Bicycle Motor Refuses to start

You're right, you can leave it off. (which will also make it easier to pull the clutch lever!)
I've had many problems with the adjusting screws on the hand levers striping out, & just a little slack in the cable can cause the cable to fall off the engine lever...
I might actually try removing this spring for a few days to see if I like it better? (it does seem like a better way to go)

But yeah.. he needs to put that heat shield on!( you can see how his cable is melting)

it won't melt if he can't get it to run.

The carb gets the gas but it's not sending it to the engine or the engine isn't grabbing it from the card. My friend has actually blown through the carb to make sure there would be fuel flow. I will take the air filter off and take a look at what you said. What do you mean exactly by putting a small amount of fuel in the cylinder ? The hole in which the Spark Plug goes into ?

My problem is with the top of the carb. Isn't that knarly nut supposed to be down on the carb top.

all that is is for taking slack out of the bicycle motor throttle cable.

It's also a pic from last year. It was on a different frame last year.

If it WAS running good, with this carb... check to see if the jet or inlet needle are clogged!
Take the float bowl off.. the jet is the long brass tube screwed into the carb housing. make sure there's no dirt clogging up that tiny hole!
Blast everything with carb cleaner!
Also put on a in-line fuel filter.

Yes, the bigger, round one should be down on the barb, it's to lock the cable housing adjustment nut.

The needle is brand new. I didn't even have to proper one before. I do now. The entire carb is clean.

Yes pull the sparkplug out of its hole take about a teaspoon of gas pour it into the sparkplug hole put the sparkplug back in tighten it up put on the plug wire. Turn on your fuel. Breath in and out get on the bike put your feet on the pedals pedal it and then get out the clutch. If it won't fire then you have a problem get your buddy to look at it.
