Smoking 2F engine (1 Viewer)

Anyone know why my 2f engine is smoking. I'm just starting my project '75 FJ40 from 4 years ago. I've done compression tests and cylinders 1-6 are 142, 145, 143, 140, 141, 140. When it runs, it smokes like a chimney and spits black soot out the tail pipe continuously. The head was reworked and valves/seats ground and stems knerled. New gaskets all around on the top end. Running a Weber carb. A strange mechanic said the oil rings were put in upside down and it's pumping oil up instead of pushing it down. Is that possible? Engine was "supposedly" rebuilt two owners ago. Odometer reads 87,000mi.

Black smoke is from burning a rich mixture; not oil.

read the plugs

pull your plugs if they are sooty and black---too rich
or if they are black and oily ---oil fouled

Spark Plugs

but like Pinhead said it is usually a case of blue smoke for oil and black for mixture

Sounds like carb . Mike

Strange indeed........

I'd stay away from that goofball........

Check the sight glass in the carb.....your float/needle and seat might be plugged open with crapola allowing the bowl to fill and spill over into the carb.
And make sure the choke is open.
