Dellorto Accelerator Pump Set Up

PostPost by: andyelan » Tue Feb 08, 2011 8:54 pm

Hi Everyone

I wonder if the is anyone here who can please help me with details of the set up proceedure for the Dellorto carburettor accelerator pumps. I know this basically involves stroking the pumps a number of times and then collecting and measuring the amount of fuel flowed. Trouble is nowhere can I find any actual values for this. Failing that can the pumps be set up by measuring and setting the stroke of the pump actuating rods

Thanks very much

I've set mine, but I just used the simplistic method of checking that it will squirt about six feet from the carb.

Hi John

I might be blind but I've looked through both the Plus 2 and Europa manuals and can't see the info anywhere. Any idea what page it's on

Hi Everyone

Thanks very much for the replys. I've actually just done the obvious and phoned Dellorto. Apparantly the answer is:-

20 strokes of the pump should supply 7.5cc of petrol
