The bolts are tight - I've removed the carb several times, but I'll

Tecumseh engine has two adjustable needle valves. I adjusted these
both to 1-1/2 turns from fully closed. Is that right.

Thanks for the tip.

At the garage sale, I bought a B&D electric edger for $15 and the
owner threw in the gas one for another ten.

1-1/2 turns is the starting point and should run pretty good there.

First, are you sure both screws are for needle valves? Could one be
for the idle? Usually there is only one needle to adjust.

Second, if the carb sits on top of the tank, be sure the screen
(filter) at the bottom of the pick-up tube is not blocked. Also check
to see that water or debris isn't laying on the bottom of the tank.
Cleaning just the carb and not cleaning the entire fuel system isn't
doing much good.


I got a freebie chipper with a tecumseh engine that would not run right. I
finally figuered out that someone had reversed the needles in the jets. I
swapped the low speed and high speed needles and everything worked great.

The 1 1/2 turn adjustment is a starting point only.
