All I know is when I order gasket kit it comes with 3-4 cylinder gaskets. 

I just snug clamps tight.

I just tighten cylinder bolts and check retighten after use.

Do I need a ring compressor to get the piston back in the cylinder?  Is there an easy way to remover the carbon on the top of the piston or should I chisel it off or just leave it alone?

I leave the carbon alone.

Generally the rings will go up in the piston.

I have used a wire tie around the ring(s) and cut them away after the piston goes up in the cylinder.

I am going to start a new thread since this is no longer a carb issue.

My first 3750 had a **** base gasket. Was sold to me online on bay as runs perfect. 

That saw in a way is what has lead to this site being put together.   Dolmar echo poulan dealer gave me estimate of $200+ to fix $170 saw.  I took my parts back and started reading online on how to repair myself.

Replaced the base gasket and got the saw put back together.  Runs like it new!  Thanks!

Great to hear.
-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.

What saw did the HDA77 come from?  Did Mitch have to modify the carb or change parts for it to work on the 3450?
