Here's a 550XP that ported this afternoon. This one is headed to high elevation in Colorado, so needed everything we could give it.

Sawing for Sanity
Damn Brad,
That looks like it'll haul the mail... What all did you do to it? The throttle response is fantastic and it's definitely holding rpm in the cut. Out of question, what pitch cutters are you using and if .325, how much of a loss (if any) might there be running 3/8"?

Is it just me or is that chain a bit tight? If you look closely at the video you can see what looks like smoke coming off the bar top at just above mid cut. It could be water vapor from the log maybe but the chain has no slack in it after the first few seconds of the video and at times appears to stop rather abruptly right after the first cut and again when you stop and restart it. sounds healthy though.
Oh such fond memories of the days spent at camp, with more time to do things!
You should have painted it to get rid of that silver, ah never mind it will disappear on its own soon enough.

It's .325 chisel chain. I've never run 3/8 chain on one, although others do and say it runs fine.
Here's the trick to the throttle response. What we're looking at is the brass plug just above the left mounting bolt hole. The earlier 550s do not have this plug, which must be removed. Removing it is as simple as drilling a hole in it and popping it out. I found this adjustment needle on the first 550 I did. Mitch can explain it's function much better than I can, but it has the same affect as a L needle on a typical carb. This one here was seated. I backed it out 1/4 turn. The needle has an o-ring on it, so stays where you put it.
If you have a 550 with hesitation off idle, this is probably what you need to do.

16". It's actually heavier than the stock bar that comes with these saws.
good to see you back.
Sweet! As always awesome photo work.

Brad, a trick for getting those plugs out is to find the right size plug or bottoming tap and thread it in there and pull. Not my idea but it works well. Maybe you already do this. Just thought I'd mention it.
Is this the new rep thread....??
Bad rep?
You seem tense.
Wanna talk about it....??
