Running twin OX66 250's on my contender and I've notice the last several trips one is consuming more fuel than the other,8-9 gals. Motor has been running great when throttled up but at idle is rough. Any thoughts/ideas where to start?

you can easily monitor fuel pressures/vacuum to see if you have restrictions instead of just replacing filters.
Fuel LP pumps can be unbolted from motor and pump primer to see if it is leaking fuel out pulse port
O2 sensors maybe a little harder to check out along with the injectors

Went home yesterday and started by pulling plugs.....last to come out was fouled with 'blue emulsion'.....pulled the head and found the head gasket has been leaking into the cylinder.....checked the cylinder walls and everything looks good...new gasket and plugs today.....we'll see what happens....thanks to all for the insight and suggestions will update after test run
