Working on a RedMax HBX2601 leaf blower. Starts and idles great. Will not reach max rpm without choking it intermittently. Runs better upside down for a while. I have:
-replaced tank lines n filter
-replaced carb with new
-gaskets between carb n plastic isolator
are seating

Suggestions?.................................................This thing is about to get recycled...what am I missing?

It is possible you have gasket or seal problem with the crankcase. This is where a pressure/Vacuum tests are used to find the problem area.

It is to be note the entire crankcase is part of the engine intake system in two cycle engine.

Well I got the gaskets covered but I honestly did not consider a crankshaft seal leak. Thanks again, I'll test the crankcase for a leak elsewhere....thanks you a bunch!!

And if the carb was a cheapie of AmmoZone or Evipay no reason to believe it was correctly jetted or even is good

True that.................................I put the old carb back on with no change. Crankcase leak is making sense.
