HURRAY! IT LIVES!
Well today was spent putting the engine back together, gutting out the muffler, drilling outlets in the muffler and finishing the test stand. When all was finished I tried to turn the engine by hand to get a feel of the compression (No fuel or ignition) and instantly the prop sliced my finger! Ok dumb boy put the gloves on! Fueled it connected the glow plug diver and on the first flick the engine started!!!!!



The only problem now is that it wont stay running!
So here is the question On the carb there are two fuel pipes, on the tank there are two fuel lines. On the last attempt to start the engine I connected the fuel outlet from the tank into the top brass pipe (nearest the glow plug) on the carb, at the rear of the carb (rear of the engine) adjacent to the throttle linkage. the other pipe I connected to the primer bulb then to the other brass pipe on the bottom / front of the carb. Is this the right way on a Walbro WT391? I couldn't test it again as my glow plug driver ran out of charge and I won't be able to test it now until the weekend.
Nearly forgot, both of the mixture screws are 1 1/2 turns out.
Thank you.
