It’s so hard to understand your posts. The muffler is correct for that engine. If you don’t like it then take it off. Not sure what you are asking.

It´s the bigger brother of  Super Tigre G.15 ,2,5cc engines .
Yours is the G.19, 3,2cc version , same stroke but bigger bore + more torque.
The bore (crankcase) next to brass nut which secures RC carb.
should be covered (JB weld) because  possible fresh-gas leakage   .

In french words,

combris ?.

BTW you can kill    this engine in short time ,
running @ all synth. oil RC Car Racing Fuel.
