My carb keeps fouling. Every few months I have to pull the top off and clean out the gunk that's accumulated in the bowl. I've obviously got stuff in the tank. Think it's worth a shot to drop the tank and blast water in there with a hose? Or is there a better way to clean it out?

Definitely NOT water! But you have the right idea.
There are products made specifically for cleaning out fuel tanks. A lot of the folks here can give you names of great stuff to use.
But I wouldn't stop there.... I'd either remove the fuel lines and clean them out, or replace them also.
It sounds like the fuel pick-up in the tank is clogged or bad and is allowing crap to run through the lines. You may find that it needs replacement, if you can't get a new pickup screen/filter for it.

Good luck!

Great. Thanks for the advice, Joe. Come to think of it, blasting water into a tank that already has a rust problem would be pretty stupid. Anybody know the names of any tank-cleaning products that Joe's referring to?

Por-15 makes a tank cleaning/sealing kit. Don't know anyone who has tried it though.
www.por-15.com

look under "auto fuel tank repair kit" in the products section.

Definately drop the tank. For the cost, you may want to put a new one in. I did ( after clear coating it with POR15 Glisten PC - came out sweet ). An inline filter would help.You need to eliminate the source. The gas line should clear itself out when the stuff stops coming through.

I thought about replacing the tank, but it looks like you need to weld the filler neck to the tank. Since I don't have a welder, that's not really an option. I like the idea of an inline filter, though.

If you have a 67/68, there's a rubber sleeve that connects the neck to the tank - commonly available. The 69's are complete.

After you drop the tank (always always have a fire extinguisher handy!) and empty it, take a look inside. It may not be as bad as you think. My rusty old original was spotless inside when I dropped it. Let it dry out for a few days and peek inside. I vacuumed mine out and checked all around the insides with a telescoping mirror. I was amazed! Maybe yours just needs to be cleaned out and a new filter put in-line somewhere.
Check out www.por15.com and look at their fuel tank kits. They have a repair kit ($49.95) that'll freshen it up if it's really bad.

Sorry! Didn't mean to duplicate Mbrekke!
