what does the gurtner jet do?

hi what does the gurter jet do to the jetting on a dellorto 21mm carb tryed researching couldnt find anything ?

 

i no about main and pilot jetting just nothing on the 3rd one

 

You've confused me. Gurtner is another make of carburettor, just like Dellorto or Mikuni. Can you take a picture of the part you are talking about, so that we can work out what you want to do?

 

Possibly, if the carb takes 6mm jets, although I thought that Dellortos took 5mm jets.

 

lol my bad peeps i mean the third jet in the carb bowl between the main and pilot jet thought it was called gurtner jet as it looks the same as this http://www.pedparts.co.uk/product/710/single-gurtner-jets ? i have stage 6 dellorto 21mm

 

will post a photo later

 

dw people just found out its a choke jet
