....................back on the case

[geoff]

well, not that it is a good thing, but being confined to our home and with our b&b business closed, I now have time to spend on my hobbies - one of which is my Velo. Not run since I last posted here - and then not running well.

I am back on trying to get it to run nicely. I can get it to start but not tickover, so as previously, I ask the following question;

I want to set up the carb so if I start with the two adjustment screws fully clockwise, can anyone suggest a good starting point; like for example, each one two complete turns anticlockwise or some other "rule of thumb" commencement point?

Regards to all

This has basic tuning on a Dellorto carb. ducatipaddy.com/Dellorto%20tuning%20guide.pdf

thanks for that, I'll take a look.
I had another look today and noticed that fuel is leaking out from the knurled adjuster. I am wondering if perhaps there is some problem with the float. I have checked that the float does cut off the supply - and it does - but perhaps it is maladjusted?
Was not a good day today - I finally got the machine running and kept it running using the throttle - and guess what - smoke eminating from the voltage regulator !
This is now completely fried. Never a problem with it before so I have no idea what has happened here.
Like I said, not much advance today !

Jeffy, that link is excellent, thanks. I now need to find a new replacement rubber seal for the float chamber.
Any ideas for a source?
cheers

Geoff, try this if it's a little closer to home for you;

Some of the exploded drawings imply that the gasket could be purchased separately - though it's good practice to get a full gasket set for the carb unit.

thanks Phil, I have ordered a set from delorto now because the seal for the float chamber is not available alone.
