Hey Chris, I wanted to check your plate specs. It's number 134-39. The "39" would be stamped on it.......Anyway, it has a jet orifice of .073. That's the equivalent of a #70 jet. Your still a little oversquare on the secd side so I don't think you need to jet up for that specific reason.
It's nice to have the convenience of a jetable plate or block, but I think i'd drive it a while and keep a occasional check on the plugs to see how there coloring. I'm not sure you'd gain alot, unless you hammering on it constantly......lol. I should add, make sure your float levels are just at the weeping point on the site holes.
I'd still play with the secd springs a little and see if you can detect any improvement.
