Fix the problem is what you're supposed to do. Engines will run fine when the mixture is too rich. Running it that way it's not going to be easy to tell when you've got it too rich, especially if you're a novice with engines.

Fix it. Running with the choke on is a band-aide at best, and going to ruin your engine at worst. Running with the choke on instead of correcting the carb problem will as stated above wash oil from cylinder walls, contaminate your oil, and generally ruin the fucntion of the oil in as little as a few minutes.

What's the problem with fixing it properly?

i will get to fixing it soon, but i highly doubt running with the choke will "wash the oil off the walls" if anything its running it more rich,

You "highly doubt it"? Is that a scientific measurement?

Does you oil turn black and smell like gas after a short run? I think you said you changed it about five times already, what did it look like each time?

no, just intuition, i am going to get it fixed, but right now i have school, work, sleep, repeat, no time to stop and work, and ive got my hands full with the gearbox, its running great as is, i can run it without the choke but it bogs and i have no power, so it needs to be tuned, i will get to it this weekend, but as for now its running, and the engine is the least of my worries(with the hoot and all.)

i changed the oil twice, the first time it was blackish but still dark honey coloured, second time it was still light honey looking, but darker than new, i didnt notice any gas smell,

will take your words to heart though, you are the "Godfather of Motorized Bicycles"

i asked around the net, the majority said that the choke is there to get your engine to run right, and you should set the choke as low as possible, if half choke is where it runs best, then run it,

but i do want to run it without choke, im going to work on it, i just cant stop everything im doing to do it now, but thanks for the advice,

do the carb adjustment I linked to earlier...it will only take a couple minutes

then the choke should only be needed to start the engine (it is needed to prime the carb)

good luck
