Hey guys.

I recently crashed my trainer so I'm just dusting off an old low wing seagull space walker that I bought second hand.

The engine is mounted upside down behind a cowel. I seem to be struggling starting it. I've stripped and replaced the entire file lines and still no joy.
Pis there anything different I should be doing to run it?

if I prime the engine it will run but then cuts as if the fuel isn't getting through. If I blow down the line connected to the muffler it will come easily from the carb line so I'm a bit baffled.

Is there anything obvious I'm missing? If not ill just keep trying.
