Farmtech … no problems so far.
Same here but I've noticed that there advanced from the get go.Farmtech … no problems so far.
Lol.just make sure not to advance the timing to much the power of the saw will start to fall and start to ping but so far I think you're doing good on what your doing I just don't want to see you kill a saw if it can be avoided.My mind is boiling 90 MPH right now, I'm questioning lots of things I've done (or not) … timing advance … cylinder porting … I just wish I had a crystal ball!
Plan to test lots of stuff at the CT GTG.
Apsalootly.I've not had any trouble with them, but I always use an OEM piston pin bearing, and I flush all my Asian bearings with WD-40 before I even turn them. They often have debris in them.
Unless your pockets are deep, I would go for it!
Another caution … the cases are sometimes not "correct" for the chain adjuster. Their adjuster often has an over sized large gear that will not fit into the case.
To get it to work (OEM will sometimes not work here) I chuck the over sized gear in a drill and run it against a file till it fits in the case. The everything seems to work OK.
The good part is their low cost allows a lot of broken OEM saws to come back to life.
The 350/346 I built recently didn’t seem to like timing advanced. Probably already close to optimal stock. Every saw can be different for sure.Lol.just make sure not to advance the timing to much the power of the saw will start to fall and start to ping but so far I think you're doing good on what your doing I just don't want to see you kill a saw if it can be avoided.
Yea there all different for sure I always check before I even attempted messing with the timing.The 350/346 I built recently didn’t seem to like timing advanced. Probably already close to optimal stock. Every saw can be different for sure.
I have heard that a lot of Husky's don't like it, but most Stihl's need it. I may even start giving many of my saws even more.
When I advanced the 064 it came alive. Only did it about .015 since the saw has no decomp and I don’t want to kill the starter. Most Stihls really seem to benefit from it for some reason.I resisted advancing the timing on my MM'd 044 for quite some time because it ran so well. Once I advanced the timing, I gotta admit it really woke up.
I think it was Mitch that was showing the timing advance on saws a while back. Like in 2011 or so on another forum before he got sick of all of us The Echo's were super aggressive with their ignition set up. So a rather lackluster saw would pull a long bar in wood without bogging. I wouldn't say many were fast, but they would easily just chug right along with conservative factory porting and carbs. Timing makes a big difference.

Yeh I totally agree, I’ve played with my stihl saws a bit, but when I’ve advanced the timing they had more torque and cutting speed, less bogging in the cut when leaned on a bit.
I'm sure there’s some maths somewhere that could prove it, ie piston speed, ignition time and fuel burn rate....and powa..... but I’m not a mathematical enough to even go there.
Just askin, Is that right what i Read above completely burntThere's loads of stuff on line. Like Randy, I used to mess around with muscle car engines back in the day. Most of it basically says you want complete burn(well, as complete as possible) around 20* ATDC, and not so much burn you get detonation or push back as the piston arrives BTDC. One way to test is to set the engine up to detonate, then pull back. I did that with an old pre digital Echo(and have done so on god knows how many V8's). As is sort of obvious - this can vary wildly depending on the set up, and even from the same engine to another of the same depending on fuel, deposits, manufacturing variances, build variances, etc etc. And if you get too carried away, you can damage your engine doing it as well.
Some manufacturers will be more aggressive than others here.
