Jetting question, Plaese help. 1.8l type 4

Please help me with getting the right jets:

I am running dual weber 40 IDFs. They came with the following jets/setup:

air correction 2.00, Emulsion tube F-11, main jet 1.15, pump jet 0.50, idle jet 0.50, venturii 28mm

We ran the engine for a few minutes yesterday, but it got quite hot and sounded like it was running with too much air (popping)....

The engine spec is:

1.8l type 4

93MM Pistons (Porsche 914, domed to increase compression)

66mm stroke crank

308 degree webcam, (valve lift: 0.507, duration at 0.050: 272 degrees, Grind no. 86c)

polished + mildly ported type 4 heads

Stock rockers

Bosch 009 Distributor (Standard points)

THe car is a full weight 1972 Beetle running a 1500 gearbox.

Can anyone help me get the right Jets?
