In your other threads what you described seemed to be caused by an initial fuel line problem, then by changing the needles, you ended up with a new hard to tune engine.

If the needles are left alone on the T.H. it will start up right out of the box. You can run a couple of tanks through it as it comes then start tuning it.

I've done many this way. The only time I've had problems is when I did not follow this proceedure.

Usually it's start, run a few tanks, tune and fly with them.

They are not bad at all.
