I had similar troubles and used a similar solution. I bought my 83.5 Westy
in 94. At the time it had 29k miles on it (yep, 29k). The PO kept it parked
out back a lot. Trouble was he stored it with only about a quarter tank of
gas. Much gunk in there when I bought it (and if any of you noticed a sudden
shortage of fuel filters in the latter half of 94 it was because I was
cornering the market).
   For a while I was pumping about as much fuel system cleaner as gas and
changing the filter about once a week along with regular blowing in the fuel
line. BIG pain-in-the-butt but the clogs gradually decreased in frequency
then finally disapeared.
