Hey guys, I'm trying to have my engine stay running. Whenever I start it, it stays on for about 5 seconds then just shuts off. I had to replace the carb because I tightened the HSN too much that the housing broke. I took a carb off my old nitro because they're the same carb. I did set the needles back to factory and I noticed that gas came out from the exhaust so I tightened it 1/4 of a turn then no gas was coming out then. The engine was flooded but that shouldn't be the reason why it keeps shutting off. Please help! I'm getting quite frustrated with fiddling with it:/
