Which jets?!

[bendyminge]

Evening gang, I've been given some jetting advice for a PHBH 30, and everything was easy enough to follow apart from these two;

Tickover 45-48
Float – Needle valve seat, jet 250

I've no idea which these two are and I'm scouring the Dellorto website and can't see anything that matches these descriptions. Any ideas welcome!

Further to that, "float – Needle valve seat, jet 250" was, as a rule of thumb, double the main jet value.....if that helps identify the bits at all?

The needle valve jet is the one into which the float needle fits. 250 - 300 is usually recommended. It controls the flow of petrol into the float bowl.

The other one you mention is more usually called the slow running or pilot jet.

Ace, thanks for that. Good (cheap) website too for Dellorto bits.

I'm new to all this, so we'll see! Running it with a Gori GP50 on a Muggy 198. Thanks again.

Yes very good value for genuine Dellorto carb parts. Don't seem to add LAT.
