<x-charset x-user-defined>A while back I wrote about having a problem with hesitation on acceleration, under load. MY car is a Carb'ed '69 T34. Well, after checking the carb for vacuum at different rev's and checking the distributor for advance at different vacuums I've reached the conclusion that I'm getting to much advance, to soon. My carbs are new and are giving 200mmHg vacuum at 1500r.p.m and 300mmHg at 2000r.p.m. - according to the Bentley for a similar distributor this vacuum should only be reached at 3000r.p.m (crankshaft). This is confirmed by the car performing very well, on uphills (under load) it runs well at about a 1/3 pedal, but lousy above that, worse, the more I put my foot down - I hear a Brrrr... sound from the back - I guess this is pinging?! So, what is the solution, less static advance i.e. set advance to 3 deg. BTCD instead of the current 7.5 BTCD ? Herman ------------------------------------------------------------------- Too much?
