TQ questions

I would not use any TQ that has white corrosion on the outside.....because it will most likely have corrosion in internal passages that cannot be seen or accessed....causing 'weird' problems in operation.

I would use the 98XX.

The 9080 might be off a BB Ford. 9085, 9071 were used on Aussie Fords. These carbs were also used on Inter trucks.
9080 had 098 pri jets, 137 sec jets, 2179 rods 074/066/042
