So, I reassembled a Cen GX1 from 4 years ago, hasnt been run since then. Cleaned out the carb, built the car. Attatched the glo-starter and with one short pull the engine fired up and idled. I was in shock.. I was expecting to have a sore arm by the end of the day.. but no. One pull!!

Also, if an engine hasnt been used for 4 years or so, but was broken in back then, can I run it fast, or does it need a sort of 're-break in'
