I have had the same problem with a 69 TR6 (Z-S) with Grose and it did not
go away until I replaced them with standard issue.
Steve,
The gross jets had a bad run a number of years ago. I therefore throw them
into the trash if I run across any. I once was left on the autocross
staging area @ a VTR National in Rockford, IL with my TR3B puking fuel due to
those _%*&^$#@%s_ (mailto:*&^$#@) !!!!! I also have had the standard issue
type go bad too. Just not as often. Normally if one taps the float bowl with
a screwdriver they will sometimes close shut. Dirt and contamination from
the fuel tank getting past the filter is usually the problem. I have even
seen little slivers of rubber hose clog the jets so make sure all fuel
hoses are in good shape
The float chamber ventilation that Dave speaks of is very real too. I
once washed out the rod bearings of my newly rebuild Spitfire 1500 motor due
to that problem. Gas in the sump!
Darrell
