pilot jet on 25mm PHBL

[bluebob]

I am rebuilding a 25mm phbl carb which I stripped some while ago.can somebody tell me if the pilot jet simply screws into the carb body.Or does it go into some kind of emulsifier which I may of lost.Hope I am wrong but I feel something is missing.(and the dellorto diagrams don't help).Does anyone know please?

Straight into the body the emulsion tube is on the VHSH type carbs

PHBL usually have a surge washer that fits onto the ali bit that the jet screws into.not sure if it`s actually needed ,but then why did Delorto fit it ?

thanks Martyn.will look into that.the carb was put back on scooter early august and runs ok,but anything that improves it is worth trying.

I was told it was fitted to stop surges on scramblers and dirt bike, mine seems to run well without it.
