tower 46 question
 

My tower 46 pro will only start if you put your finger over the carb. Is this a tuning problem or something else

RE: tower 46 question
 

You are not providing enough information.

Are there bubbles in the feed line?
Have you tried richening up the high-speed needle (try 2 - 2 1/2 turns open from fully closed)?
Did you mess with the low speed needle? -- Try turning it 1/2 turn counter clockwise?
Is your pressure line plugged?
Have you tried changing fuel lines (including tubing inside the tank)?
Is it an inverted mount?

We need more to go on -- describe the set-up in some detail, as well as all of the remedies that you have tried.

When you first fuel it up, you will either need to spin the prop with the starter for a few seconds, or put your finger over the carb and turn it over about 4 turns to get the fuel from the tank into the carb. This is normal. Is this what you are talking about?

I would be careful firing up an engine with my finger over the carb, thats pretty close to the prop. If you have the starter in the other hand thats a recipe for a couple dozen stiches.
If you are just trying to prime, like Fatsky, said thats normal.
