You're welcome.
Let me share this, if you buy a new engine:
On brand new engines, their plastic tanks, caps and fuel grommets are literally air tight.
It's like sucking thru a straw, into a soda cup.
When you suck, air leaks into the paper cup, right around the straw hole in the cup, to prevent a vacuum.
If the straw was perfectly sealed, the paper cup would implode and crumble, if you keep sucking.
That's what happens with new engines.
The tank can't crumble, but fuel won't get sucked out.
The engine dies, for no apparent reason.
You open the gas cap to check.
Vacuum is eliminated, so the engine sucks gas and fires up!!
With the cap on, the engine creates a vacuum again, and the engine dies again.
So you open the cap, and the engine starts up again!!
For a quick fix, leave the cap slightly loose, so it can suck air.
(But be careful that the cap doesn't fall off.)
Orrr, stick a toothpick in the grommet where the fuel line exits.
In time, the rubber grommets loosen up, creating a tiny air leak,
just enough to cure the fuel delivery problem.
You MIGHT not have this problem with a China tank.
Hope this helps somebody.
Ask me how I know this.
