I tried the traxxas plug (supposed to be the proper heat range), put some
other fuel in the tank (old fuel) and leaned out the low speed needle a
little. the high speed needle is 1/4 turn leaner than factory settings.
It looks like the fuel is having a hard time getting to the carb even with
a priming. hoses look like they're in good condition. I also bumped the engine
over with my finger on the flywheel. feels like it still takes a bit to roll it past
top dead centre.
