need help with my 25 DB carb

Recommended Posts

Has it always been like that or changed recently.  If always, then the mixture position probably just needs adjusting.  If recent then could be fuel starvation, blockage or sticky/faulty float?

Has the car not been started for a while?  If so, it could be something is gummed up.  If the dash pot is stuck I believe it could cause a problem like this.  A vacuum leak can also cause this symptom.  This cross section shows the dash pot and is from Dyke's Automobile and Gasoline Engine Encyclopedia.  I found it on Google and was able to download a copy.  Lots of good general troubleshooting info in there.  Do you have a copy of the DB Mechanic' Instruction Manual?  I often see reprints available on Ebay for not much money.  Have you searched this forum?
