stivic

Finally got it runnin today, found out the ignition problem was the dizzy itself. It fired right up no problem idle is a little high about 1k and when i rev up the valves knock a little what could that be??? I have an oil leak comin out of my valve cover but im gonna get a new gasket and fix that hopefully not havin tot ake it ot a shop, I drove it down the road and its fine until i hit 3rd gear and it has no power i hit the gas and it makes this weird vibrating noise what could that be???
