upon reading my post I suspect some may sight the coil limiter. While it is possible (I don't actually even know if the saw has one) it seems unlikely because this is happening even when in a moderate cut and at seemingly lower rpm. It doesn't sound to be reving all that high before the machine-gunning starts happening. If it is the coil, I would suspect that it is kicking in when it shouldn't. This more or less starting happening out of the blue (as I suppose most problems do). I did pull kind of hard on the saw though when it got stuck once, and it may have gotten worse after that...

The 357Xp/359 doesn't have a coil limiter, They have the black coil.

The boot is rather fickle where the carb fastens on. The screw threads in the boot are plastic and will strip easily.

I would start looking at the boot. It must be tight on the cylinder and the carb attaching screws not stripped out.

There is a small amount of fuel storage in the carburetor and a leak in the fuel line typically causes a lean running condition or the saw just stops.

The only area of the carb itself to cause this would be in the metering valve (regulator diaphragm) area?

I forgot about this till Jim mentioned it. If you have the plastic clamp.

Service Bulletin for 357XP, 359, 353, 346XP
This service bulletin is not new. I thought that there might be some out there who were not aware of it so here it is. If your saw has a black plastic clamp around the intake right next to the cylinder it is applicable to it. If the clamp is of steel construction then you should be ok.

SB, 357 XP, 359, 353, 346 XP,
Partition wall and clamp for intake system,
2006-03

The existing intake system on 357XP, 359,353 and 346XP currently consists of an integrated plastic clamp in the partition wall. As the clamp is made of plastic, there is a risk of deformation. This results in impaired clamping force against the cylinder, which in turn can result in leakage in the intake system. To prevent this from occurring, we have now introduced a metal clamp and a new partition wall.

The new partition wall is made up of polyamide with 30 % fibre glass.
The new clamp is a hardened steel clamp. The new material and the design of the clamp reduce the risk of deformation and the subsequent risk of leakage.

Full replaceability prevails.
