I now have my carb on my 65 coupe and the engine sounds good, but I was pumping my power brakes last night because they felt spongy and I noticed a lot of blue smoke billowing out of the exhaust. Is this brake fluid being forced into intake manifold and is this normal? I notice that I am using a lot of brake fluid and I am not sure where it is going. I haven't noticed any obvious leaks, but I still need to check my brakes before I take it out on the road. Any help would be appreciated.
