I'm rarely disappointed in that assessment; although it does happen now 'n' then.

Add in the lack of vacuum advance, cold heat-range plugs, and lack of fully warming-up the engine, and this is a "perfect storm" for plug fouling. All we're missing is a 160 thermostat (or even worse--no thermostat.)

Perfect storm for fuel-fouled oil, too.

Everytime I see a "cold start" video with a carb without a choke ..sit there and Idle I just shake my head...it's too rich! It shouldn't just start and idle!
