hey guys, i need some help - i own a 1976 porsche 911S, model 930, and i have a problem with it... it seems to me that if i turn the car off immediately after racing or driving really fast, the car will have trouble turning back on (say, after i finish my meeting or after i'm ready to leave work and head back home). Its a bothersome issue because i've had to push it to drop the clutch every single time it did that...

any suggestions?

i was thinking it might be the fuel pump and/or the spark plugs, or maybe the fuel line is clogged... what do you guys think?
