SOURCE: At full throttle and choke off, blower slows down

Fuel starvation - 'lean fuel' condition
Basic things to check:
1) spark plug
2) spark arrestor in muffler
3) fuel lines and tank filter
4) turn adjustment needles out (counterclockwise) 1/4 to 1/2 turn
Chain Saws:
5) check impulse tube and intake boot for cracks or leaks
*if all of the above are OK and/or do not improve performance then:
Remove Carburetor
6) replace gaskets/diaphragms
a) use a spray carb cleaner to clean jets, holes, and body of carb
b) fuel pump diaphragm goes against the carb body,
then the gasket towards the outside
c) metering gasket goes against the carb body,
and the diaphragm goes towards the outside

SOURCE: mighty lite 26b leaf blower will not go full

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.

SOURCE: 2-cycle blower starts up but wont run full power rpm

Have you tried choking it about half way and see if that helps? Does it do the same after it is warmed up?

SOURCE: homelite backpack blower ut08083 or ut08111 engine

could be two things from description the first is the carb needs a clean out and the second is the metal flap behind the engine cowl has corroded awy reducing its size ,most likely is the carb though as its one of them funny ones designed to work at any angle like a chain saw.So firstly try cleaning the carb out and see what happens ,these always get choked up when not used regular as when put away teh carb isnt drained so petrol evaporates leaving a fine white coating which can and does block the jets up

SOURCE: Blower not running at high

Try removing the muffler and look inside of the exaust port, you should be able to see the piston in the full opening of the port. If you can, try starting and running at wide open throttle. If it runs fine( a bit loud, so wear hering protection), then you have a plugged or partialy blocked muffler or spark arestor. Sometimes rich mixture can cause excessive carbon build up.

Hope this was helpfull.

While ac on rpm fluctuates


You need to clean the engine throttle body and the automatic idle speed control motor, they are likely full of cylinder backwash deposits and this causes the problem. Use throttle body spray celaner form the auto parts store and after cleaning disconnect the battery for 5 minutes to reset the system.

It is much more likely you are low on coolant or you have an air bubble trapped in the cooling system. You should bleed the cooling system to get any trapped air out and make sure it is full of coolant.

How do I adjust needle valves on a 25cc Homelite UT08111A Backpack leaf blower?


Set the lowend & highend needles to about 1 3/4 to 2 turns each. Choke the carb or prime it, until the carb is wet. Fire up the engine and let it warm up. Let's set the topend first since it's the easier of the two. Go to full throttle. Adjust the topend needle for peak RPM. Leave it wide open for about a minute to see if it changes any. Should the engine go lean, open the lowend needle slightly, if this dosen't work... you will have to adjust the needle valve inside the carb.( I will explain this later) If the topend runs OK, then slowly pull the throttle down until the engine begins to "four cycle" hold the throttle there. Adjust the lowend needle until the "four cycling" barely stops. Now lower the throttle more until it "four cycles" again, and adjust the lowend again. Keep doing this until you reach full idle. Now, from full idle begin to throttle up until the engine starts to bog or hesitate. Open up the lowend needle just enough to eliminate the bog or hesitation.

1990 Honda Prelude 2.0 si F.I. Idle Fluctuation


This problem is a little bit hard to coz you need to check the following throttle body, fast idle valve & the IACV valve. First the throttle body it must fully closed during idle and the TP sensor voltage must be 0.5 volt. The fast idle valve is wax type there is a 2 small hose pass below of this valve, if the coolant water is not circulating the valve will not closed. You can check it by touching the lower portion of this valve after 1 min. Regarding the IACV you can check if this is the fault by removing the hose connecting the throttle body and air filter. there is 2 small hole near the opening of the throttle body, while the engine is running at idle close one by one and see which one cause this problem.I hope this will give help to your problem.
