Hi Eric and List,
This comes under the heading of "other idea" I guess.
Is there a similar issue with "new" style Solexes? I have had somewhat of a
problem with Loreli. I don't get proof of running rich on any one cylinder
via spark plug inspections, but I have a "popping/sucking" type noise coming
out of the front carb (front of carb I think, #1 cyl.). It sounds a little
like a suction cup popping loose. It's not loud, but I'm sure it's not good.
It's too damn cold to go out and check valve adjustment. It's been like this
for 2 years, so I don't have any problem waiting till it is warmer to fix
it, but I'd like to have SOME idea where to start (if valve adjustment
doesn't work). Am I looking at head work? Carb rebuild? If I'm getting "blow
back" from the valves being out of adjustment, will a "flow meter" jump
wildly?
At idle, I can hear it maybe or 2, or 3 times per second at most (not 5.8+
as I would expect if it's only on compression stroke @ 700 RPM). I'm no math
genius, but I figured 4 stroke engine = 350 compression strokes per minute
at 700 rpm / 60 seconds = 5.83333 compression strokes per second.
Have any ideas folks? I think I asked a question similar to this previously,
but now I had a little more info to add. It's hard to ask the right question
the first time, I've found. :-) Right answers to the wrong question are
ALWAYS a learning experience tho!!!!! Gas tank half full, not half empty!
Thanks

There is a small brass blanking plug that closes off a drillway in the
cold start circuit on the old carbs. Sometimes it leaks and there's no
way you can tune this out without fixing it. The symptom is that the
engine runs rich on one cylinder. It can be fixed with a small brass
drift and <light> hammer tap or two. I have seen several old-style carbs
with this problem and it is easy to fix. The diagnosis is the hard bit.

he can't get the front one to work properly.? Anyone know an expert in the
Los Angeles area to deal with it, or have a front one that works to sell to
me, or have some other ideas?
