 This is in reply to Frank Burkhart about his carburettors.
 It sounds as if you carbs just need a rebuild and this is easy to do yours=
elf if you are in the least mechanically minded. Just go to "Buckeyetriumph=
s.org and look under" technical" and you will find comprehensive instructio=
ns how to do this amd tune them up. If you are not mechanically minded send=
 the carbs to Joe Curto in New York his E mail is [email-masked] and phon=
e is 718 762 7878.
>From your description of the engine being awash with gas at start up it sou=
nds like the needle jets are stuck open or the floats are full of fuel.=20
I was not aware that Apple Hydraulics dealt with carburretors and replacing=
 a piston in a carb is not to be done since it disturbs the original carb s=
et up and I can't see why a piston should be damaged beyound repair anyway.
As your car is a '76 if you live in California you cannot replace the carbs=
 with SUs because it would fail the emissions test.=20
Just stick with the Strombergs and do't let anyone tell you that SUs are be=
tter. The only reason Triumph and other British cars manufacturers changed =
from SUs to Strombergs was because of emissions. SU was obviously not prepa=
red to put the development work in to make their carbs emission compliant.
