New motor bad carb
#1
Well finally got the motor rebuilt after the `Blowing by Exhaust smoke`post earlier.

Started up fine not too loose not too tight, sounds good, running rich though, progressivly worstening, then a massive peak in engine vacc.then stop..
checked mixture,float,pump clearance all good. Began to have horrible thoughts about the inlet manifoldDuhMaybe the distibuters given up, IVE got a new mallory Ill try that.
All plugs are soaked and Im stressing, Still wont go, though mallory ss is firing as it should, firing orders been checked 50 timesCrazy

It runs a holley avenger 670 so decided it must be the infamous power valve, opened it up and found this brown clay like stuff everywhere and the metering block was crumbling apart.
Went online and saw this has happened to others, rang to Holley and gave them the codes, they were really helpful and explained there was a limited batch of poor metal castings that have been recalled. Just have to send it in for verification and they will send me a new carb( not bad huhThumbup
