Carb Adjustment Homelite 33 CC Chain Saw
I have owned a Homelite 14" chain saw for a number of years, the first one purchased in 1993. That first one came with a manual that gave guidance on adjusting the carb, including idle and hight speed jets.
My newer one, purchased in about 2005, has been running poorly, lack of power, in fact it is hard to get it to run at full throttle. The manual for this newer saw notes the need to adjust the high speed jet as a possible fix, however, there is no information on where that is, and advises that the saw needs to be taken to the dealer for adjustment of the high speed jet.
Looking at the saw I see two openings in the engine cover, just behind the pull rope handle. One marked "T" and an elongated hole marked "L" and "H". The "T" is clearly the idle speed or "Throttle" set. The other two are rather recessed and hard to see, but with good sunlight or flashlight one can see that inside the elongated hole are two small "nut" heads, perhaps 3/16" or a bit smaller and not much clearance around them, i.e., need a thin-wall socket. I figured this was just another attempt to thwart user adjustments. I stuck a small screw driver in and tried to rotate the "H" a bit, and succeeded ... the saw runs much, much better. The reason for this story? Well, is it possible to get a thin-wall socket or thin-wall nut driver for adjusting these adjustments? What is the size, my 3/16" nut driver looked about right, but the head was too thick to get in onto the adjustment nut.
In the good old days, the owner's manual would tell what tool was needed. Better, there adjustment "screws" would have a "screw" head.
