I don't know,the saw I'm using is around 200 or 210 I'm guessing I've never checked it. I think it will vary from saw to saw, flywheels and coils will vary from saw to saw.
IMO for best performance every saw will need to be individually tweaked for ignition timing and tested. A few I did needed to be set back with a long bar and full comp chain. They were not from this model or blend there of. 60-75 cc class running a bar not recommended for that size. I just try to do what is asked of me by the saws owner and not what is recommended
If it can be done it is always worth trying.
Anybody else ever put serious thought into why almost every 066 and 660 cylinder is timed different? No way they changed them intentionally that often.
I can't recall ever seeing 2 alike,lots close but not the same. It's not possible to change castings that much.
Good question! I got nuttin...
My guess would be that there's a lot of moulds used in the manufacturing process. Each one is just a shade different but still in spec. So out the door they go. I'd bet that Stihl never gave it a thought that someone would actually be checking the timing on them.
How could they F-up that bad??? I would think that is the most critical of all manufacturing processes is to get the "mold" or core shift right? no?... Can't make chicken salad with chicken *s-word.
The silly little muffler hole makes all that silly stuff like port timing go away in a big hurry. Jason should try his worst runners out with a stock muffler and see if they revert back to a near stock running saw. I'm going to try it with this 044-046 builds coming up. Something keeps telling me to give that a try. You can not get out what you can not get it.
I'd drive a little screwdriver in it on the edge and pop it out then straighten the edge back up.
I haven't done it in 20 years but back then I would make or reuse everything I could and I learned a lot from doing that.
Lots of time the pto side seal can be popped out with little damage to it.
I'm with you there.
Case in point. my first 029 build was two junkers in a crate with one complete burnt saw. I bought nothing but a set of rings and had some sealer handy. I needed to learn what was what and the whys of why it was what it is. Learned more about saws that day than ever before.
People laugh when you said, "I reuse", I did not. I know the lesson you learned by doing the same things when we were youngins. We had no resources and were broke to boot. If you had money and resources than you must have been looking for a learning experience like I was back then. I was cheap with my own toys. I paid the price sometimes with scattered or melted parts. The study of used or trashed parts is lost in most of todays teaching methods. That's how we got too many parts changers and not enough good diagnostic people in the repair industry these days. Most general repair mechanics today would not know that most used flywheel side seals are quite serviceable because they usually don't get looked at or studied at all. Rip out, replace, next
I'd bet some of those seals you swapped around are still in service today
