Just picked up a 288 XP Lite and looking at the throttle lever, I believe it is worn out. Is this common on these saws? With the trigger pulled fully, you can move the butterfly an extra 1/8-3/16".
This leads to many of those having a lean seizure - if the operator uses a tach to "tune" it. They lean it out to get to the max rpm spec because the throttle is not fully open.

Throttle opened up but still no excitement. I checked the compression and we're around 100 psi. How it runs, I don't know but I think I'm on to a reason why it's down on power. For now it'll get set on the shelf whole until I have time to do a proper pull down and give it the going over it deserves.
While I'm in there should I get it ported or is the 288 enough animal in stock form?
I took my 288xp lite down for a rebuild, cold right after I put it together it blew 160psi no run time. As soon as I find my vacuum leak problem now i'll get a few tanks on it and get another reading. The little time I had it running I was shocked at how it reacted, totally brutal.
i may be wrong but it looks to me your 288 has one of those el cheapo chinese cylinders. i've never seen an original 288 top end with the decomp valve on that side of the cylinder but i have seen the chinese cylinders like that. could be wrong though. if i were you i'd go on the hunt to find an original cylinder for the rebuild if it is in fact chinese.
I believe all the 288XP Lites had the decomp valve. Later 'non-Lite' 288XP's did as well. In the IPL, you can see the decomp valve (and the boss on the cylinder where the valve goes) as well as a decomp blockoff plug for the cylinder and a plastic plug to cover the hole in the top cover when the decomp blockoff plug is used.
That de-comp is correct for that was as far as position goes. My original valve is light blue though. Would need to see more of the cylinder to say for sure, but at a glance it looks original.

I wish my 288xp had a decomp. Thing is a brute to pull. Sounds great though once running.
