Engine casing discrepancies
-
Is it normal for two casings to be different? Specifically the inlet porting? The right side case doesn’t match the left by about 8mm! It’s an old 3bn that I don’t know the history of (eBay). I’m guessing that they two different year casings.
Is it best to match them or is it normal?..

Just to embellish a bit. These are 3BN 01 cases. I have some 3BN 03 cases that are totally different. The inlet port that ‘ups into the barrel’ doesn’t have the step, but does have a ‘flaired up step’ that I guess directs gas flow up into the barrel port. I’m just wondering how many different variations of 3BN engines there are?
I’m guessing that the 01 & 03 numbers are the year?

I agree! The bits I’m on about are internal though
How do you post upload pics from a phone. Do you still need to host the pic?

I know it’s an old post, but I’ve only sussed out pics recently. Check out the casing join inside the inlet!...
What say yooz?... -
