Thanks for the input. I'm ordering the viton tip needle. My fuel pump is
the stock mechanical pump. Can that put out to much pressure?

Others will disagree, I'm sure. But my first step would be to replace the
Grose Jets with the proper needle valves. I don't fully
understand why, but I've fixed several cars with similar symptoms that way.
Or if you happen to have an adjustable fuel pressure regulator installed,
try turning it down a bit.
