I have a 0-360 with 90 hrs on rebuild. Ran some what smooth until I installed the carb kit for the ma4-5 that fattens up the top end. Now the engine runs like a dream. But... I now notice a loopy idle until it has completely warmed up.
I have tried to lean the mixture but showed no positive results. The engine smooths out above 1500rpm. No change with a mag check. Checked for a leaky lifter and inspected the valve springs. It idles kind of like a big block with a big cam. Anything else I could check?
