An odd screw driver for Tanaka 33ED
By: chy_farm Date: April 13, 2017, 10:02 pm
---------------------------------------------------------
This is a short report to make an odd screw driver for my little
Tanaka 33ED, which model name here is Tanaka PCS-33EDTP, a top
handle trimming saw for light use. (see the first pic.)
When you tear her down to see her carburetor, you will find a
couple of "impressive" threads where conventional H and L screws
sit. (see the 2nd pic)
These heads do not have cross cuttings for the driver, having
only flat heads. Instead you can find cutting on each of their
side wall.
In a purpose to tinker these, we have to make a small and very
simple Odd Screw Driver, one like this. (see the 3rd pic)
This driver fits to these odd screws on the one side, and fits
to the throttle adjuster on the other side. (see the 4th and 5th
pic)
The material you need for this new driver is;
a brass pipe, with 6mm outer diameter, 5mm inner diameter.
Cut the pipe 2 or 3 inches, grind the both ends, and softly give
it a bend on the circumference of one end so that it fits to the
cutting of these special screws.
You'd better give the other end some taps to get it flattened
for throttle adjusting purpose.

They make the proper driver for that screw. It's called a D
driver. many brands of 2 stroke use it and multiple other
variations. You can get them off ebay or as you did, make your
own that do the same job.

Yep I seen that and knew I had the single D already too.
Nice job on making the tool though. I used to just cut slots in
them. I just gave in and bought all the little carb tools
later.
