and now that it's really cold out you probably need a hotter plug. I went out today and had to switch mine out to a hot one.

Factory settings are normally way to rich. Set the idle like others said and use the HSN at first. If raw fuel is dumping out the pipe, keeping going in on the HSN until it's not spitting it out the pump so much. Do wot runs and listen for the top end to peak out. Once that is set, then adjust the LSN to get the rpm's to drop down after the wot run. Like others stated, if it's cold out you will probably need an ultra hot plug.

So will the buggy dump fuel at idle if the HSN is more lean?

Sounds like I'm going back to factory.
