[Healeys] sticking valve

[James Shope]

i am working on a tri-carb that has been sitting for about a year in this
heat.  the carbs were all varnished up and took a lot of cleaning.  still had
problems and finally decided to check ignition.  no problem so did a comp
check.  #4 had 0.  pulled valve cover and saw intake valve push rod off the
lifter and lodged up beside it.  checked valve and it was stuck solid closed.
took two days of PB blaster and tapping on it every so often until it finally
was loose.  readjusted everything and had 150 psi like the others.  do not
know what caused this but maybe someone has had it happen before and can
enlighten the list.  also, the gros jets were removed and replaced with new
needle valves because they just kept plugging up even when the ball was down.
it is now running smooth like it should.  is Stabil in the gas a good idea for
this car?  never used it so am reluctant to put it in unless i get some good
testimonials.   hjim
