Yeah. My wife's father had given her this blue colt. I was told to put a lil fuel in the spark plug then it would start. Had this for 7-8years then the engine played up. We found a red colt for sale, have used it for a year or so. The pedal mechanism is opposite to the blue colt, blue colt pedal down to go.. Red colt pedal down to stop. Pain in the arss the red one. It had a disc brake on it. But i liked the blue colt better. So my old man pulled mine apart painted it and reassembled it. We even took the motor off the red colt and used it on the blue colt. Was working great, then a few weeks later mowing my yard it decided not to hold on the hill once I take my foot off the pedal.
We got the braking arm lever off. Drilled out the rivits that held the brake pad ( the brake pad was hard as a rock) we sent to a small engine mechanic and he replaced it with a newy.
It still don't brake, doesn't even hold on a hill when I take it down a hill untill it stops it's self.
So that is my problem.
