2013 June Sprints
Posted: Wed Jun 19, 2013 8:54 pm
Sorry race fans, very frustrating weekend and not much to report.
I worked the week before to replace the engine that I'd used at Brainerd with the engine that had lost the head gasket at last years Runoffs. I wanted to find out the issue in this engine. What I found was that the pistons were just kissing the head on the exhaust side of the spark plug on three of four cylinders, so I "massaged" the head and the piston wedge abit and used a thicker head gasket. But the engine in qualifying had no power and ultimately started "popping" out the #2 solex intake.
Took it home and replaced the engine again with the one I'd just removed, with freshened valve springs (down ~10% tension from new) on Saturday. Brought it back for the race on Sunday, starting 30th because of the poor qualifying (found a broken pushrod, #2 exhaust), and promptly broke an axle one the first lap! (that sucked). Due to attrition in the race, had I finished it might have been a podium!
Next up is Blackhawk at the end of the month.
