timing issue?? My problem is im not sure if the timings right on it? after the car has been running i will turn it off and when i get back in it about 5-10 minutes later it wont fire right up i will have to hold the pedal down as im cranking it!! being that its brand new i think it should start up fine? it has a new starter new spark plugs new msd distributor, new msd super conductor wires, edelbrock 600 cfm carb edel intake it also has a crane cam rough idle!!! is it have something to do with the timing? if so what sould the timing be set at for the 350??
