Idle problem on C15 261 CU IN

[TCLARK]

Hi Phil and Bob
Phil you were right just a small hole to suck vaccuum thru for the
distributor. I would guess for dampening also.

Bob I just got the spacer made ,it took about an hour but visiting neighbors
for a piece of 5/8 flat took half the day.
I put it all together and voila about 20 inces at 475 rpm idle. I'm
so happy, this engine purrs like never before.

Now I have to hook up the wipers does anyone know where to get the proper Blades?? I have one new nos wiper arm I got at a swap meet (even orig. OD) and one not
so good but usable. How does the blade attach to the arm?

Cheers and thanks for the great advice!
Terry
