timing

Re: timing

Its 10* BTDC on leaded head or 6* on unleaded head. To find if your cylinder head is unleaded it will have a identification of the following stamped on the cyl head next to no 4 spark plug, L, P, PP, R, OR RR.

Re: timing

thanks , the head has an I stamp and have found out this is for an injection head ,as it is fitted with a carb i am getting confused???? internet seems to think its ok and just drive....

Re: timing

Most injection heads were manufactured for unleaded ,so a budget way to go unleaded as the head of the injection engine can have carb fitted, but not the other way around.

Re: timing

Hi, the injection head should be fine wth unleaded. Depending on which camshaft you have fitted it is best to set the timing at in excess of 3000 rpm. A good starting point here is 30° BTDC but the dear old pinto will take near to 40°BTDC although pinking may become a factor in the carb engine. Try 30° BTDC for a start and see what difference small increases make until you are happy with the rsults. My Pinto (injected) is happy running at 35° at the moment. It is difficult for me to set idle advance as the high lift/long duration cam makes idling a bit lumpy. Always mark the dizzy before adjusting so that if the adjustment makes things worse, you have a mark to return to where it ran OK. Good luck with it.
