Older K&B .40 Marine engine - Assembly question

[Jeff Baggett]

I have an older K&B .40 Marine engine. It has an older type rear induction (carb on the rear). I took off the rear housing to change the gasket, and I did not pay attention to how it came off. It has "slots? that line up with the bottom crank....I do not know how to line this up. It also seems like I get a lot of blow back out the carb when running. I thinjk it is called a disc type valve..Can anyone help me line this up properly? Thanks Baggett@triad.rr.com

The carb is on the upper part of the cover. Line up the casting...
