As far as intake, I'm running a stock airbox with a K&N drop in filter.
If I start it with half choke, it'll run for maybe 30 seconds before it dies. With no choke, I'll run for a few seconds before cutting out. Starting with full choke then backing it off will kill the engine too.
When I get home today, I'll let it sit for a few hours to get the engine cold and then start it and check the plugs.
