Reinstalled exhaust, intake and carbs on BJ8 engine. Adjusted carbs per directions but cannot get idle down below about 1300. It seems that the linkage hits on the metal of the heat shield. see photos, the carb coupling shaft with the bent piece of metal that hits heat shield. Should the heat shield be grooved to let it pass lower.

One point is that your missing a small elongated washer that goes under the adjacent bolt and provides a shoulder to stop against. The metal shield looks right but there may be other issues.

Hi Randy,

John is correct. Here is a picture that may help. I know it may be difficult to see but the throttle stop rests on a platform that mounts under a bolt on the manifold. It looks like your stop is using the heat shield as the resting platform without the proper component. If the platform is in place, you will need to reposition your linkage and will have the proper heatshield clearance.

On last think, I have owned my BJ8 since new and have never been able to get the low RPM idle indicated in the book. However, I have found an idle of between 800 RPMs and 1,000 RPMs allows my engine to perform nicely.

Hope this helps,
Ray(64BJ8P1)

Thanks John and Ray, When I looked at the heat shield it looked somewhat deformed(bent) that is why I was not sure what was going on there. I am printing out photo so that I can locate what is missing.
