Cranks. Runs fine at idle and up to maybe 50% power. Throttle more and it just bogs down. Echo Backpack PB-580T.
I've changed gas. Ran some Startron through it. Changed plug. Exposed carb and sprayed with carb cleaner. No change. Haven't taken carb off yet. I'm not small engine proficient.
Ideas?

Ahhh. I recall vaguely something else a long time ago with spark arrestor issue. Thanks for the tip. Will try that next.

Swapping out the carb for a cheap new one from China is usually very easy. Lots of videos to show you how if the spark arrestor isn't dirty. That will get you a new carb/fuel filter/new gas lines/spark plug etc in those kits for less than $20.00 bucks on Amazon.

$100 says it’s the spark arrestor
Take it out and spray it with brake cleaner or just throw it in the trash.

If not exhaust stopped up. Adjust carb . Many videos on utube for that . Basic adjustment is screw both high a low screws all way in a back 1an 1/2 turn an go from there . Low screw mostly adjust throttle response . High screw for top end rpm.

High speed circuit in the carb is blocked. Hand held small engine carbs are very difficult to clean and get right. This is coming from a professional mechanic. The juice just isn’t worth the squeeze. Replace the carb and it’ll fix it. BUY AN OEM CARB, not chicom. Looks like they’re $45 for that echo.
I'll check that after cleaning arrestor

I'll check that after cleaning arrestor Don’t clean it chunk it. They’re useless. All my small equipments are removed. Including my sxs. It’s a useless part
