In 1982 you built a set of weber 48's (with 30 chokes and special jets) for my Ardun engine on my home built manifold. The first set of jets didn't work well but you created a new set that worked fine. I always appreciated the personal service you gave me. I think you might be interested that after 40 years on the road (67,000 miles and 48 states) your setup is still going! Looking back I made the right decision on buying one of your systems.
