[Surcouf]

you did half of the job!! well done!


my 2 cents, but MVP's opinion are more valuable (by definition):
You should remove the carburetor for sure if not already done, clean it, then spray compressed air (those keyboard cans come handy) into the manifold before installing carburetor back. Regarding whatever is left in the pistons, a few seconds cranking will get rid of all that (if you really have a lot pooling in the pistons, crank without spark plugs but it is going to spray mix everywhere around the engine).

But once you fire it, make sure to change the oil. Not sure if the acetone and all the mix sent is very good for lubrication system..
