Seca II fuel issue...

Howdy.

I was gonna go foothill riding with a friend yesterday, but his Seca
wouldn't start. Here's what we checked:

--Getting spark? Yep, pulled the plug, not fouled, grounded it, cranked
it, good spark.

--Fuel out of the tank? Yep, flows fine on prime.

--Fuel at carb intake? Yep, flows right outta the fuel line.

--Carb fouled? Doesn't appear to be; we tore apart, no gunk, particles,
didn't notice anything "stuck" or whatever.

So he didn't get to ride and now we are both stumped. I guess he's
gonna have to have it towed in to the shop...unless someone on here can
give us a last minute suggestion....

p.s. It was running fine so this was very sudden...not a gradual thing.
