Thanks for the replies, I ordred an Edelbrock 1403 500CFM yesterday and will install it next week, no driving the car till then. After installing the new carb, I will have to change the oil you can smell the gas in it.
My last Camaro was an numbers matching 68 RS SS 350 with a rochester carb it did the same thing when it was first purchased after been sitting for years.
The 67 i just purchased had been sitting for a while, this must be an issue with the rochester carb. Owner died. Widow sold car to me.
