I was wondering if anyone knew the thread size on the seat on a holley nh carb - I had to drill one out by now need to re thread it.
The thread of the seat is: 1/4 x 32 NEF .
I always heat the carb. till the area around
the outside of the seat just start to red hot,
and then put them in water, then you can turn the
seat out whith a small screwdriver
