1966 TriPower Exhaust Leak @ Choke Housing Screw Hole
Hi,
I took the Choke Housing off while the engine was idling (checking the choke rod for adjustment) and noticed that I have an exhaust leak out the screw hole. Is this correct or did the metal finally rust away? Is welding a solution (redrill the hole /tap) or do I need a bandaid fix. Thanks in advance. -Don

lol, I know the screw has to go back in ��
I just didnt know if there was a hole to begin with or if the wall belowvthe screw had rusted away. Sovthat means that the choke housing is the only thing keeping the exhaust sealed? I thought that wouldnt be enough! Thanks for the response B-Man & Mr Boneske

A "Blind Hole" would have a tendency to crack at some point. A "Thru Hole" typically will not crack.
Exhaust port "Blind Holes" are different because the head is actually cooled close to the bolt bosses by water. The Poor Heat Riser on the passenger side is shielded from air by the intake runners, (makes it more efficient as a heat source though for the choke), but the thru hole is a desirable engineering machining step for the intake.
