What's the trick for installing the vacuum screws ?

[Guest]

Hi,

will need to re-do the vacuum synch as I cleaned the carbs...bike died at 6,000 rpm (full throttle). I have the Morgan Carbtune but keep on struggling at installing the screws in the carb inlets after the vacuum synch is done.

Is there a trick ? I keep on burning my fingers, dropping the small screws
that then dissappear under the starter lid or between the cool fins...

not encouraging...

any help appreciated...

use a long screwdriver, put a blob of grease on the tip so the screw sticks to it while you line it up with the hole.

Wait 15-20 minutes for the engine to cool down?

I have an Xcelite metric driver set that I use exclusively for carb screws.
Looking at the picture below, starting at the right, I use the handle, the extension and the second bit, which is 4mm.


It can be a bit difficult at times, because the bits are ball-end, but, like Agemax says, use a dab of grease on the end, it holds the screw just fine.
I have thought about using a straight-end bit, but the driver has to come in at an angle, which would cross-thread the screw.

The #2 carb is probably the worst one, because you are working around the clutch cable. I put a shop rag over the starter so that when I inevitably drop a screw, it lands on the rag instead of falling into that tight crack between the starter and the cylinders. MUCH easier to pull out the rag and retrieve the screw.

^^^^those are some excellent 'old man tricks'....no offense steve. I like the rag idea.

Like was said..use a LONG allen wrench and out the two inner ones in first. The outer ones wont be that difficult.

Steve..i just lay my pencil magnet on the starter to get the dropped screw and washer back. The rag will also be a good heat shield from the hotter surfaces though.

Absolutely no offense taken.

Sometimes, "old men" seem to have experienced just a wee bit more.

I have heard it said that good judgement comes from experience.
Unfortunately, a lot of experience comes from bad judgement.

Just wondering what kind of pencil magnet you have that will pick up the copper (or brass) washer?

If the washer is still on the screw, you might have a chance. If not, you will need a bent point on a scribe (my favorite tool) to try to hook that sucker out of there.
