Hi all, just bought the car, couple of little niggles, particularly once its warm or if I go to restart it shortly after turning it off. Sometimes takes a bit of churning and foot on gas to start before it chugs into life. It runs perfect when its running though. Doesn't use any oil or water, plenty of power, idles and revs cleanly etc. Is this common? It also has a blow from the exhaust manifold or gasket could this be related?
