[alfa] Biba's cutting out...again



Without repeating Charlie Slayman's helpful suggestions as to trouble
shooting my intermittent cutting out situation, I'm am going to
concentrate on the fuel delivery situation - which will probably include
(as he suggested) running wires from the fuel pump into the interior and
hook up to a voltmeter.

If one recalls, the 'sight glass' between the two carbs was only a third
full yesterday - both at rest and when idling / revving at standstill.
Just checked and it looks like a level with just one bubble, meaning it
is virtually full to the brim. Started it up, revved it, and it stayed
completely full.

Somehow high heat (it was close to 100 yesterday) combined with a
longish trip (40 miles round-trip) causes the fuel pressure to dwindle
down to a trickle. This is why it is fine going 'cross town' but not on
freeways especially when revving fairly hard while entering a freeway.

Fuel tank was removed and checked about five or six years ago and it was
pristine. I am going to (once again) put on a fresh rear fuel filter.
I'm also going to 'borrow' the condenser from my other MarelliPlex. Am
beginning to wonder if 'condenser' is actually a static supressor since
it is mounted on the coil / heatsink and attaches to the - RUP side.
Should it be of interest it reads (as best I can) - 5U0 (or 5JO) V.efl -
Magneti Marelli -
Made in Italy - FM P (Greek symbol for Mu or m) FO, 3.7 - 4G.

And am about to go on Google to see if I can find an appropriate 4 to 5
pound pressure inline fuel pump (no luck).

I bet anything some of you race guys who run with Weber (or?) carbs know
of a really neat fuel pump.
