My ambo carb leaks and back firing was due to incorrectly adjusted
throttle cables (one side was always open). Once I fixed that my gas
leaks and backfiring stopped. Just another thing to check.

Steve....welcome to the best group the biking world has to
offer!

First of all don't get frustrated with these bikes....they are
very simple and if you apply a couple of philosophies you can't go
wrong. One of those is "for every problem there is a solution". The
other is that "you can do anything.....just takes money" :-)

OK...to your bike. You were right on with getting the points,
timing and valves sorted out. Next is to get cheap inline fuel filters
on and get the carbs cleaned out. The carbs are very simple....just pay
attention to the orientation of the slides and the little jets. The main
jet is the one with the bigger hole.

The reason the fuel leaked into the engine was that the float
needle (the little needle that shuts off fuel is worn....or has crap in
it. Get it changed.....cheap fix. Call MG Classics or MG Cycle for the
parts.

Once everything is cleaned out...set to the factory settings
(read the manual) and the bike should fire right up. Fine adjustment can
be done after that. My 70 Ambo came complete with carbs full of rust.
All I did was clean them out and the bike runs terrific.

Of course...keep asking us...we'll help you through all the
rough spots!

Regards...Ian

Hi everyone,
My name is Steve Farris, I live in SW New Mexico, and
have been lusting after a Moto Guzzi for 40 years. Recently I broke
down and got two old loopframes, a "71 Ambassador and a "72 El Dorado.
While both start, and drive neither runs well enough to want to take it
much further than the nearest gas station. I'm hoping to use the parts
from both to get one running well enough to have something to play
around on while I tear the other down for restoration. I found Greg
Bender's website via Guzzi Tech and he has been kind enough to give me
some advice about my Eldo's clunking rear drive line which I am
currently investigating. Here are a couple of other questions for the
group, please excuse the fact that I am new to guzzi's and haven't got a
clue.
1) the ambassador starts ok and has decent power but
backfire's constantly. I cleaned and reset the points, and reset the
valves. It runs better but still backfires (not as bad). My friend who
has a '72 eldorado says he thinks it is pulling air in around the
exhaust nut on L cylinder (it has stock nuts which are in pretty bad
shape). I am planning on replacing with the newer two piece nuts, and
also heard that the condenser could be the problem so will replace that
as well (do I need guzzi condenser or will something from NAPA
suffice?). Any other suggestions as to the cause of the backfiring?
2) I had the rear wheel off the eldo checking brakes
and wheelbearings for source of noise coming from rear end. Bike sat
about 3 days after I pulled wheel cause I have been too busy to mess
with it til today. I went out this morning and started it up to put it
in gear and see if the noise was coming from the u-joint. When I
started it, it began blowing liquid out the crank breather tube. I
opened the oil filler plug and the crank is full of gas/oil mix all the
way to top of filler plug! I'm assuming this was somehow caused by me
leaving the fuel petcock on for several hours the day I took the wheel
off? Any ideas, suggestions, should I shoot myself now or continue the
torture for some time further before dying of a broken heart?
Thanks
Steve
PS the PO has the fuel crossover hooked up without any
in-line filters could this in any way exacerbate my problem?
