Failed emissions for high hydrocarbons
I have a 65 f100 352 with autolite 2100 carb. NJ emissions test found hydrocarbons to be 3800ppm where as the spec is 1400ppm. My question is what can I do to get the most bang for my buck in reducing Hydrocarbons? So far I have rebuilt the carb and I plan on setting the timing, tuning the carb and changing the plugs and air filter. Is there anything else I should look at?

Choke working OK?
Float level correct?
Idle screws slightly lean?
Power valve correct and functional?
Jet sizes correct? Try going down a size.
Hitting on all cylinders? Nothing dumps HC like a missing cylinder.
Stock ignition? Consider pointless HEI. Stronger spark, less fooling with it.
NJ is crazy to try to smog stuff that old. Not even nutcase California does that.
FWIW, my smog checks show 0 to 4 ppm HC tested for some '95-'01 cars/suvs we had/have.
3800? Holy smokes!

I may be nuts here but I do not belive that there are any federal laws on trucks untill about 72. California on 68 half tons.
You may want to appeal this as it is pre smog and generaly not goverend by such rules.
Most states grandfathered vehicles in from that era and recognize other states grandfather laws on such issues. So, if it was originaly sold in another state it should still be exempt. I would realy look into this as they may try to railroad you. I dont think there are any smog laws on any vehicles for 65 nationwide.

E85 sounded good until we started talking about the rubber and plastic that will dissolve....

Since your dad is prolly not the original owner, some/all of the emissions related parts may have been removed before he acquired it.

Does it have a road draft tube? If not, it has or had smog equipment.

All 1961 and newer vehicles (Ford/GM, whatever) that were sold new in CA were required by CA law to have a PCV valve.
I'm pretty sure that all 1973 and newer vehicles sold new in CA had an EGR valve (which was introduced in 1973). Some trucks were not required to have Thermactor Emission-smog pump as it depended on the GVW.
Ditto for the Evaporative Emission system first installed in 1970 Passenger Cars, F100's, Bronco's and E100's.
