One more possibility on this subject. It is possible that if Len's BJ7 has =

out anything that is not O.E. including the specifications.
I do not think it is related to today's fuel vs. the fuel available when th=

Hi all =20
Just finished repairing and reinstalling the carburetors on my BJ7. I th=

engine speed should increase slightly when you lift the piston a very smal=

the car starts and idles nicely. Also sounds beautiful when I punch the acc=
elerator linkages. The problem is that when I get it up to 60-70 mph I get =
