Non bleed versus bleed type pilot jets

[1fasteffjay]

What is the difference in performance between a bleed type pilot jet and a non-bleed type? My '86 had non-bleed type installed in it but I see that rpm sells the bleed type pilot jets.


Thanks!

No difference. The FJ carbs draw the fuel through the bottom of the jet where others carbs draw through the side of the jet.

The bleed type seem to not clog so easily.

  The jets ??
I wondered about the two types of those pilot jets. I have read somewhere that the bleed type is usually found in carbs for two stroke application. The two stroke having a somewhat weaker vacuum
signal available to the pilot circuit. The extra holes provide  more bleed air to enhance emulsification.
The FJ carbs have no air bleed connected to that area of the jet. Ergo, the holes make no difference .     Randy , ,looking at the pictures , in either type of jet. the actual metering orifice is located in the tapered end. Fuel certainly enters through the slotted end to be drawn through the metered end. I think that if fuel was, as you say, in some cases drawn through those side holes , the jet would not be metering the fuel.  I'm  inclined to think that the bleed holes are incoming bleed air only.
