Power jet or not?

[jonno]

I have bought a power jet to fit to my dellorto 34mm carb fitted to my tuned TS1 sprinter.But reading the notes on the MB site it says dont fit them to TS1 and RBs,as the feed is too near the top of the float bowl and could possibly let in air.Is this referring to power jet carbs with built in power jets? as the retro fitted ones draw fuel from near the bot of carb bowl.

Probably, the old Amal ones are certainly on the front and with a fair bit of down draft you might just empty the bowl enough.

i think it must be , i run both my Ts`s with power jets , and indeed both are fed from bottom of the float bowl , never had any problems whatsoever

What position do you have your power jet fitted joe? No instructions with kit But I read somewhere on the web its about 2 o'clock position.Course I cant find the info again

sorry for slow reply , mine sits at as you look at it between 1 and 2 o`clock , its on a 30MM PHBH ,if i remember correctly i struggled to get it a 12 o`clock , had the scoot set up on the dyno so no problem with the position , if i can find my camera if post a picture

I'm not sure that it matters much where you fit it into the carb mouth as wherever you fit it the feed will be pointing into the centre of the carb but what I did read was that you don't want to fit it onto a curved section as this will point the feed outwards and it'll be less effective. The deeper you can get it into the carb the better, that might mean building up an area on the curve of the carb [with alloy bond] before you fit it.
