When I purchased this 292 there was no hose connected to the vacuum line on the distributor. There is a threaded hole at the base of the carb. I plugged it to keep bugs out. [IMG]http://i305.photobucket.com/albums/nn214/jfnar/68%20GMC/IMG_02001_zpsqiavozsr.jpg[/IMG]
Is this the correct location to connect a vacuum line for the distributor? If not, what is it for and where is the correct place to get the distributor vacuum? Thanks.
