Exactly as your b310 carburetor my one has vacuum lines working but slow jet and electric choke not working, when idling its not smooth rpm increases and decreases all of sudden and idle also too rough. And fuel also burning when adjusting the mixture screw to just one round from full tight make this happen. 🙄🙄🙄 replaced the petrol jet to 85 but vehicle is hesitated to accelerate, now it has 90 sized one installed,
nowadays can’t drive the vehicle as it jerks while on move and suddenly engine dies too.
If there any trusted place that you know to purchase a good reconditioned carb is very useful!
thank you!
