Default RB WS7x2 questions

my picco rod went out yesturday so I threw in my ws7x2 back up engine not even a gallon on it. was only pulling around 7 mins to a tank in my RC8 with a RB#6 plug and jp-4 pipe...running around 220 with good smoke and everything

maybe I am just used to getting around 9.5-10 out of my picco but 7 mins seems very low

what are you guys getting and what pipes-plugs are you runnning? thinking of going to the turbo head for a little more run time

It's not fully broken in yet. It will loosen up when you have around a gallon through it. It will start to bog and get very rich. Retune it and you'll have another minute of runtime.

You will also probably want to run a 7 mm restrictor, and if you are running 30% put in a .1mm head shim. I like the McCoy MC8 better than the RB#6, with the extra head shim and 30%
