Autolite 1100 Carb jetting

[Anonymous]

I need some advise. In my effort to get more performance out of the Autolite 1100 on my 66 200. I discovered that the main jet size is a 60f or (.060). I have read articles on how to get small improvements out of the poor carb set-up. In the aticles it shows 11hp improvement and recommends larger jet ( .065 ) to (.067 ). WHERE CAN I pruchase these Jets. All I see in the market are JETs for Holley Carbs. Will they fit? They appear to be about the same.

Unless your engine is running lean, going to a larger jet will not increase your power.

New parts are no longer available for the Autolite 1100. Your best bet is to hit the salvage yard or swap meet to scavange jets and other parts. Pony Carb may have jets to. They recently move to Las Cruces, NM.

Autolite jets are different than Holley and Carter, so they are not interchangeable. Damm!

Check your plugs for Air/Fuel ratio conditions. If plugs are closer to white, you could be on the lean side. If they are tan (perfect) or shade of darker brown ore black, you could have a rich condition, in which case you'd benefit from a smaller plug. Elevation, plug heat range and engine condition are big factors in plug reading. To get a try reading, warm up the engine, then install a new set of plugs (no choke), take a drive at highway speeds for about 40 to 60 miles. Pull over, with minimum idling and pull the plugs for a color check. If the engine is burning oil to any degree this will not work.

Thanks CZLN6,

I spoke with JT with Ponycarbs in Las Cruses Nm. They were able to find a jet for my carb. I asked for a 62F (.062) since I'm above 5,000 feet in elevation. I found an original service manual from Ford and it had spec. pages on the jet issue. All of the Autolite 1100 range in Jet size from 59 to 67 pending on man. or auto trans and elevation. I will post the results as soon as possible. Thanks again.....PE2

HOwdy back:

Please do yourself a favor and do a simple before-and-after performance check, by timing your cars acceleration, say from 30 mph to 60 mph. Also read your plugs. If there is a change it will be too small to tell with the seat-of-the-pants dyno.

At 6,000 ft elevations, I'd guess that you need to lean out your main jet. At elevation increases, air gets thinner- less O2. That means that your Air/fuel ratio will get richer- not good for economy or performance. If you need to rejet at all, my guess would be that you would need a smaller jet to increase performance.

At that elevation, you can benefit from some additional initial advance and CR too.

Adios, David

Keep us posted.
