I am having a problem with the MOKI 180. It starts when primed, then runs for 1 minute, then stops.Runs out of the Prime.It is not getting fuel, the way I see it. I looked at the line to the carb., no fuel? Main neddle valve out 5 turns per instructions to start.
I pulled the tank, 3rd time, replaced all the fuel tubing outside the tank with 1/8" tubing and have put on clamps on the fittings. I pulled the fuel lines inside the tank, whichis 3?32" normal tubing and replaced. The clunk is fine,no obstructions.Pressuriezed the tank, no leaks. So now, I don't know what is happening.

I pulled the engine, inspected the carb, looks OK, nothing loose and O ring is good. The Low end diskvalve is centered with the grove. I richened, same problem, then leaned, same problem?
This engine is supposed to work with 3/32 "fuel line, which I replaced with 1/8" tubing, no obstructions whatsoever.
The fuel take is almost level with the carb spraybar. What is going on here? That thing should suck fuel like nobodys business. I am using a Slimline Smoke Pitts Muffler, with the Smoke port closed off, Not set up for Smoke yet. I have tried OS #8 Plugs, and K&B plugs, no difference.
The engine is mounted Horizontal (sideways). if that helps.
