One of the most annoying
and difficult things to clean or replace on the carbs everyone loves to
hate are the accelerator pump valves. Although it's an ingeniously simple
and effective design, it was not designed to withstand the abuse many idiots
put them through by leaving gas in the carbs to rot and permanently clog
the valves. You can tell if the valves are not working by putting your
mouth over the inlet (arow) and pushing air through it. If no air will
pass or will but when you suck on it like a straw air can flow both ways
it's not going to do much for you when you yank the throtte. If you want
it to work it's time to clean up the tiny bits inside. Here's the list
of "stuff" to git er done...
1. PIn vise or other small bit
chuck, here I am using an older X-acto knife with the crossed slots.
2. Very small wood/plastic
screw, and I do mean small. This I stripped from a dead alarm clock.
3. A phillips head screwdriver
that fits the screw well, one with a magnetic tip makes the job a lot easier.
4. Drill bit aobut 1.25mm
or so, any larger and you make the walls of the nylon retainer too thin
to re-use, any smaller and the threads on the screw might not grab and
hold.
5. Not picutred but used
is some WD-40, a small center punch, Needlenose with tiny tip, small standard
precision screwdriver, air pistol with small nozzle, and small wad of fine
steel wool along with a clean rag.
Before we get started,
no comments about my knarly greasy hands! I turn my own wrenches an it's
just something that happens when I do.
