Starts runs but won't accelerate

Just wondering if anyone has any more Ideas on my instant boging when tapping throttle, fuel psi 38 to 45 holds when shut off. Check out my info on prior threds if you can, thanks for any help, George.

Checked timing it was at 12- 13 deg. base not to far out from 10 and did advance to aprox 38 at 3500rpm. When I went to check timing high idle came on ok but just as iac. valve kicked out to drop idle cooling fan came on guage showing cool still not hot enough for fan yet looks like this is going to be a fun one.
