Got the moped and tank was rusty inside so cleaned it out and looks great now, took carb off and it was ruff so bought a new one, new fuel filter, lines, air filter, spark plug and a new petcock. Very hard to get it to start and when it does it only runs for a second. Did get it to idle for about 30 seconds and when you give it gas it die like you shut the key off. Tried starting fluid and it doesn’t do anything. I can’t keep it running long enough to check for air leaks. Any thought on this one ? I’m dreading taking the carb back off since you need to drop the engine.
