I can't imagine why you need a 13 cycle clock, but any way here:

hi der i made 2 engines, one uses of sparkjet's engine block/cylinder concept and the other was my first engine. the first one isnt very good but here it is. also, the second one i think i need sparkjet's permission to use the engine block in an upload?

(this is my first engine ver. 2)

edit (this isnt my second engine, just a ver. 1 of the first):

i will add my second engine when sparkjet says i can use the engine block.(my second engine is much better)

hope i got that link thing right...

@sparkjet
can i use your engine block/piston concept thing in my second engine?

edit:
@Ace
you could have a 13 cyl. engine?


my second engine, much better than the first. thanks to sparkjet for the engine block/piston concept also, i managed to get it to run for an hour without exploding (then i got bored), but then i opened it just now and a cylinder popped in 3 mins?!

oh yeah and heres my first engine (its fuel pouring down a pipe, lol)

@cctvdude99 sure you can use it, but please give credit. :)

will do thanks =D
