Does it look like it was dropped the on the cylinder without the cover being on.

I've seen this break before. and the rear tab is very common and not near as important.
I get the feeling it has something to do with the fit of the top cover. and vibration.

I have never welded a fin back onto a cylinder before but if your willing to take a chance I can give it a go.

What carb is on a Titan 57?  Funny..................guys use Titan 57 pistons in some other saws.  I hate those damn Titan saws (was a sin to reuse the grand old Titan chainsaw name on that line of .........), but I guess they have their usefulness afterall....8)
-Aaron

For older saws:
Tune the H side so that it 4-strokes (burbles) at WOT unloaded and just cleans up when under load.
When you lift cutting load, the saw should immediately revert to 4-stroking.  Fine tune the transition point for the wood you're cutting.

one of the things I don't understand is the feeling that the fuel/oil lines are a difficult thing to do on the titan 50/57 model. there's more than enough room for the lines and your hands to fit. they come apart easily and it's pretty self explanatory where they go. quite honestly, I can have a titan 57 done way faster than most can have the lines done on any of the 'homeowner' models either stihl or Husqvarna are putting out. they're not even close to being bad to do.
mind you. I've been doing then since the release of them ;) ;D
the carb off the titan is a walbro hda, just larger breathing space.
you need to drill the small pulse passage and change some small bits over. but it's pretty straight forward.
i'll be doing a small how to on it when I get around to pulling the 400 down. :)
never have done this on a 4000, but on the 3400 and 3700 with the intake block smoothed and matched, it does wake them up nicely.

I may swap a Walbro SDC or Tillotson HS onto my PP375 sometime soon.  Got a bunch of different variants of both to pick from.   I'm not a fan of HDB (or HDA) carbs, although they do work well..................when they work well.

Aaron I am not up to speed on the different model carbs.   The ones you like what saws do they normally come on and are they larger in venturi size.
