A customer approached us about installing a used (1275cc) engine in his '69 sprite. The customer and I drove about 250 miles away to pick up the engine. I took a borescope along to check out the internals of the engine in question. The seller said the the engine was a relatively fresh reman, and gave us a short back story on how he got the vehicle and engine. We loaded her up and off we went. The job went as smooth as one could expect, I painted the engine and cleaned the engine bay up, installed the engine, and installed all of the accesories off of his (well running, but severely knocking) old engine, carbs, dizzy, water pump, the whole 9 yards. The engine fired right up without any issues, no knocking, no overheating. So I turn the throttle a hair and it puffs a cloud of raw fuel out of both carbs. My first instinct was CHECK FLOATS. Float levels were a bit high, so i adjusted them down to about an eighth inch while the bowl cover is held upside down. fire it up, same issue. So I checked timing (set to 10 degrees at 1000 RPM with advance disconnected), fuel pressure (a nice steady 3 PSI), Checked valve lash (and subsequently had to re-adjust the valves to .012in) checked cam timing, firing order, spark strength, thoroughly checked for a vacuum leak, and I have turned every screw on the dang carbs. It has 2 SU carbs, which in my eyes, are beautifully simplistic. I have adjusted the carbs full lean, full rich, and just about everywhere in between. I have tried ATF in the dashpots, tried 10W30, and I have tried 20W50, All yeilded the same results. The engine also seems to bog/miss while increasing the RPMs until you get to about 3500 to 4000, and even then it seems to really lack power. Has anyone ever run into any such issues? Im kinda pulling my hair out over here.
Any advice would be GREATLY appreciated.
