I'm running 54's now.

I'll also measure the PVCR holes. I think my caliper can do it.

I'm puffing smoke at full throttle and she smells. The plugs are also very wet. That's why I'm thinking the jets are too big.

I'll try the 49's that came in last night, run it a mile or two, and read the plugs again. I can clean them off with some carb cleaner in between.

I'm also running E3 plugs so I can't read the spark as well as I could if I were using regular plugs. I might pick up a cheap set of regular ones just to better read it then swap the E3's back in. The E3's do help it, though. The idle went from choppy to smooth with them when I swapped them in a year ago. Old plugs were new-ish too.

I have a plethora of power valves. When I set the vacuum screws I'll re-size it then.

Also considering changing the secondary spring to a lighter one.

I'll warm it up, before doing anything, and look into the carb while its running to see if my squirter is dumping fuel. That might be the case.

Probably do all this tomorrow morning. I'm sure my hung over neighbors will enjoy the Flowmaster 44 revving at 9 am...
