Re: '70 K20 carb options

new carb riser and gaskets, new intake manifold gasket on.
was able to the get the intake back on with the disty in the right place and buttoned everything else up.
It took about 5 minutes worth of cranking to get it fired up and it died almost instantly and backfired a couple of time.

Once it was able to get it running, and stay running it was at 2k while i filled up the radiator. I hopped in and hit the gas pedal to 'kick it down' and it went to about 800 RPM's, and sat there. I put it in gear (granny gear) and slowly let off the clutch to see if I can get it rolling, almost died so I gave more gas...and it killed it.

tried getting it running a few more times, and it always starts out at around 2K rpm's, and when i give it gas it dies.

I am thinking I need a new carb. or to rebuild this one (which I am not sure about doing). It seems as though the automatic choke is the problem, maybe at start up.

what would you choose? New carb? Rebuild kit and just change the automatic choke? Or??
