74 2.0 with Dellorto 36 duals has been running fine since I pulled it out of storage, got in it to run pick up a pizza the other day and it seemed to lack power, tonight I took the air filters off and turned on the fuel pump, holy crap the left front carb barrel started filling up with fuel! The rear barrel seemed fine, just the left front barrel??? Any ideas, I have pulled the carb and it looks okay, the only odd thin is the large spring under the brass nut is kind of gunked up. I'll go snap a pic.
These were purchased rebuilt from the guy in Italy, they ran fine all last year. |

Check the seat for needle valve in the bowl, make sure no crud has built up on it. If the needle valve doesn't close, fuel will keep flowing into the bowl even once the float is at its highest position and will then dump into the barrel. Interesting it is just one barrel but maybe you were on an incline when you were checking. While you are at it, reset the float height as per the dell manual. A little tweak on the float stops may be all you need to shut the needle valve properly (if that is the problem).
That large spring is for a choke mechanism for an alfa, you aren't using it. My understanding is that as long as that spring is in there, it shuts off the choke circuit so you don't have to worry about it. -Chris |
