Thanks for all your help Gents, I went through the carb again last night and I had the Gaskets backwards as well.

When it warms up some I will go out and try it :)

Having the gaskets/diaphragms installation reversed is possibly one of the most common problems with a recently disassembled carburetor.
We should share what we know... someone may learn...
That knowledge can live after us... and that "Pays It Forward".

It has happened to us all at one time or another

For several years I could not remember which way was which?

Finally I studied how the pumped/regulator carburetor actually works and remembered how the gaskets went after that.

The Walbro, Zama, & and Tillotson carbs are all the same in this respect.

Still will not start..
Suspected spark plug, pulled a known good plug and put the suspect plug in another saw and it ran fine.
So now...
Pull oiler and check the seal?
Pull Carb again and check the lever on the bottom, not sure what is it called?

I need a comp tester and a spark checker.

This is harder than my 288 was

WTF!

Probably still flooded.  Make sure the choke is OPEN.  Set the throttle lock.  Flip the kill switch to stop, pull the plug, turn the saw upside-down (yes really) and pull the rope a buncha times.  Betcha fuel blasts out.  Flip it right side up and pull a bunch more times.  Wipe things off, replace the plug (and connect the plug wire of course), flip the switch to run, check again that the choke is fully open (forward), check that the throttle lock is still set, and then pull.  Should fire after a few pulls, clear out, and run.

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.

Very true.  Also letting it sit for a while with the plug out helps, as does blowing the fuel out of the plug with compressed air.  I have burned the fuel out of the 'business end' of a plug with a lighter before..............but that's probably not the smartest idea. 

Not as dumb as when I degreased a muffler that I'd been grindin' on with brake cleaner (prior to painting it with BBQ paint)................................and then got the bright idea to burn the residual BC off when it wasn't evaporating fast enough for my impatience.  WOOF!!!!!  I lost some hair from my arm and the back of my hand because of that dumb move........

So I did all that you said and still no go.
I pulled the cylinder off and still had gas in the crank case.

I then decided to look in the carb again...

The "fuel inlet lever", if I push the end of it down into the carb, it will not go all the way down maybe half way.
I have no idea what that means, but I assume that it is not good.

So now lets go to plan B.
I have another Husky carb, so what do you think of me pulling off my Carb kit that is on the "broken" carb and putting it on my spare carb.
Sounds good to me, but...

thanks for any help and thoughts.

:)
