Well, the 40 is back together and running, sorta. It won't stay alive unless the choke is out at least an inch, or I am on the gas. The brakes hiss at me (vacuum??) and don't stop well even after a new booster and changing/adjusting/bleeding the system. I have about 3 vacuum hoses in my engine bay, mostly not leading anywhere. Oh yeah, and I have more exhaust exiting forward of the rear wheels than behind them where it should be. Where do I start??? if i fix the vacuum, will this help my brakes and the running problem?? I plan to get a header (don't know which one yet) to fix at least one of the exhaust leaks, but that is $150 i don't have. HELP!!! I need the most bang for my time/money. Thanks for the help....
