RE: Top end response

[Rich Kinsley <rlkinsley@xxxxxxxxx>]

Do you mean as in floating the valves? I've done that on other engines 
before and this is not like that. It feels more like when a fuel pump 
fails and only allows a small amount of fuel to flow. I had a truck that 
had that issue and I could run it but it'd only do max of 25mph, period.
