Well, Here is what I have done.
I have 2 engines that are doing this. (had)
First, my RB WS7 did it. Now we find it is a linkage / throttle issue.
This is in the same car, same fuel tank.
Pressure tested tank and have not found any leaks.
No leaks from front bearing. (No oily residue anywhere.
Back plate and carbs have been sealed.
I'll post needle settings.
Funny, both seem to be running o.k. now.
I replaced fuel tubing, but, prior, I could not find a leak.
I suspect it's a linkage issue. Still trying to find it though. (to confirm)
