I totally agree with the need for a spring to return the PEDAL in addition to the weak carb spring.
Here is different one that got me a while back:
I pulled the air cleaner to squirt fuel down the carb.
When I put the filter back on, I did NOT tighten the clamp.
After a lap or so, the clamp slipped down over the carb linkage and it stuck on full throttle.
With no kill switch (yeah, I'm a fool) it was all I could do to reach back and stop a strong MC-6.
Solution:
My filters have a rubber casing at the top. I drilled a .500 hole in the rubber, so I can squirt into it without pulling it off.
Then I use a rubber stopper to plug the hole. Occasionally, I forget to plug the hole, but that is a minor problem compared to stopping a high revving Mac.
