I put the race car together today. I had the intake off and had the exhaust powdercoated. I had changed the jets in the carbs. I pushed it out of the shop hooked up water hoses to it and started it up. Checked dwell and timing and winged the throttle a few times, sounded good. I unhooked the hoses and decided to back down the drive [250 ft.] and nail it to see if it would break the tires loose. It did and the throttle stuck open. I couldn't stop after shutting down the engine so I went by the back door at about 25 mph and stopped in the back yard. I am thankful my wife didn't decide to step out the back door. Anyway found out that the accelerator pump in the front carb was hanging up at full throttle. Fixed that but no more driveway tests.Roy
Did that with my '59 chevy. Had a 396 with a 4-speed. The solid throttle linkage bound up in 2nd gear. I shut the key off and the throttle came back. I turned the key back on and blew the mufflers out. I was pissed so I knocked the rear end out the next time I shifted into 2nd. Had a little work to do when I got home. I wasn't pointed at the house though. Jeff
I ran a Honda Trail 90 into a house once, when I was in high school. Those things will popa wheelie if you start them with the throttle stuck. Most HA/GR's have a bit more power than that.
