Hello, I have a 1984 Honda Big Red Three Wheeler and it will not start. I have just put in a new spark plug (last one was fouled) and new oil because my local mechanic told me that the old plug was oil fouled and I needed to change the oil. So today, my brother said that there seemed to be old oil in the combustion chamber but I have no idea how there was oil left in the engine because we used the pull starter to drain all residual oil we thought there was out of the top end like the manual said too. Could starting fluid help try to get the thing to start and maybe get that oil out of there? Or do I have to take the thing apart?

Yes, try starting fluid.

I don't know if it has old fuel in it or not but if it does, you'll want to get rid of that and put new fuel in it too.
