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!

Check the plug boot. The spring inside can come loose. My saw is having the same issues. It will make this particular saw run all over the place. When its right its great. 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.

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.

I had Plugs on Honda GCV engines that died after a Minute after Coldstart. Restart and die again. Had a Dolmar 5000 that ran perfectly but wont hotstart. Some Plugs have Spark but wont start. You can get crazy, so first put in fresh Gas and a second test Plug. Then try the rest. Kind Regards from Germany

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'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.

Murphys law, the weirdest shit happens. Dad had a 4.0 jeep die and wouldn't start. Everything checked out but no spark. Changed every sensor, plugs wires etc, still nothing. He figured it jumped timing, so changed timing chain, camshaft etc. Still nothing. I was in high school and new nothing about mechanics. But he ask me to help tell him when it was TDC as he bumped the key. I noticed the distributor rotor wasn't turning. I said "isn't this pointy thing supposed to turn?" He about $hit, Lol Turned out the distributor rotor gear sheared teeth and was stuck at the #1 position. So running through his setup, he would turn the motor by hand to #1 TDC, looking down at timing marks and feeling for compression on #1. Then hed look up at the distributor, to check it was in correct position. He never noticed it wasn't turning! Took another set of eyes to see that the rotor wasn't turning, it just broke through $hit luck pointing right at #1. Few years later, on another vehicle, I had the same thing happen to me. Took me a while, but I remembered ole Murphy, so I figured it out much sooner than he did cause I learned from his mistake. I was lucky it was 70 degrees out and figured it out in hours, when it was 20 and days for him, and he's still a much better mechanic than me. 🤪 TLDR: Only two times I ever sheared distributor teeth, and both times it was pointed right at #1 TDC, the little things always bite the hardest!

But maybe it needs a different carb now. Would be interesting to see the fix for this.
