yes i did mean the head, sorry i am still learning. and the D N had a screw between it and was pretty rusted so i was unable to see a arrow.

and i am having a hard time finding the number cast. Is it in the arear driectly where the distrubiter goes in? or...

i am sorry but i am still on a learning curve, and when i say curve it is a pretty straight line b/c i am brand new to working cars as of this year. A gas powered R/C car is as close as i have came to working on a car since now.
