Dual port muffler on a 660

[armchairarborist]

iv had 66,s for yrs & never had the need to tinker with them ,as they have ample power ,& you should never rev a saw on a hard serface like that as it can crack the casing!!!!!

 

he's right rob, you get less for them on ebay when the bottoms worn off:biggrin:

It's on gravel, there is a patch of concrete next to it but I chose the softer ground.

 

a bit of noise pollution never hurt anyone:thumbup:, but i had a vicar screaming at me (proper mad, red face and twitching) when i had been ringing up logs for a few hours in the next garden with same mod on ms460:lol:

 

I'll have a race with you on Wednesday! I'll have a similar bar too so we shall see who is th victor

I wouldn't say I'm revving it's knackers off there. It's 6 months old and is run in well. i rev it less hard after a cold start, then ease the power on and off.

 

I barely even hit full throttle, revving it's knackers off isn't good for any engine. Most people know that!

 

What does revving it like that have to do with it being sat on the yard?

Rob, do you have a bigger bar for it?

 

I hope you didnt mod it just for pulling that chain length did you?

[RobRainford]

No, I use the 20" because then I get more use, but I have got a 36 for it and a 25 on the way.
