[QUOTE="vibrac, post: 116110, member: 60"] Just fitted a set of 1-1/4 GP 2 to the new twin racer (thats my choice of best inlet size for short circuit) GP2 mean some improvement to steep down draft control and the pilot works like road carbs (on air not petrol) we are retaining the air enricher system (they are not a choke) for checking mixture (in our case on the test brake) as the air flow and carb orifice is not affected by its use Here is a poor picture of the down draft when it was on the Comet with a Gardener yellow lines are UFM and red line the CL of the carb it will also explain why our tank has a big hole in the top! That was a source of puzzlement to many at Cadwell in the autumn when our race winning twin was on standard monoblocks o_O [ATTACH type="full"]32246[/ATTACH] [/QUOTE]
