35hp stump grinder bogs down at full throttle position and blade is under load

SOURCE: homelite 26bp backpack won't run up to full throttle

I have let my leaf blower run and warm up before throttling up and still it bogs down and shuts down. There is no air cleaner to clean should I just blow out the carb. and fuel lines?
It runs and idles just no high speed to blow.

Have you tried cleaning the carb?

Testimonial: "Thanks for the suggestion, that sounds like what it may be. "

I took the carb off (easy- two screws), rebuilt and cleaned it, removed the black "H" & "L" needle jet screws (with no screwdriver slots) with a tiny pair of needle nose pliars, 1/8 turn at a time. They are very tight. Then I cut the slots with a fine hacksaw blade and re-installed them. BEFORE you begin, MARK where the "pointer" notch is on each screw so that you know where to reset them and count the turns coming out. Also, cutting the slot 90 degrees off of the pointer mark helps.
An option would be to hold the carb body in a vise and cut the screw slots thru the aluminum guard. Be very gentle, the screws are soft steel. If I had to do it again, that's what I'd do.
Get it running and adjust the "L" at idle until it runs smooth as rich (open) as it can. Then hold the throttle wide open and open the "H" (high speed needle jet) until it runs smooth, as rich as possible. This can be a CHORE.
Remember, richer (more fuel) is better than too lean. Too lean means less lubrication and running much hotter. 80% of the cooling in gasoline engines is from the evaporative effect of the charge coming into the engine. That's why carbs ice-up well above freezing. Ask any pilot.

Sounds to me as tho it might need a carburetor adjustment, providing there is an adjustment screw on the carb. Sounds like the engine is running a bit lean. Did this problem occur right after the carb cleaning, or was it there in advance? Is there a fuel filter that might be clogged?

Probably need to adjust the high and low speed settings on the carburetor.
See your owners manual for location and adjustment procedures.
