So.... I've been ripping my saloon to pieces to get her back up and running. Carbs - rebuilt and incorrect bearing replaced. Carbs tuned - now sweet az :) Ignition New dizzy cap, plugs, points, condenser. Timing set. Gap set (29 degrees dweel but I can't be bothered fiddling any more). Ballast resistor bypassed (it was fuck*d). Rev counter disconnected then reconnected to rule that out. What is left? Well, I think the vacuum isn't working correctly. The pipe is clear. I can't work out if there is vac from the manifold but blowing/sucking directly into the dizzy vac connecting did nothing. When I drive the car uphill, she backfires out of the carbs and is down on power. Any ideas? This motor has come a long way but still not sweet yet!
