Newbie to Porsche ,72 T Will not start. cranks fine, gas smell,coil firing to dist.cap,(yellowish spark) wires have fire,timing set at Z1,#1,XR-700 set best I can from right to left,new coil, new wires,plugs,and cap. cold start should not be dirty yet, has gas, fuses good,grounds good,resistor resist, firing order correct. spark from coil to ground yellowish. grey wire to cold start on filter connected. recent valve gapping done,(not by me). was running in last 4 weeks, let it set and now no start,no other work done on car. recent mileage for tensioner upgrade. i am prepared to replace xr700 with points next. As I understand timing s/b to Z1, idle to 5ATDC. The dist. was not removed until I did it today to just check for the 180 thing.no results there. I know it must be something easy. thanks ed, em
