Can someone tell me what this little ROUND RED button is for, on the Pro Mac 700?
Thank you in advance!

Thank you. I should've asked before I dislocated my shoulder.

Just remember, engineers are loathe to add unnecessary features to a machine.
Lol. I like to think I’m manly enough to ‘not’ need them, but as the years go by I tell myself, hey, I’m merely doing the responsible thing by removing unnecessary additional stresses on the starter mechanism. Mainly my shoulder and back.
I have a Husqvarna 372XP that is hard to pull whether I use the de-comp or not, the compression is the same. I unscrewed the valve and took it out and it didn't help.
Strange. Hole plugged?
Prolly carboned up.
Yeah, I tried poking around in it but it didn't help. I've got most of it apart right now so I'll probably remove the cylinder and see if I can unstop it. It's carboned up pretty bad. Might just buy some Caber rings and install them before I put it together. Hope that's all it needs.

“Manly enough to pull it” is one thing but if it’s easier on the starter assembly then that’s all the reason to use it IMO. Especially on the older saws

I was trying to suggest that myself in my own way. Sorry if that was lost in translation. Lol
All the ‘manly’ stuff come homes to roost eventually.
Trust me.
Trust me.
The person that owned the saw before me said it was stuck. It wasn't but it sure was hard to pull. I also have a 362XP that's got great compression but is easy to pull with the de-comp working.

Weird the Pro Mac 800 that is sitting near my desk doesn't have a decomp. Is the 700 bigger?
The 800 isn't too hard to pull.

IIRC they have a Q-port I believe it’s called on the top of the exhaust port. Supposed to act as a decomp at starting speeds.
How many of the macs had the decompresser in that location? I had a mac with it there back in the late 60's but I do not remember the model.
Sadly most of the Macs didn't have it...at least not many that I've had.
Correct recall. Ron
