Did you remove the limiters on the carb needles?
This should help you.
Stock saws can run limiter full rich or full lean. The limiter keeps the home owner from destroying their saw, while allowing them to dial in the performance due to elevation, temp, humidity, etc. In modifying the saw and removing the limiter, you better know what you are doing.
That 9,600 is rpm under load, in the cut. Put a 346 ignition module on mine, but if you are leaving stock, no need for it. Like to hear mine start to 4 stroke, when getting out of cut. Put an 8 pin on it and enjoy.Got some fresh fuel today and mixed at 32:1. Took the saw out to cut some cookies and try and get this thing dialed in. I have been reading quite a bit on the limited coils and how to be careful that you don't go to lean by mistaking the saw 4 stroking for the rev limiter. I had read some things that said start out real rich so you will see the difference. I started out real rich and started leaning it out. I think I was being way to cautious. My manual says the limiter is set at 13,000RPMs. When I had it real rich I could hear it burble real bad. As I got leaner and the RPMs went up I got to where I couldn't tell if if the burble I was hearing was a good burble as in 4 stroking or a bad burble as in the rev limiter. I was using a 8x8 to cut cookies. The last few cookies I cut at WOT, I shut it down and pulled the plug, seemed a little damp but also gray in color. At that point I was confused because wet should be to rich but gray would be to lean? It was getting dark so I cleaned the saw up and put it away.
I am not experienced tuning so I think I am gonna order a tach. Then if it is cutting out at 11,000 RPMs I know its 4 stroking and not the limiter. What should I be aiming to tune this thing to anyways? The husky site says the max power RPM is 9,600. But seems if they didn't want you going over that, that they would set the limiter at that RPM. I was just super scared of going to lean and ruining my brand new engine. Can't risk that.
There's a Husky Spec Sticky for your rpm question.
You will not go wrong with a 390 xp, very good power and fairly smoothly running for a near 90 cc saw, it will have all the power you need, if you have the money and this is saw you think you want purchase one. I would suggest purchasing a 24” bar as well, 28s get heavy and cumbersome really quick, take care and be safe out there, welcome to the site.
