Here is a plug I pulled out today. I am running a 65 power valve and it had 64 jets in it, I could not find 66s so I put a set of 67 I had in it. It didn't seem to want to idle below about 1500, I began to adjust the float levels as they were high and the clear plugs broke after a few minutes of running, they were only finger tight against the o-rings. At that point I had to let it cool down in order to take the carbs back apart and get the plastic pieces out. I'll start back on it tomorrow, I have a set of 65s I will probably put in. Once I get it all back together tomorrow I will start with the timing and bump it up. What is the best way to set it by vacuum gauge or by ear. I have always been very successful by ear. I was in the process of getting it running well again so I could go through Tom's set up from start to finish.
