Need advice on 216 cu/in timing and carb settings.

Engine has higher compression similar to 235 engine. Carburetor metering rod is 67/46 with a 93 jet.

Car runs at idle a bit rough and fast acceleratiom either kills engine or big bangs in exhaust system.

1. Is there an alternative way to set metering rod without gauge?
2. Which timing adjustment is reccomended due to higher compression?
3. Should original 216 valve adjustment be used or other?
4. Which metering rod and jet is preffered?
5. Is advanced timing reccomended due to high compression and lead free fuel? (This besides the octane adjustment on distributor)

Any advice or info welcome.

Carter produced 128 different type W-1 carburetors, most with different metering jet/metering rod combinations. They also come in several venturi sizes. So the preferred jet/rod combination depends on which W-1 you are using.

Would recommend .006 intake & .016 exh. valve lash. Once the carb is sorted out, timing is adjusted by advancing until spark knock heard under hard acceleration, then retarded to barely audible ...

 

generically higher compression means ignition timing must be retarded to avoid detonation.

Is the spark strong, and rock steady at idle when viewed with a timing light?
Does the idle respond significantly when the idle mix screw is turned in and out?

 

Spark is strong and olmy advancing the timing will result in a little better acceleration. Turning the air or fuel mix screw does not really make acceleration much better.

 

The fuel mix screw ONLY affects the idle mixture ! 1.5 to 2 turns out is the usual setting.

 

Here is mine. I had my carburetion setup custom done by **** York in Franklin, Indiana. The ***sembly arrived (with a dual intake manifold) and for me it was a corectly munt, setup the throttle linkage (I used a Jeep CJ-5 comlltete pedal and cable contol) and then I use an HEI and I used the recommended AC plugs and gaped then wider than recommemnde by .005 I set the timing per the specification for the engine and I use an electric fuel pump with two fuel line filters and after two tries it started. Balancing the carburetors was a snp. I used a Vacuum Gauge to do this. Mine still runs great and I use a T-5 with an open drive line from an S-15 with 3:08 endgears. Everyone tells me the gearing is "Too high." So far I have no complaints BUT if I had to do it over I'd look for a Getz set of 3:30 gears.
