[DeTomaso] new carburetor starting problem, need help

when i start it in runs up to 3 k rpm within a few seconds so i turn it off, i guess it would redline?

how do I have time to spray when it over revs so quickly?

I read about that spay for leaks tests  but should I let it rev that high on startup?  If I knew it would stop at 3 or 4 k I guess that would be ok as a test. 

Wouldnt I have to have a massive vac leak to cause car to over rev on start up?

Thanks
Clay
