I have recently completed a B&S vertical shaft to horizontal shaft modification, was just wondering how it make sure I did it right and that I am not burning out my shafts. is there a smell or smoking that will occur if I did it wrong. also I was not able to change the flywheel and am still using the light weight aluminium one. if I am able to get it started will this wreck the engine or is is change just to make it easer to start. Thanks for your input for any one who posts.
