Re: rebuilding a carb this weekend
 

yes i think you're right. the pebbles were curiously large. i'll try
and swap out the cannister (it's prolly 20 years old) and add the
filter as you recommended. isn't the charcoal usually bagged w/in the
cannister? i'm concerned there may have been internal damage before
discovery (i say there was a good 3 or 4 spoons in there). any
possibility of that?

That happens when you run out of gas sometimes. The high vacuum
involved trying to start it empty can suck charcoal pellets out of the
canister into the float bowl. My 258 does that sometimes. The best
fix
I have heard of and I should do it is to put a clear gas filter on the
charcoal canister line that goes to the float bowl vent.

Re: rebuilding a carb this weekend
 

I have a brand new canister and mine will puke pellets. The canisters
are very expensive.

There is a quick test for it if it has the vacuum purge valve on it. At
idle trace the canister line to the PCV line and pinch this line
closed. If the idle changes, the canister purge valve is shot and the
canister needs replacing. This 'normally' causes a massive pile of blow
by with oil shooting into the air filter.

If you have the canister that goes to the air snorkel, then the only
real thing to check is the air filter on the bottom and to make sure it
isn't putting a vacuum on the gas tank. (both type have a $2.00 air
filter on the bottom, different from the 'custom' inline one I was
talking about)
