Thread: will this part fit ?

(Thanks Series1Buff)

re: Indian SOLEX I have discovered its a relatively easy job to drill and tap a 6mm hole for the vacuum advance fitting on the carby side.. there is a brass plug provided for the fitting .

I read up on the original Lucas dissy specs . On the original 1954 dissy 0n my 2 litre , the mechanical advance doesn't kick in until 1500 revs, so its very necessary to have the vacuum advance working to achieve the zoom aspect from take off.

fix

--------------------------------------------------------------------------The saga continues , but now all sorted. I found the correct location for the vacuum port . You can see where they made a spot for it , in the casting . I carefully drilled a 2mm hole and it came out just above the throttle butterfly ....

The following happens : As the butterfly opens slightly from the idling position, it exposes the vacuum line port to the distributor, pulling the advance around . In the idling situation, the butterfly is closed and the vacuum port isn't exposed and the timing is retarded, this is also important for a static hand crank starting situation , broken fingers e.g.

we put one of these on a 24 garford firetruck (6v) and it eliminates need for 'flasher cans' etc in wiring... runs @ 20 secs as it winds back to centre, during this 'points' in the set open and close (hence the blinking as required!) works up to 12v too

works well, can be mounted through a panel..
