Ive just bought myself an STS .28 and am having trouble getting it started for break-in.

I read here that they are HSN - 2 turns LSN 3 to 4 turns. I set it at these settings but it refuses to start unless the needles are just about all the way out.

I've sealed the engine (carby, backplate, and fuel nipple) and have got the needles just about all the way out.

It pretty much refuses to start unless the needles are just about all the way out.

Once they are all just about all the way out it fires up, and spits lots of fuel as expected.

Will these settings improve with time, or am I missing something here?

Does anybody know any tips on getting it running easier?
