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. |

I will try not to highjack this thread but I think this question is germaine to the point:
As the motors (cars) get older, parts are exchanged or different mechanics perform creative adjustments, worn internals, new internals, etc... For those of us who have different combinations of cams, or carbs, or FI or distributors, how do you know when the timing is where it needs to be... By that I mean I have a Web Cam 73 and 1.7 heads but everything else inside has been converted to 2.0...Car runs great, pulls good throughout low and high range, idles very well and makes for a very good daily driver...The timing has been a challenge due to the bastardization of the motor...27 degrees will clatter the nuts loose, but at 9 degrees, she runs as described... Yes we would all like to have Jake motors, yes we would all like to have unlimited knowledge, but the facts are, we don't, won't, can't...Plus, Jake (and others in his field) live in search of the perfect motor...Great, we need those kinds of folks but there are those among us who cannot play in that arena... So, is there a sure fire method of determining exactly where the timing should be, so that a level 3 or 5 "do it yourselfer" will know the setting is correct ??? Ok, have your way with me... 2-OH! |
