When cold I have to give it a little gas to start. After roughly Two to Three minutes, it idles fine. Tonight I will read more about CIS systems. Any suggestions on things I can check until my gauges show up would be greatly appreciated. Cheers.

I'm no expert, but hopefully Tony and others will chime in.
Yes, you need your fuel pressure tester before you can get any useful info.
Also, I found that a wideband sensor was very helpful to ascertain my AFR.
If it is running poorly (while warming up) you might be able to get an indication of if it is too lean or rich by removing the airbox cover and filter, and then either applying downward or upward pressure to the sensor plate arm. If you lift it, it will add fuel and richen the mixture. If it runs a little better, it might indicate you are running a little lean. If you push down to slightly lean the mixture, and it runs better, then perhaps you are a little rich while warming up.
Either way, you will need to check your pressures as per below...
Definately watch this video and others from this channel.. lots of REALLY good info.
