Hello!
My 80/66cc engine was running sweet the other week in about 12-15+ deg c temps, plug was a nice dark pink. All was well.
Over the past few days it's got very chilly. So much so that it's been taking a lot more effort to get my bike started. It'll start but won't idle, and when I'm rolling it'll jerk about like a kangaroo until it's all warmed up. It was also a bit flat at full throttle.
So, I moved the magic C clip from the second notch to the third notch thinking that as it's much colder now, the air is much denser, and hence will need more fuel. That made it much easier to start and ran much nicer.
However, this morning it was -2 degc, I did my usual start, choke on for about 3-4 pedal strokes and it was running, as soon as I took the choke off it died. I pedalled a bit more, let out the clutch and I was off, although a bit like a kangaroo. Then it died when I pulled in the clutch to stop at a junction, and I couldn't get it going again at all!
It's annoying as a friend of mine who I commute with has the same kit and his bike was totally fine this morning! His needle is on the middle slot and it starts with only a second of choke and then will idle all day nicely.
Hmm! Once it's up to temperature it runs nicely when it's cold outdoors. Any suggestions? Other than using a heatgun to warm up the block before starting! Which isn't really an option as it has to be stored outdoors during the day so gets very cold!
Thanks in advance!
