I am the original owner of a 1973 MGB with 227,000 miles on the odometer.
A couple of years ago with the last rebuild, I\we installed a Petronix's ig=
nition and had Mr. Johnson rebuild the HIF4 carbs replacing the throttle bo=
dy shafts. I had rebuilt the carbs a couple of times in the past but never =
had the throttle body shafts replaced. This was the best things I\we had do=
ne and wish I\we had done this 5 years ago. The car starts on the first tur=
n of the key and idles and runs great. Any starting or idle issues , I woul=
d highly recommend doing these 2 things. Cost about $400. What a difference=
! Of course always carry a new set of points, condenser and rotor in the bo=
ot in case any issue with Petronix. The look is stock above the distributor=
cap with one extra wire and the way it starts, runs and idles, these 2 ite=
ms, in my opinion, are well worth the cost.
To determine if your throttle shafts are leaking, start car and at operatin=
g temp, spray some carb cleaner around shafts. Any change in idle RPM'S ind=
icate shafts are leaking air.
Regards
Joel Martin
