I have just got my first four stroke I got it new of someone without any
instruction. can anyone tell me where all the pipes got there are 4 nipples
for pipes 1 is for carb other one for pressure what are the other two for on
ASP FS 70 AR Series 3:
"This is a new engine from China's longest serving engine
manufacturer and has the latest type crankcase, with the timed breather
exiting into the intake manifold giving the fresh fuel charge a slight
boost, from the engines bottom end pressure pulses, It also redirects
any unused oil back into the engine to improve internal lubrication,
not all over the inside of your cowl."
The reason i ask is i have the pipes on the way that i would a normal
engine (carb and pressure"exhaust") there is another pipe going from the
crank case to a pipe branching of the carb which i have put another pipe.
The problem is i can't seem to get any fuel from the tank to the carb and
cannot get the engine to run is there anything i am missing on setting up a
four stroke engine.

You might have the lines (pipes) from the tank swapped. One line is
clunk/pickup line to provide fuel to the carb. The other is a pressure/vent
line to your muffler tap. If these were swapped, you would have the
pressure/vent line connected to the carb. Inside the tank, this
pressure/vent line is usually plumbed to the top of the tank. The tank
isn't completely full, you'll just be connecting your carb to an air pocket.
This is usually a simple mistake especially if you can't see the where the
lines or coming from our your lines are the same color or are not marked to
distinguish the difference. I usually use pink/red lines for the muffler
line (pink - hot gas) and then I use a blue line for the fuel line
If that's not it, then the next step will be to hear how you are priming
