Leaf Blower Dies When Throttle Over 50%

Hey Guys -
I have a gas powered leaf blower which I've been trying to fix, but can't figure it out. I found this forum so hoped posting my give an idea.
The blower is a backpack style and it's model is PB-265L. Here's a link to it's manual and below a picture of the actual blower:
I had it in storage for over a year and brought it out about a year ago. THe issue has been occuring since it was in storage. If it makes a difference, I weedeater was in the same storage and had the same issue so perhaps it was caused by environment? I ended up throwing the weedeater away after I couldn't fix it.
The throttle is controlled via a thumb level which must be "clicked" on to about 10% before you may start it. Once "clicked" into that position and rear switch moved to cold start, it starts easily - within 2-3 pulls. Once idling (seems normal and even), I switch the rear switch back to "normal" and strap it on.
Using the thumb switch, I can steadily take it up to ~50% and everything acts normally. Once I surpass ~50%, the engine starts to choke and eventually dies. If this starts to occur, I can pull it back down to under 50% and it usually recovers.
What I've Tried
- Replacing Gas
It takes a gas/oil mixture which I usually don't measure, but did in this case and no change. I even bought a pre-mixed can from Lowes and no change
- Air Filter
I removed the air filter and blew it out with compressed air (wasn't dirty anyways). Believe I also tried running while testing without filter - no change
- Replaced Fuel Filter
It has an in-tank fuel filter which attaches to the end of the feeding tube. I replaced it - no change
- Carborator Clean
I'm no expert, but know the basics. I took apart the small carb, cleaned it, and reassembled. No change
- Checked Hoses
I checked all hoses which are clear and seem to be good
So - any ideas as to what the issue may be or where to start? I'l be happy to provide more information or even upload a video if it helps. Thanks!
