Re: Mopar 2 bbl jets
 

I bought a nice jet drill set from S and K Speed back around 73, it has .038 to .110" bits. I use a very small battery powered slow speed drill and let the bit pull itself through, I use an old carb to hold the jet. The results are excellent as seen through a magnifying glass.

If you use Holley jets and they are too long, get some model air plane glow plug washers (soft copper) to space the jet. Glow plugs have 1/4 - 32 NF threads just like the Holley jets. Best source for the washers is the R/C flying field, just ask, most modelers have extras.


If you drill old jets try reaming them to final size with proper lubricant for the base material. This should help you get some repeatability on size. The better your set up the better the results.
