Nikki Carby On A 4k

[projectKE10]

I noticed that there is a section in the knowledge base about putting a nikki carby on a K series.

I put one on my 4K about a year ago, put a full kit through it including needle and seat, it went fine but there was a problem, the bowl kept overflowing on idol and flooding the engine and it would stall.

Now i spent ages racking my brain trying to figure out the problem, I thought it was the float level (but you know what thought did!,) I lost count of how many times i pulled the thing appart to adjust it, I was nearly ready to through it over my shoulder and try something diferent, (I remember saying to myself, "f'n Holden s#@t.) Then it hit me... too much fuel pressure, the Nikki doesn't like the full pressure that the 4K fuel pump gives it (I'm gessing the gemini fuel pumps didn't have as much pressure.)

So I got me a Holley fuel pressure regulator ($85approx) and there you have it problem solved.

 

Hope this is usefull, has anyone had this problem?

Might be worth adding to the knowledge base, i dunno.
