-at first engine ran fine, but towards the end of the day kept choking, despite being ran sufficiently lean
-seems to be carburated fine, but then after 1/4th lap on the track chokes for no apparent reason
-engine has truckloads of compression obviously
-front bearing is cheapo €4 ebay bearing

I'm thinking this means the cheapo front bearing has let go? Even if it has only less than 1 gallon on it.
