Been running AFB's for a long time but have never seen this and my carb guy who built these seems to have either moved or permanently left the physical realm. Older gentlemen from New Mexico so you never know.
Anyway .. was doing some tuning on the 496 / 6-71 Moonham blower / Cater AFB 750 Comps built for blowers, and had ordered some new metering rod springs in preparation for some fine tuning.
Pulled the metering rod caps to compare how far they where being pulled down while watching my vacuum gauge and to my shock... There are no springs pistons or metering rods there.
Now being these are the 750's which are known to have a lean spot issue I am wondering if this was done on purpose and had seen a post long ago where some people actually pull them out completely on blower setups.
Anyone seen this before?
They run ok just seem a bit rich on the idle side. Also these are not new untested carbs I ran them on my 427 with a blower just never got into any fine tuning before I pulled everything. It's also easy to fix if needed.
thanks
Mike
