Scary thing happened while driving the pinz today

Post by audiocontr »

We will make this a challenge... Lets see who the first person is that figures out why or how the following occured:

While fully loaded with home articles (we're moving), I drove my 712m down a decently crowded main artery in Northern Virginia. Its 2-3 lanes and stop and go traffic due to traffic lights.

In my normal 1 - 2 shift, I realized the gas pedal would not return to its highest point as i depressed the clutch. The engine RPMs soared. I shifted quickly and landed in 2nd accelerating at a steady pace. The gas pedal would push about 25% further to the floor, but when i let up, it would not return. As my slow beast accelerated, it eventually caught up with the mass of traffic at the next red traffic light.

I can't push the clutch in or the engine soars, but i can brake so i slow down the best i can. the engine hesitated and started to die as i came closer to full braking. I eventually have to turn the engine off in the middle of traffic.

As the light turns green, i start the truck again and quickly let up into first, eventually pulling over to a safe place.

What did i find when i pulled the doghouse?

A piece of stick or other debris interfering with throttle cable deployment?

We are on the right track. Close enough in fact :lol:

The swivel bolt which holds the air intake onto the top of the carbs fell out of the eyelet. I must not have torqued it properly with the flat head screw driver. It fell out and down, lodging itself below the rear carb throttle arm. Scary indeed!

Wow! I was just putting mine back together a couple of days ago and that bolt caught my eye as a potential problem area. I installed a Nyloc nut to hopefully deal with the vibration but now after reading your post I'm ready to add a serrated washer too! :shock:

I removed mine. Don't think it's necessary to hold the intake plenum in place.

What you described happened to me on my trip home with the Pinz....my issue was a matter of complete inexperience however. I was playing with the throttle lock while on the highway, but I disengaged it eventually....or so I thought. I got off the highway and was coming to a stop sign on the ramp, but when I depressed the clutch the engine just went crazy! Scared the shite right out of me! I couldn't figure it out right away, so I did the same as you and shut the engine off. My buddy told me to check the lock, and sure enough, it was not completely released. Lesson learned!
