Rick....I owe you a response from another/different post of mine. I was trying to figure out how the smoke unit was mounted in the engine shell.
There's a front bracket that screws to the smoke unit and the engine shell. I removed the bracket but the smoke unit was still solid in the shell.
The smoke unit has a friction fit with the shell's stack. Once I nudged the unit it popped loose from the shell.....a lot less complicated that I thought it might be!
