Hi ,
I am new to the 911 world. Has been a BMW E24 fan since high school. Owned 630 to M6 even a 3.0 CSI once.
I just got a 75 911S. The car is in good overall condition.
It has a Perma Tune CDI unit (silver one). I have a no spark condition when the ambient temp is below 16C. This morning it is 13C in Calgary and I crank it and no start as expected. I took the CDI unit off and place it on the stove to slowly heat it up to 40C and re-attach it to the 3 pin plug and it start right away. (the whole procedure took 15 min and the ambient hasn't change by more than 1C)
Anyone has similar situation with Perma Tune or other CDI units. (ie warm=easy start; cold=absolute no start)
Any comment as to what may be the cause of this situation.
Thanks
Ed
