Faulty petcock leads to better performance??

Just wondering if anyone can weigh in on this strange phenomenon.

I think the petcock on my Aero might be stuck open because gas is draining out of the overflow tube pretty much all the time it sits in the garage.

I wiggled the gas line on the petcock and it started to leak as I pulled it off with the engine off. What I'm wondering is: could this possible increase speed by introducing more gas or something?

I ask because the thing was bogging and slow for a few days, it wouldn't pull up hills or even go over 1/4 throttle without wanting to die. But after I noticed the petcock acting up, the bike runs like a madman. Pulled me up a hill so fast the other day I slid back on the seat a little, which wasn't the case even before the bogging.

Thoughts?

No, it would not make it faster, if gas is coming out the overflow you need to clean the carb and possibly replace your needle.

I suspect you may have been running lean before.
If more fuel causes your scoot to perform better.
Most of the time, it gets to much fuel, or if the diaphragm ruptures, the intake will fill the engine with raw fuel.

I had this same problem with a clogged up carb. The day I got my se50p home, we put in some gas and started it up and then we shut it off real quck (no muffler) and watched our liquid gold start pouring out the back! A quick tear down and we found someone tried to clean the carb but didn't blow air or check for plugging. A few minutes later and no more gold leaks

check you needle and seat and make sure the bottom screw in the carb is tight
