Hi Dan, What you describe certainly sounds like a fuel delivery problem.
To diagnose that I would suggest driving at full throttle until the loss of
power is really bad then switch off the ignition, clutch in, and coast to a
stop.
Remove the float chamber lids and see if the float is floating on fuel or
has "run aground" on the bottom of the float chamber. If it has then fuel
delivery problems are the cause.
My guess would be that the Tank Renew gunk has clogged up either the pump
gauze (if it has one) or the fuel filter or the carburetor gauzes.
I have not had a lot of luck with tank sealing products and would recommend
a new tank every time.

Subject: [Healeys] Loss of Power at High Speeds
Well we finally got my 64 BJ8 going but the shop is going nuts trying to
figure out why it loses power at top speeds. We have newly rebuild carbs by
Jim Taylor, newly rebuilt dist by Advanced Dist, new wires by myself,
recently replaced fuel pump, new gas line from British car Specialists and
newly cleaned and sealed gas tank by Tank Renew. I made them put a fuel
filter right before the carbs but they did not put it until after they ran
it a while. They have supposedly cleaned the carbs out (I had Jim Taylor
put in the grose jets for the floats during the rebuild). Could be they
didn't do a good job cleaning the carbs here. They seem to think it is
starved for fuel at top end. Any ideas?
Dan
