tturnpaw Posted July 8, 2009 Share Posted July 8, 2009 I do know this has been covered before....I did a search and couldnt weed it out. Ok so carb was operating correctly before the engine swap. Then i dropped an spfi engine in and swapped the manifolds and distributors. Problem was, a lot of vacuum lines were plugged or missing so i tried my best to plug most of them off depending upon how they were run. Everything goes to a source or is plugged off. Ok so after timing it and etc. I dropped some fuel down the carb and it fired right up. The fuel lines were installed correctly as i double checked with another car. The problem is either tapping the key a few times or firing it, fuel comes out the front out of the accelerator valve i do believe. I pulled the top off, checked it, cleaned and reset the float and reassembled and the same problem. Is it the plunger on the accelerator valve or is it a further float/needle problem? It keeps flooding the front right of the carb. Thanks Quote Link to comment Share on other sites More sharing options...
Loyale 2.7 Turbo Posted July 9, 2009 Share Posted July 9, 2009 ...carb was operating correctly before the engine swap. Then i dropped an spfi engine in and swapped the manifolds and distributors. ... So, you are Trying to Run an SPFI EA82 Engine with the Intake & Carb + Disty from the Carbed EA82 Engine? I Believe that There are other Background Differences Between the Carbed and the SPFI Engines` Setup, for Example: The Fuel Pump and the ECU. Did you Changed that Too... if Everything Related to the Carb is AllRight, you must Know that a Bad Timing in the Timing Belts (For Example: a Theet Off) Could make the Pistons to Blow the Air/Fuel Mixture... Was the Newer Swapped Engine a Runner? Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted July 9, 2009 Share Posted July 9, 2009 Did you lose the check valve ball from the bottom of the accelerator pump cylinder? It goes under the spring - it's about 1/8" in diameter and made of a nylon (plastic) material. GD Quote Link to comment Share on other sites More sharing options...

Was the Newer Swapped Engine a Runner? I guess i should have been more specific. The spfi engine came out of a donor vehicle, installed all new gaskets, swapped the intake manifolds and carb, and put the engine in the carbureted chassis. As for the carb, i tore it down, found the plunger to be very weak and not sealing, the needle valve wasnt seating correctly, and a bunch of dirt all over the place. I just grabbed my other carb off the shelf and no issues so far. Thanks! Quote Link to comment Share on other sites More sharing options...
