[Healeys] Carb jet tube clearance

[Dave Schweninger]

Hi Guys
I'm really curious about this. When I installed my steering column I  
centered it in the instrument panel and let the rest of the pieces  
fall where they may. I just looked again and every thing is on dead  
center, fire wall, big column brace and the instrument panel.
I keep hearing that "No two Healeys are alike". However I don't think  
that answers this discrepancy. Obviously these cars were put together  
in an assembly fixture. Even with sheet metal wandering around as it  
does, the steering gear would have to move to the right about 5", or  
the scuttle about 1/2". Not likely.
Dan's picture shows his engine side to side alignment to be almost  
exactly the same as mine. however vertically it's about 3/8" Higher.  
I'm beginning to think that the difference is in the intake manifold.  
Also not likely.
I measured from the steel heat shield to the carb face at the air  
cleaner 4 17/32".
The jet is 1 15/16" long from the carb flange.
Thanks
Dave
