Oh after careful review I believe I found the cause of my failure..... The o-ring under the needle set was bad on the carb the caused my hydro lock. I didn't know these carbs had the filter or o-ring until now. If it's news to you too, ya might want to look next time you clean your carbs. I had a bit of crud in a couple screens and a $.040 oring cost me $600 in crank repair and rebuild costs.
