We have a stoxck 1947 Mercury, with a Fenton intake and dual stromberg 97's. Carbs have been rebuilt recently. Carbs have been balanced with the Unisys system. Both carbs have been COlor tuned with Gunson's Color
tune. Car was running great. Now it starts bogging when we go over 45 mph. I check fuel filter, fuel regulator is set for 2 1/2, sparkplugs are clean and gapped at .25.
It seems to get worse with the heat. We have been having 95 degree weather lately.
First and second gear runs smoothly, 3 rd runs smooth until 45 mph.
Any suggestions would be appreciated. Something that I am overlooking?

Thanks,
Bob- Hampshire, Illinois
