BJ8, What is the purpose of the vent pipe hose to air cleaner?
What problems could it create?
I'm helping a friend get his newly acquired 66 BJ8 sorted out.
He had a British Mechanic go though the car, full tune up.
We took it for a ride yesterday to find it back fired, and chugged somewhat.
On the ride back to my house, we pulled over. I found the vent pipe hose was not connected. I attached it, we finished the ride home. No change in performance.
He leaves my house, 10 minutes later come back, car runs worse with the vent pipe hose attached.
So I suggested we leave the vent hose off and I'll look into it with help from the BCF guys.
Before he drove off, I said let me poke around a little and see if anything else is disconnected out of adjustment.
I found 3 items. Low dashed fluid, vent pipe hose was not attached and one of the choke cables was not adjusted correctly.
I took the rear air cleaner off and found no oil in it.
I took both dash pods off to find both carbs were black with a little oil on the bottom rim where the pod meets the carb. I cleaned that area, wiped down the inside to the dash pods and carbs. Put carbs back together, added dash pot oil.
Adjusted the choke cables and confirmed both were working properly. (Mechanic said the choke was not working and worked on it. Sorry guy, I had to redo your work, cable and spring)
Owner left (without the vent pipe attached) once home said it now runs better then how he got it from the mechanic.
Owner will run the car later with the vent pipe hose on to see if there's any difference.
What is the purpose of that hose and how can it affect running performance?
