Dellorto advice
Posted: Sat Oct 04, 2014 4:38 pm
I'm new to my Plus 2 and also to Dellortos.
My car has been laid up for 7 years or so and has only recently been returned to the road. Having had a lot of bother with crud in the fuel line, I now find that I seem to be running on only 1 carb (i.e.2 cylinders) - not good.
I have DHLA 45s fitted, and whilst idling, my front carb (the apparent non-functioning one), dribbles a steady stream of fuel into the venturis (both barrels). A puddle forms in the choke and clearly the front 2 cylinders are running so rich that the plugs foul up and no combustion takes place.
Needle valves seem to have black rubber tips and small springs, and from what I can see seem to be functioning ok (though it's hard to tell)
I'm guessing that it would be wise anyway to rebuild both carbs with new seals, needle valves etc. I have read that this is sometimes symptomatic of corrosion in the bodies, but I can see no evidence to suggest that this is the case here.
Is there anything else that I should be checking?
Thanks in advance
Simon
