It sounds like the muffler may be worn out, or the engine may be over revving. To Check the muffler you tip the mower on its side and look where the muffler outlet comes out through the slot in the mower base and around the bottom of the muffler. If there is a hole blown there or a series of small holes, the muffler has rusted or burnt out, and needs to be replaced. Or possibly when the Carburettor was replaced the engines governed speed has incresed as a result,and may be over revving. making it vibrate, As these Victa engines can get very loud, rough, noisy and hot when they over rev. Also check that the vacuum hoses heve been connected properly,
Let me know how you go
