Spent some more time messing with the Tune Up, trying to figure out WHY it would not idle or run smooth. Talking with my friends on the VCCA decided to look for vacuum leaks. Using an old timer trick broke out a can of carb cleaner and spray small burst around intake manifold, nothing. That is a sign of relief, then did a few small burst around the carb gasket, and there it was. has a leak all around the gasket. so now need to remove the carb and replace the gasket...
All for another night
Decided to pull the Carb to check the Accelerator Pump since I have to replace the gasket. Looked inside the throat and it was black !! coated !! did a little checking and pulled the bowl, full of fuel, float was at about 3/4" as Spec'd. Tinkered with the Acc pump, it was REALLY LOSE to the point that when I removed the Nut & Washer off the bolt and removed it, the Level for the Acc Pump DROPPED to the bottom. In fact with NO effort I was able to remove Acc Pump Level from the pump. It was BONE Dry !! the Acc Pump looks like it has NOT seen Fuel in YEARS !! I removed the bottom screw from the Acc pump and dry as can be.
Sprayed some Carb Cleaner up in the Tube and it went right back out at me. So there is a Clog in there somewhere. Checked out the other jets & ports, they look good. After a few minutes of the cleaner, I sprayed another burst in the acc pump port and out it came thru the jet in the throat.
So looks like it really need a GOOD CLEANING maybe a Rebuild w/ new gaskets and such.
Decided to clean it up best I could and call it a night
Ok, today after cleaning the carb, I put it back together and hooked the Vacuum Gauge to the Manifold where the Wiper Vacuum Connects.
In doing so I got right about 19-20 Hg on the Gauge
...it seemed to stay steady there
If I rev up the engine should the reading drop, climb or just stay steady ?? This is during Engine Rev, figure it should even back out once at a Steady RPM.
Did a compression check as well to be on the safe side.
I am getting approx. 75 PSI on all 6 cylinders !! so that makes me feel a little better.
Going through my stuff I have for my 1929, I have a spare Carter RJH-08 150S, currently have the Carter RJH-08 136S on the car.
From my understanding this may be an NOS Carb ??
Looking it over there are NO marks from it ever being mounted, Mounting Flange is Clean & can still see machine marks in it. On the back side of the Flange you can NOT see any scratches or surface wear from a bolt or nut or a washer being against it. All the Springs look Pretty Original as well as the Screws, Thread are perfect and no signs of wear. All the tabs and Brackets are still in shape and show no distortion. The Brass bowl looks GREAT, other then tarnish/ coloration from age, shows NO marks from wrenching, banging or anything. Nut looks NEW. Also still ahs the little ? Copper/ Brass ? tag in tack, stamped with 2 shapes/ holes and marked with a J 8 and then a small 8, anyone know what these means ?? Also looks like a Lightly stamped "1" then a BOLD Stamped "50" lightly stamped "S"
Looking in the intake/ Throat it looks clean, can still see the cast surface finish, as well as the acc jet in the back. this thing shows NO sign of wear... did they test these things at the factory before installation/ shipping or just build and ship and let the guys in the field/ factory install and adjust/ test/ tune.
Shot some pictures up and thought I would share and get feedback from those that my have some input or thoughts.
If it is possible I may put the 150S on the car and have the 136S rebuilt and store for a spare, or just sell it to a new home. If not possible I will rebuild the 136s and put it back on the car and sell off this 150S.
Great car !
