Hi First turn them(H and L) clock wise until the end and then adjust.

high speed H=3/4 turn

lowspeed L=1 1/4 turn

idle speed T adjust accordingly

How do I unclog the carb on my push mower


Haha, nice one, but I am smarter than the average bear.

A PUSH mower does not have an engine, so therefore it does not have a carburetor.

I have a Ariens snowblower deluxe 30 which is a year old. Starts fine and will run. Unfortunatley it is running way to low. I have replace the gas with fresh gas ran it through completely


It is very possible the carbureator needs a cleaning. Moisture can corrode the inner parts of them if left all summer. I find that the fuel usually does not go bad over the summer. I always start my snowblower once a month over the summer and then have no problems when the snow flies again. There was a time when mine was losing power and quitting also. There is a screw on the bottom of my carbureator that needed adjusting. If you are lucky that may be all you need. By turning mine in and out a bit I found the spot where the gas was correct and it worked fine again.

Talon electric chainsaw has no power, changed the fuse etc...any ideas??


talon chain saws have two control switches before they will start. One is the trigger that you pull and the other is a button or lever that has to be held in at the same time. These two controls mean that you have to have both hands clear of the chain before it works.

My weed eater will not run with the choke setting wide open.


You may have a pinhole or crack in the small hose that runs from the fuel tank to the carburetor. If equipped with a primer it may also have a small crack or pinhole. Either case may cause the carb to suck air instead of gasoline. Other possible reasons are a plugged muffler causing too much back pressure or a partially clogged fuel filter. (The fuel filter on many weed whackers are located inside the fuel tank at the end of the fuel line.)

Pentair whisperflo 3/4 hp left running over an hour with no water


Sorry to have to tell you but you are going to have to either have your pump rebuilt or replaced. Sounds like you baked the plastic impeller and maybe did even more damage. These pumps require water in order to keep cool.
