Hi all,
Finally got the motor fired up for the first time since I bought it almost a year and a half ago.
It runs, idles fine now I have questions.
I have a spare dizzy I got with the car which has a advance curve on it according to the guy who sold me the motor.
Its a Bosch Electric Unit, allegedly "recurved" for a 286 Cam I was told. My other distributor was being a pile of crap so in came this one.
Bosch JGFUX4 86BF12100BA 0237601008
Motor is a 681F out of a Cortina GT. Swapped Carb for Twin Weber 40s. Running electric fuel pump with FPR set at about 2.5LBS
Motor will fire up and idle fine, I have it set at 12°
Think my carbs are running rich at the moment but that's another thing.
Talking with another fellow he mentioned I need a timing gun where you can set the timing on it..
As I had my gun on the timing marks and revved up the motor to over 2500 rpm I didn't see the mark advance at all.
Questions are as follows..
-It is perhaps advancing and I'm not seeing it with my old fashioned gun? (No backfires, no hesitation when I blip the throttle) It's running an open header right now so I do hear a pop from the rich mixture I have at the moment.
-What is the ideal amount of advance for my setup? How can I find the advance of my distributor and the best way to match the timing of my motor to that.
-Is there any danger to running the motor with an advance curve that is not specifically dialed in for my camshaft. Should I be pulling the distributor apart and adjusting the weights inside?
If my questions seem quite novice I apologise just looking to learn and for any help anyone can provide.
Thank you very much!
