[DMCForum] Re: CO2 E & F Series, Etc.



Bad news Martin: I'm looking at a page from Volvo literature right
now. CO2 is 2.0% on B27E and B28E, including Sweden & Australia. Is
1.7% on B27F through 1976, dropping to 1.0% thereafter and B28F. I'll
get the page scanned later today an upload it.

Regarding advanced base ignition time for emissions: When I mentioned
this last year, people jumped all over my case. Is one of the reasons
I quit the Forum. Now you're saying the same thing! Go figure.
Domestic auto manufacturers *DEFINITELY* 100% unequivocally inarguably
(etc) did this in the late 1970's. I know because I have identical
engines spanning three years if production. Every year base ignition
time was scooted up a degree or two, with a corresponding drop in
performance (screwed up overall ignition advance)

BTW: Not all emissions are tested at idle. I watched the state of
Virginia do it to my little brother last year on a treadmill at speed
for 20 minutes or so.

Volvo alternators are located where DeLo exhaust swings around to the
muffler. I do believe Wilhelm specifically asked about "F Series"
(Volvo) engines... Same comment Re: oil pans.

I never wondered about "why" the series 038 CPR, I just wanted to
ensure it was proper for my block before spending $75 on another one
(remember: I asked you BEFORE I started buying my own factory
literature). My spare 038 is currently in service on Louie's otherwise
stock DeLo engine. I think he's become rather enamored of it. Wonder
if I'll ever see it again (without popping HIS louvers)? If my
carbureted swap works out OK, will be a moot point.

Urp?
