Weber DMTL Jetting
Just following up on previous post.
Primary Secondary
Venturi ( choke) 24 25
Auxiliary Venturi 4.0 4.0
Main Jet 120 125
air correction jet 155 155
Emulsion Tube F 30 F 25
Idle jet 55 60
Idle air jet standard standard
Pump jet 45 n/a
Pump bleed standard
needle valve 175
starter jet n/a
float level
it all gets squashed up in the post but the first number is primary and second is secondary.
Adapter plate can be bought but easy enough to make from 10 mm aluminium,
this set up bolted on, idled and ran with no stumbling, flat spots.
Very lucky as it was a new carb.
Have yet to try it at motorway speeds.
1800 would need variation of this.
I found the jetting info hard to find, hope this helps.
cheers
John
