I am rebuilding my 4160 reman carb ( It dried out during storage).
Problems I had leading to this, I can see gas running down the secondary's while it is idling. Also leaks behind the vacuum unit( for 2ndarys) and same location on the drivers side.
I see that the rebuild kit has a acc. pump diaphragm - the rubber is black, I'm reading that there is a green one - made to resist the ethanol affect.
Can someone let me know if there are any other parts I should replace in the kit that are made to work with the ethanol in gas?
Thanking you in advance.
Ethanol will corrode the metal parts and deteriorate the non-metal parts throughout your fuel system, especially if the car isn't driven daily. Try NOT to use ethanol fuel...
I'm suspecting that this government mandated 'ethanol' in fuel is just a means to kill all our older equipment and make us buy new... It certainly doesn't help anything else. My car even gets 10% less fuel mileage when running 10% ethanol...

A good rebuild kit will have a new diaphragm for the vacuum secondary actuator.
NAPA sells a gallon can of carb cleaner it comes with a basket for small parts it is the best cleaner I have used the carbs will look like new after letting the parts soak for awhile. Cost was around 25.00 a few years ago.
I was able to overhaul my carb, put it on the car and it starts and idle's well.
Best as I understand, the holley kits are set up for ethanol.
I did replace the diaphragm with a holley part , they say is ethanol compatible, it is green in color, you can see it in the photo.
Time will tell.
