Pilot jet query

<< < (2/3) > >>

K2-K6:
Of the jets,  your original looks to match the "trigger" supplied one.

Just that the "trigger" jet takes fuel from lower in the float bowls,  perhaps they were changed to make them less susceptible to any lowered/impaired float level discrepancy to give more reliable slow jet metering.  They look like they do the same thing though, assuming the clearance in your float bowl is ok.

The third example doesn't look like it will fit at tall.

deltarider:
The one Trigger has sent you, is the correct one.

You are correct Ken. Gordy has pods fitted though, so some change would have been made to jetting to accommodate the pods.

Gordy Crazyjambo:
Sorry folks, yes should have said. 40s due to custom pods and as it idled/ran well enough low dow etc I'd like to retain them.

Delta rider. I wouldnt doubt Trigger for a second 😉

K2-K6  interesting, thanks. Hadn't thought of it like that at all. I have a spare trigger one arriving tomorrow from david silver. I'll maybe use them in the two central carbs so not just one is different albeit same ish👍

Bryanj:
If they are non standard chances are they are aftermarket so could well be a different design that the suppliers insist will work exactly the same!!
