Well ol' 1343 failed the emissions test with very high HC and CO. Took it to a
carb specialist and they said I need a new carb. It's running too rich but
they couldn't lean it out enough without the engine dying. The carb is
apparently dumping fuel at partial throttle (they test at 15 & 25 mph). Was
told this is a common problem with Holley?
I know it's been discussed before but what carb should I put on? It's got a
Holley 500 cfm right now (don't know which model). Should I stay with a Holley
or go back to Ford?
The other issue is that the engine is from a '73 Montego so it doesn't have the
smog pump but it has always passed emissions before. Because of that, should I
go with a '73 or '75 carb?
