So I acquired a really nice Echo CS330T and was breaking it down to clean and go over. Removed the carb, pull start and top little cover. This piece below came out upon disassembly and I am miffed as to where it goes? I'm assuming on the linkage for the carb some where? I also open the top handle where the linkage connects there also.
I do not see this on am IPL anywhere

Also while I have you guys looking, would you guys run the pictured bar below? Or is there a way to straighten her out? Or just buy a new one?

Is it a limiter for one of the carb screws?
I'll see if I still have my limiters that were on my 330t--don't remember them looking like that but it's been 2 or 3 months!!!

I love my 330t, it has 14" bar--thought about a 12", but don't have an extra. Not cut with it a lot, but has quickly become one of my favorite saws!

No, not a limiter, those were red and I removed them after this piece reared it's ugly head.
I'm thinking it goes on the linkage into either the throttle trigger or in the carb connections
 
On the same saw, the Carb is a WT 739. Just rebuilt she carb with a k20 wat kit, but still having a hard to start issue. Saw on the Bay a person selling a replacement wt 1015-1 for the 739??
 
I can't get this thing to fire up. Compression feel sgood and spark is good. What's a good starting point on the needles no matter what I do she sputters only

Update: actually compression may not be good

Ok got her started and running like a champ!!!
This is what I did: After getting the 95 psi compression, I squirted some oil in the cylinder and it pretty much was hydro locked from too much oil, so I pulled the compression hose and cleared the cylinder a bit and replaced the hose and instantly got

Replaced the plug and she fired right up and ran like a new saw.
So my question is: is there a read valve or anything that the oil freed up to give me compression back?
Stuck ring???
 
Man, no replies seams like all the threads died this week?
 
It was sitting quite a while so I suppose that could be a possibility, I never experienced that before. I put the oil in there to see if it am definitely a difference in compression to check the rings and it brought it right back to life. It IMMEDIATELY fired up afterwards.
