at the same time but it is not on the saw. If I can locate it I'll install it and see if anything happens.

"If I can locate it" Should be near the flywheel. lmao I jest. OT
