Ran an Autocross yesterday.
First run: Clutch slipping like crazy. Only needed adjustment.
Second run: Damn thing wouldn't start. The little battery wouldn't turn my new engine over, too much compression. Gotta change back to the bigger battery. So some guys push started me. Clutch better but still some slipping. Clean run no cones.
Third run: Clutch is really hooking up and I was flying. Than at about the 3/4 mark, the gas pedal goes to the floor and the engine dies. I check it out and the bracket at the cable and the gas pedal has bent and the ball/socket has come off. I don't have a "stop" behind my gas pedal and when I pushed the pedal too far it bent the bracket.
So I need to fab a bracket for a gas pedal stop. If I had the stock floor board that goes behind the pedal, it wouldn't have happened. I'll make it so the stop is a bolt that can be adjusted in or out so the pedal stops when the carb linkage is fully open.
It's always somein' ain't it?
BTW, my second run with the slipping clutch was good enough for the 3rd overall quickest time.
Damn Paul, you finally get the motor running great, then you can get it hooked up.... When's the next event? Congrats on 3rd, who beat you?
BTW, if you need a floorboard for measurements, I've got an extra one...

well done paul, what are you running for a clutch?
that motor makes tons of torque, even down low. First time I ran it I wasn't sure if the tires were spinning or the clutch was slipping.
i got one of the fancy aluminum floorboards from engman "i think", its too heavy for your taste but looks great and uses the original clutch and throttle stops.

I'm runnin' that stock clutch I had in my other engine/tranny. |
Great job Paul, Once you get it reliable and gain confidence in your ride you can concetrate on the course. TTOD is only a matter of time. I suspect nobody will be within a second of you when all is sorted.

Paul, Do you have any idea how much paint WEIGHS?

I had my gas pedal fail in the same way last year. Popped the ball joint back in for the next run, only to have it happen again just 100 ft short of the finish.
In my case, it wasn't lack of a bottom stop, rather it was that side force I was putting on the pedal. In going quickly from brake to gas, I often don't get my foot aligned vertically with the pedal. My heel tends to stay about half way between the brake and gas, so my foot is then angled to the right when I'm pushing on the gas. Push down hard and dealing with high g turns then produces a lot of side force on the pedal, which the stock joint wasn't really designed for.
I mention all they by way of saying that you might want to design you pedal stop with a ear or something to take any side force from the pedal.

Andrew,
Excellent input. Now I need to figure out how to do it.
Maybe some type of rod on the right side of pedal that the pedal slides on. It would only go up/down and not side to side.
I never liked how the pedal is sorta flexable at the base of it. I could put a hinge at the bottom that is tighter than the sloppy rubber hinge.
I'll work on it. Thanks
