Hey this is kind of related to the last thread I posted, but I was just wondering what I can use to clean my engine with and my carb. I was told once but I forgot. Is it rubbing alcohol? Also, whatever I use, can I just like dip the whole part into the solution, whatever it may be, and let it soak for a while? One last question, when I am all done cleaning it using a given solution and a given method, can I use WD-40 for lubrication after or should I use something else for lubrication? Thanks a lot, peace.
