Hello
I am trying to get my old cream bonnet Cox ride on ready for summer.
Its GV400 engine has developed a knock which gets louder under load.
I have removed the engine & have it mounted ready to pull down.
I have bought a second hand GV400 ( blows smoke & hard to start ).
I also have another one I bought in pieces.
I have purchased a gasket kit & 2 sets of rings.
Would be happy to have one running out of the 3, then work on one as a back up.
After that back story, my question is what would cause the knocking under load? Should I start on this or rebuild the smokey engine.
