As stated above, car gets weak at 5600 and is flat at 5800. Air/ fuel ratio will go to 10.1 to 1 if you stay in it. A fast mechanical "type" sound can be heard above 5600 but no popping or back fire so i'm thinking the valves are floating right, well i had (2) springs checked today, results are 150# closed...350# open,which is what RED, Dave Weber, and Tom at Champion all said should be good enough to stop floating. So now i'm looking for more idea's....TIA......Greg Crabtree
