Well hello all,
I finally had a nice enough day to get the spitfire out from its resting
place at the end of the driveway this afternoon. I didn't really have a
plan yet as to where i was going to start, so i just decided to fire it up.
To my surprise...it started!!!! However, it began SPRAYING fuel all over
the place!! So i had to push it into the garage. Tore the float bowls
apart to find that the front float pin was completely stuck shut. So i
fixed that up and tried it again. Ran pretty well for a while then started
sputtering. So here are my problems...
1.) the timing was off, to i had to retard the timing a little bit. Now it
is running much better with out the sputtering and backfiring. However...i
noticed that when i lift the cylinder of each carb (dual su's), i get a very
different response form the engine. When i lift the cylinder in the front
carb, nothing really happens. It runs fine and there is no response to
speak of. However, when i lift the rear carb cylinder, the car basically
stalls out. I checked the carbs with my tuner thinggy dinggy (yes...that is
a technical term), and they are pretty darn close to eachother. So i played
around with the jets and was able to get it to run a little better yet. But
i still have that same problem where the rear carb causes some sputtering
when operated alone.
2.) While it was running pretty well i got antsy and wanted to drive it.
Oops. It ran fine for a little while but once i got to the other side of
the neighborhood, it started running terribly. Sounded like it was missing
a LOT. Almost like i was only running on 2 or 3 cylinders. I was able to
hold on to it and get back to my drive way, but at that point it stalled and
wouldn't turn back on.
Any thoughts on these issues? i am figuring that the 1st problem just has
to do with tuning the carbs better but i am not sure. the second
problem...i really have nothing to go on. Possibly compression? I never
really checked that now that i think about it.
Thank you in advance.
