FWIW, after I finished my engine, I wasn't able to harness all of the power until I invested in a CIS gauge set for testing my cold/warm/enrichment WUR fuel pressures.
My condition was overly rich and the car just wouldn't rev past 5,500 before chocking on gas. I had the Imagine Auto fuel head, but no amount of adjusting at the fuel metering plate would lean it out. Thus I made my WUR adjustable and the engine just came to life!!! Revs to my limit of 6,500 effortlessly!
