Except it can't accelerate. I think I need to rebuild the carb but in the mean time I need to verify that I have the timing set correctly. The engine lable says 20deg @ 1100rpm, but with the "C3 Diagnostic Lead" disconnected. It does not, however, tell me where to find this. Can anybody out there help? Thanks!

With a new engine dropped in I doubt it is a timing issue. check temp before and after cat. Take a shop rag...have someone in the vehicle snap the throttle if that rag doesn't whip back towards you have a clogged or collapsed cat. If you use a temp gun and see very hot before the cat and very cool after that is the issue.....mac1833 mac1833 View Public Profile Find all posts by mac1833 Add mac1833 to Your Buddy List « Previous Thread | Next Thread » Thread Tools Search this Thread Show Printable Version Email this Page Search this Thread: Advanced Search Display Modes Linear Mode Switch to Hybrid Mode Switch to Threaded Mode Posting Rules You may not post new threads You may not post replies You may not post attachments You may not edit your posts vB code is On Smilies are On [IMG] code is On HTML code is Off Forum Jump Please select one User Control Panel Private Messages Subscriptions Who's Online Search Forums Forums Home -------------------- Cars Lounge     General     Acura     Alfa Romeo     Audi     BMW     Dodge     Ferrari     Fiat     Ford         Ford Explorer         Ford Falcon         Ford Festiva         Ford Flathead         Ford Focus         Ford Mustang     GM         GM Cadillac         GM Cadillac Deville         GM Camaro         GM Camaro Firebird         GM Chevy Malibu         GM Corvette         GM Fiero         GM Oldsmobile         GM Pontiac     Honda     Hyundai     Infiniti     Isuzu     Jaguar     Kia     Lexus     Mercedes Benz     Mini     Mitsubishi     Nissan     Peugeot     Porsche         Porsche 911         Porsche 928         Porsche 944     Rolls Royce     Saab     Subaru     Toyota         Toyota Camry         Toyota MR2         Toyota Prius     Volkswagen         Volkswagen Beetle     Volvo All times are GMT -8.
