So,
I'm running a 1.8L stock Vacuum advance dizzy with single weber (i know...not ideal) and as I've learned the advance curve is wrong for this setup and I have pretty bad lag now before 3000rpm. I swear the engine is running hotter now. Is it because the timing is too retarded in the lower rpm range? does that affect engine temperature? Anyone running a similiar setup with a suggestion as to where to set my timing to get better performance? I don't rev it up much past 4500 Oh, and I just ordered a a centrifugal advance dizzy, if someone is using one of those with a single carb and is having luck, please tell me your settings. Thanks. |

QUOTE Does timing affect engine temps?, I swear my engine is running hotter... ABSOLUTELY!!!!! Timing is EVERYTHING to head and oil temps! TWO degrees can make 50+ degrees of head temp! Retarded timing = higher exhaust gas temps because the burn is slowed and is still occuring while the exhaust valve is open.. High EGT= higher head temps because the port soaks all that head up and spreads it over the heat... Better get this squared away or you'll be a statistic! (IMG:style_emoticons/default/agree.gif) I am doing an engine rebuild bacause of too much timing. These engines seem to like a little more advance on the bottom end, it's definitly snappier. BUT with a mech. dizzy, anything you do on the bottom affects the top. it don't take much on the bottom to go over the top (IMG:style_emoticons/default/biggrin.gif) I can't wait to get my enegine running with the EDIS system to play around with this |
