    piston trouble on msx150

    the trouble is that I only get half rpm and the engine only starts on the initial start after that it will not start up till it cools down . I spoke to the dealer ad he tod me that the compression was good .I let a local mechanic listen to it while attempting to start it up and he told me that the piston was gone . Do I need to take the engine apart to confirm this . Alos there was a siver metallic liquid film on the plugs when I took them out . can someone help me here ..Got new battery and new plugs ..also replacing impeller as its all banged up .
