Hi all,
I've finally reached the point where I can start driving my '77 Spit
1500 but a problem has come up on only the second day.
I had the car idling flawlessly at 600 rpms for the first day. Man I
tell you it was running so smooth and quite when I would kick into
nuetral from 4th (when stopping like approaching a light) I would have
to look down at the tach. so I could tell the engine was still
running. Now, unfortunately, when I look down, the ignition light is
on because the engine stalls.
Here's what some checking has produced:
1. I can't find an electrical problem (spark is good) and of course,
compression is great on the newly rebuilt engine -so-
2. I'm thinking fuel... I checked the fuel pump (which is electric in
the trunk). I hooked it up to a gauge... 4 lbs constant pressure.
Is four pounds fuel pressure okay?
3. I checked the carb. This is where I think the problem is. I pulled
the air cleaner and looked down inside... Fuel is being dumped into
the intake (at idle) and it appears is flooding/fouling out the
engine. I opened up the carb's bowl compartment and reset the float
assembly (the float "level"). I ALSO INSTALLED A NEW INLINE FILTER
into the fuel line before the carb. I also checked the little screen
filter in the fuel inlet of the carb itself. It seemed clean. Next, I
reassembled the carb and started the motor. It ran fantastic again,
like before. I looked down inside the carb and it was dry, no fuel
dumping! I then took it for a ride around the block. It ran great. I
took it out on a main road and accelerated up to 45 mph... when I came
to the next stop boom--> stalled again. It ran sick all the way back
to the garage. I removed the air filter and looked and sure enough,
excess fuel dumping again.
What do you guys think? Dirt getting inside even though I installed a
new filter? Bad float? (It is brass and is not leaking).
Okay, at the risk of being lengthy how about this:
I checked my back room and discovered another weber carb (DGAV 5E)
which a guy gave me after cleaning out his garage... it was very
similar the carb which came with my spit. I removed its float and
needle assembly and installed them in my carb (they fit perfectly).
(This was a plastic float) I set the new "plastic" float level and
re-installed in my car... SAME PROBLEM! Fuel dumping! I even
re-assembled the other carb enough to mount it on the spit and tried
it! SAME PROBLEM on the whole new carb--still excess fuel. I finally
gave up and re-installed the original carb.
The only thing I can think of is dirt or fuel pump. I did, just prior
to installing my rebuilt carb, flush out the fuel lines. I pumped the
tank dry. Then I filled it with new gas... then pumped the lines until
the new gas came out. (I never pulled the tank). And tonight, like I
said above, I installed a new inline filter...
Any ideas guys?
