Thanks for the help on Spitfire 1500 rocker clearences. I went with Mr.
Wanda's suggestion and set them all at 0.012. I've checked compression,
cleaned and re-gapped the plugs, and assured that the vaccuum mechanisms are
working.
The car has been running very rich. I found that the jet needle is fully up
against the stop of the air valve. This would seem to be the running rich
culprit. However, I noticed that there seems to be no mechnism to hold the
needle jet in position. That is, using the Allen wrench to make
counter-clockwise turns of the jet needle to lean the mixture, there seems
to be little interference to get the needle to hold a position. Also, I
haven't found an O-ring and the damper was devoid of oil.
I have the Haynes Stromberg manual and the parts I'm finding seem to jive
with the exploded diagram. I've checked for a torn diaphram and the car now
has a manual choke. I haven't checked float level yet.
New Question ('79 Spitfire):
What can be done to assure the needle jet will hold it's position once a
proper mixture setting is determined? I don't think the grub screw on the
side of the air valve helps here. It just prevents the jet from falling out.
The threads in the adjustment seems to be pretty loose. I can't find any
locking mechanism for needle jet position.
I am inclined to use a dab of blue LocTite on the threads prior to trying to
tune the mixture. Is that a good idea?
One other thing: do you have to remove the entire carb and flip it over to
check the float level? That's the opinion I got from the manual. Seems undue
punishment to me.
Thanks for your help, again, and please send responses to me so I might
avoid waiting for the digest.
