I just finished an engine swap on my 87 t2. The engine i put in had compression of about 90 for both front and rear (better than the blown engine that came out :P).

I have the racing beat turbo back exhaust and a 255lph walbro fuel pump. THATS all for engine mods. Im running very rich, like 10 mpg rich and blue smoke when i floor it.

Im not sure what im boosting since i dont have an operating guage but im guessin its around 10psi.

What are some components that might be bad that make it run really rich? I just want a list of all the possibilities. I know it needs a rebuild but it runs fine for now, just wastes gas. Thx.

anything to control the 720s?

its the Fuel pump that is making you run rich...i believe(dont quote me) i also run rich due to that same pump.....buy a Fuel pressure regualtor or a piggyback fuel system or stand alone system and control it....

I dont have 720's in the car atm because i didnt have an rtek or anything. I dont think its the pump because the stock 550's would limit the flow but I may be wrong. Any other ideas?
