911 smells like a boat!
It's been drizzling all day and I started the 1980 911 up today and it sounded like it's about to backfire, it also smells rich like a boat. A couple days ago I put in some CRC to clean up the CO emissions and clean the carbon off the engine but it hasn't affected the car for the last two days. Is that the issue? Also, why does the engine sound like it's about to sputter out when you take the cap off to check the oil?
Any help would be great. Thanks

Oh, I ordered a fuel filter cause I thought the stuff I put in the engine might have stirred up the crap in it. Do you all think this is the right idea or is it something else?

Can't say why your SC "smells like a boat", but the change in idle speed you notice when taking off the oil fill cap, is normal.
When you take off the cap, you are affecting the stability of the motor's vacuum. Actually, this is one way to test for other leaks in the vacuum lines. If you take the cap off and the idle does not change, you may have a bad cap gasket and/or other vacuum leaks.

Seth,
FYI, you have two fuel filters in the 911SC, one in gas tank, accessible from the bottom, and the one normally changed in the engine compartment. When I changed my gas tank filter on my 81SC last year, it was pretty clean.

Anything special I should know about changing the gas filter? I think all my problem was was the ignition coil was loose. Why are the spark plug caps all loose? Are they supposed to be like that? They dont seem to be 'tightenable'

Seth,
Take a look at the Rennlist Tech site at tech.rennlist.com under 911 engines for an article on changing the gas tank filter (CIS fuel system tuneup).
Changing the engine gas filter involves undoing the nuts on each end of the filter (have a cloth below it to catch gas) and replacing it. Note the arrow on gas flow on the one you take out and do the same on the one you put in.
The spark plugs wires should be tightly in the distributor cover, and where they attach to the spark plugs, you should feel the cable end snap onto the tip of the spark plug. There may be some wiggle in the spark plug connector, but it should not be loose. If you're not getting the snap when it hooks onto the spark plug, I'd compress the metal piece in the spark plug cable that snaps onto the spark plug a little bit. Too much and it won't attach to the spark plug.
