powersmoke 740 smoke pump leak
I have a emcotec powersmoke 740 smoke pump that is beginning to leak at the face plate. The two screws that hold the face plate on are tight. No leaking is apparent from the fuel line connections on the face plate. but after each flight there is a small quantity of smoke oil below the face plate.I am hesitant to open it up not knowing what i will run into.
Has anyone seen this problem, and if so were you able to fix it without send it back to the factory? I am guessing it is a o ring problem but am reluctant to open it up.
Thanks for any help you can give me,
Stan

I'm bet it has an O ring like the others, I handle a few Tamjets ones throughout the years, Tam used to work on his pumps before shipping them to make sure they worked, the key here is to tighten the two screws back on just enough to allow the gears to run freely, there is a point where the plate presses on the gears and it's hard for the motor to move them.
I would lube the O ring with thick O ring lube first, if that doesn't do the trick, change the O ring and reset the front plate to the point explained above.
Fuel pumps are the same way but way more critical.
