So, a few weeks ago I jetted it down to #24 and took it for a drive. Made it about a mile, and it decided it would idle, but not move without dieing

Called the wife, and had her bring some more fuel line so I could take the Fuel pressure regulator out. After that, it ran just fine for 10 miles.

So, I got home, disconnected the fuel line, and checked the fuel pressure while it idled with the fuel left in the bowls. I was only getting 2.5-3PSI with a brand new pump (!?!?). Doesn't that seem low?

Only thing I can figure is my pump is putting out very little volume, and the added restriction of the FPR was causing it to starve the carb for fuel?

I checked the plugs today. Coloring looked alright on the porcelain. The color on the ground strap was all the way to the base ring. Doesn't that mean I could go one step colder?

So,
Fuel pump having issues with too low of pressure?
Could go one step colder on my plugs?

Thanks for any thoughts,
