Factory HSN setting too rich?!

[binspoonal]

Hi,

I think the HSN setting from the factory is too rich! I have a new truck and I'm having a really hard time getting it started. I was able to get it running once for like 5 seconds and it stalled, unable to start since. I've just installed a new long/hot plug. After trying to start for a bit, a bunch of gas came out of the exhaust.


Anyone know how many turns out from closed would be a good break in setting for the HSN?

Thanks!

Mine was rich like that also, it would push out a good amount of fuel through the exhaust. I leaned it out 1/8 turns till it kept running. And kept a good eye on the temps. As long as there is blue smoke.

Ok, I fully closed the HSN and turned it out 4 turns and it fired right up! finally..
