Long story short was out this weekend testing for an upcoming NSS race at MIR Saturday fought some tire spin issues but my son made his debute in a Jr dragster so we load up this morning head to our local track I unload my car fire it and the throttle sticks I kill it instantly so no harm I pull the hood and find the throtle blade screws are loose that hold the blades to the shaft causing the throttle to hang up I pulled both carbs tightened the screws reinstalled hit the starter and while cranking hit the ign switch and BOOOOOOOMMMMMM the intake explodes ripped the top off and I have a blowoff valve on the intake to prevent this well at least my son will race this year as I am Done
