CARBURETION |
|
Carburetor |
Carter - No. 150-S, Single barrel updraft
Idle Adjustment - 5/8 to 1 1/4 turns open; idle at 6 MPH, adjust in to make rich; Well Jet
assembly - standard drill size 56 #(a)
Adjusts fuel flow up to approximately 18 mph.

Float |
Float Level - 3/4" measured from machined
surface to top of float (while held upside-down) #(a) |
Accelerator Pump |
Set plunger pin in hole marked "W" in
pump arm to give longest stroke for cold weather. Set pin in hole giving
shorter stroke for hot weather driving. #(a)
"W" setting in pump arm for winter, "S" setting for summer, and
"Center" setting for average conditions #(f) |
IGNITION |
|
Coil |
Delco-Remy No 526-B #(a) |
Bracket |
Mounting Bracket DR No. 1842364 #(a)
The original coil and bracket were all one unit. The bracket was tack welded to the
coil and it was not removable. The bracket listed above is for a later type of Delco-Remy
coil which had a removable bracket. This type of coil and bracket was a retrofit for
1931. #(f) |
Distributor |
Delco-Remy No. 633G, Firing Order 1-5-3-6-2-4 #(a)
Points Gap .018" to .024". |
Spark Plugs |
AC type G-12, Size 18mm, Gap .024" #(a)
The gap of .024" actually is the wrong gap for the 194 engine, especially when using
the modern AC-C86 plugs. At .024" gap the car will "pop" out the tail
pipe at idle, however when the modern plugs are gapped to .040" the car idles
smoothly with no popping, and the overall power is increased dramatically. The same
thing happens when the gap on the original AC-G12 plugs is increased. When the spark
plug gap is increased from .024" to .040", the timing should also be increased
from the factory 12 degrees to about 18 degrees. There is no 18 degree timing mark
on the flywheel, so the 18 degrees is approximately when the 12 degree mark is just ready
to disappear out of the timing hole on the advanced side. Setting the timing here
will also help to increase the power. If the engine "pings" at this
setting, then the distributor should be retarded slightly until the "pinging"
goes away. #(f) |
Ignition Timing |
12 degrees BTDC ("UC" on the flywheel
means "Upper Center" but it is equivalent to TDC) #(f)
A more recent opinion is to increase the spark plug gap to .035 or .040"
and increase the timing to 18 degrees. See
here. |
Lock |
Briggs & Stratton, Series C1501-1700, Key

VALVES |

adjust Intake = .006", Exhaust = .008" #(a) |
Timing |
Inlet valves open 4" after top dead center.
The flywheel is marked for No. 1 cylinder. #(a) |
Valve Springs |
New design with variable pitch between coils.
Open pressure 80 lbs, closed pressure 44 lbs. #(b) |
HEAD |
|
Head Bolts |
Proper torque for the head bolts on a 1932
Chevrolet is 75 pounds. Be careful on original bolts however, because you could snap them
off due to their age! #(f) |
