Great looking engine Bruce! I have that flat spot but I'm just too power hungry to go to the smaller ventures. My idle jets are 60s which are what Pat put in when he dynoed it before shipping it to me. This is weird because we are at 1200 ft of elevation and I should be running smaller jets than you sea level guys. A very knowledgeable VW guy here told me if your idle is set right when your mixture screws are 1 1/4 to 1 1/2 turns out, your idle jets are right. Right now the screws are out about 1 1/2 so I don't know what else to do other than drive it and enjoy it and forget about the flat spot. Would richening up the accelerator pump help?
