honda hrm21 question

(bertsmobile1 ).

Thx for reply. It does seem to me float issue but when I take bowl off it’s approx 2/3 full. So seems should be where it needs to b. Jets oblong May be good.
What caused it all was it was running little weak then I ran it out of gas trying to finish up last bit of yard. I thought running out of gas may have god something in carb, took apart couple times before seeing o-ring on jet was bad. I ran out of thoughts with carb why I wanted to check key.

But when you add the float to the bowl the fuel level will rise.
The height of the fuel in the bowl makes a massive difference to the volume of fuel that a flow of air will draw into the engine.
I like to take the bowl off & work it manually while blowing into the fuel line (Yummy petrol lips ) .
The valve must cut off the air before the float touches the carb body.
Fuel pumps put out around 7-10psi so you can also pull the fuel line off at the pump and see if it will hold against 10 psi
But I like to see exactly where the float is when it shuts off the valve.

Over time the tang that pushes on the needle can both bend & wear away and a very small dent in the tang equates to a lot of float movement.
