At this point In the gas RC boating world we would also try going back to the stock exhaust to see if it resolves this issue. If the exhaust flow is too free flowing or the exhaust expansion is timed wrong, the engine will bog and not create enough back pressure to keep in the fuel to be combusted. This series has been my favorite and I bought a CS590 to play with because of it!

When its not it wont...it acts lean n wont idle. It might idle but wont take fuel n bogs out. Its now having a delayed start. You pull to start n a second or two later it fires n starts. Hope this helps.

Hi tinman watching your videos are like watching one of my favorite TV shows! I'm a mechanic too I work on engines small and big just a thought maybe put a tachometer on the saw see how many RPMS it is running now maybe it is bouncing off the rev limiter. But maybe it needs a different carb now. Would be interesting to see the fix for this.

I had a similar issue with a stihl 025 older carb rebuilt it with a new meter and Same issue so I pulled the metering pulse valve side back apart and re adjusted the needle and it finally cleared up. Since i did port it and open the muffler it runs dead on now. Took me a few weeks as well to figure out how to work around the issue. You can do so and just richen the low jet up. Even though you already adjusted the meter to factory specs

I'm going to guess that the coil has a rev-limithing issue, and a new plug will help, for a short time, , , when the coil get hot, the rev-limiter fails. Try using an old coil that you know works for sure, even if it's not the one you want. (Is the coil on backwards), , , spark will still be generated (sometimes), but it's not picking up the polarity from the magnets correct (N and S poles are switched relative to the coils needs), or if it's a coil from a different model saw, maybe the poles on the other saw are not the same, or maybe there is a degree timing difference as compared to the flywheel that you are using. I wish you the best.. thanks for all of your videos.

Hey Tinman. I love that you show both the ups and downs to doing this stuff. Quick thought, is it possible that with the stock intake timing, the impulse signal is too strong at the diaphragm? Have you tried lowering the metering lever a tad to see if it clears up a bit? Either way, looking forward to seeing you get it dialed.

I know my saw sounds exactly the same as that until you put some heat to it... like make 4 or 5 cuts wide open and really lean into it and make it work and she should clean right up and you'll feel the powernband come on but sometimes it takes quite a few cuts to get it to come out of it, especially if your running a little rich or rich on the oil

Echo saws are tuned ragged edge on a balance btwn carb size and port sizes hence big high intake ports, muffler mods will help make power due to epa reasons that’s the route echo went to appease epa emissions, changing port timing throws everything out of whack when it’s on ragged edge of performance, I recommend getting a way bigger carb hole size wise, sounds like it’s pulling excess fuel due to higher than normal vacuum from the motor, just a guess, if you want to port echos port width by a bit but not much and don’t change timing

I don't think it's a fuel delivery problem. I think it's not getting full combustion because it not starting the combustion early enough. If it gets to the point to where you can't figure it out, try cutting the keyway out alil bit to the advance direction or slot the mounting hole in the coil to where you can advance the timing by moving the coil it's self backwards against the spin direction of the motor.
