Hello, can you confirm to me that that 25hp engine have an 25mm carburetor? It it stamped 25 in the throttle body where the air comes in.

Hello, I have the same engine. There is a problem with the engine. The engine does not go at full throttle in gear. How can I reach you?

I picked one of these up a couple of moths ago. it shakes like dog shittin a peach nut. Any suggestions? I already cleaned the carb and reset the air mixture screw. Runs better than it did but still kinda chuggy.
