Here you have some more: http://www.allstyles-scooters.com/acata ... tml#a58992 Not sure if they stock all of them.

Anyone know the difference between 1, 2 and 4?
And the difference to the only one delorto makes?

Harry Barlow at Pro-Porting in Leicester sells modified main jets and atomisers for 22mm Dellorto/Jetex - he does the modifications himself.

Well, i Tried to up the main. Realised that something is probably blocking my tries. I'm on 162 main and it still doesn't 4stroke.

Will have to source an drilled automizer.

The plug looks a lot better though!

The only way you should need to modify the atomiser is if you're using a 150 atomiser and slide. Fit 200 atomiser and a 200 slide and I reckon you'll find you can run a 125 or so main with good results.

A Jetex fitted with 150 slide and atomiser will just manage a 200 std engine on a 135 main jet as the atomiser restricts the flow.
