Ah cheers. So what do you reckon - it wont last long before just conking out?

The usual weak points are piston to cylinder fit, circlips and brittle piston rings, it will be one of these if it fails!

Thanks spud. I'll just see how it goes i guess. :-)

Hi if it's any help as regards your hole, I just looked at an old tecomec pot (off 026) and it's the same. Think the hole is to allow plug spanner to fit over plug, from memory the Stihl ones were close fitting.

 

Don't wanna divert off topic toouch but can anyone point me in the direction of a good quality make pot n piston for 346xpg ( I just mixed 20lt of fuel n dint shake the can, my son decanted into combi filled up n saw died after 20 mins) I'm not popular!

Cheers John

Good quality means OEM if the cylinder needs to be changed. Often it is possible to save it, and just change the piston though.

If that is the case, a Meteor piston will be fine.

Check it was the un mixed fuel and not an air leak from somewhere or you will be fixing it again ....

Hi stubby, I will check but I'm 99% sure it was my error as saw had had a couple of tanks of previous mix through it that morning ( we've had trouble with 346 pot bolts comin loose in the past ) : )
