Hi all;
Now that my sah-weet running '66 1600 has been sold (down-tha-road to
LA,
you'll probably see her on the list soon:-) I've started to think about my
neglected '69 2L.
I bought it in early December, and just haven't had time to monkey with it
yet. A couple-three things:
The temp sender isn't functioning right; I understand that this is
epidemic. What's the fix? I can't see an easy way to ground the sender
body....
I fear that the head gasket may be leaking; I'mma check the compression and
see what happens. Can the head gasket be retorqued? Is Stop Leak a good
idea, or given the cantankerous nature of the U20, should I just put a new
head gasket in? (oh yeah, what are the valve clearances supposed to be?)
(oh, and are there thicker head gaskets available to lower the CR? I hate
the thought of spending $1.75/gal for gas)
In further persuit of high-RPM fun, I'm going to take the distributor out
and inspect it; Here's the problem - It's VERY strong from idle, then it
pretty much runs out of steam at 4,500 or 5,000 RPM; The carbs are set up
well, AFAIK, but that's as far as I've taken it. The idle is kinda strange
- it will fall back to 1,300 or so really quick when the pedal is released,
and then SLOWLY settle back to a lumpy 900 or so. I'm suspicious that the
mechanical advance isn't performing properly; maybe a bit of crud gumming
up the works, or a broken spring, or something. Anyway, enough babbling -
my questions are:
1) do SU U20's crap out at 5,000 RPM as a matter of course
- if so, are there better needles available (reminds me of my
L28/SU 240Z before a needle change, FWIW)
2) should the distributor be worked over, change the advance curve, etc.?
- if so, is it something a competent shade-tree can do?
- if not, who does it, how long, and how much $$?
3) any pointers on how the dist is supposed to "feel" when out of the car?
TIA,
