Each 454 on my 3807 has Rochester carburetors. This is the interesting part. They have divorced chokes. Meaning they have a separate metal coil mounted to the manifold that is attached to the choke plate. When engines start choke is fully closed. When the manifold heats up, coil expands, lifts the rod and the choke plate opens. Seems cave mannish, but maybe it was a tried and true method in 88?. Just had the carbs cleaned and rebuilt. Still have the issue of when started, there’s a smell of raw gas, a little blue smoke in the exhaust and a bit of sheen can be seen. Engines start and run well, just very rich and I guess take a while before the choke opens. Is there something I should do? Is it any big deal that they run rich for a bit? I think the adjustment is to bend the rod so the choke plate is not so closed. Here is a pic of the choke thermostat. Any thoughts would be great. Just not sure if this is normal or an issue I should look at.
Thanks,
Vic
