Hi everyone! I am new to this forum but have a couple of questions. My son has a 2000 Husqvarna husky boy jr. 50cc. The engine is similar to a ktm. I am having trouble adjusting the carb to run correctly. First of all what ratio of fuel do i need to run because it is smoking pretty bad when it throttles up. Also it lacks power on take off until it gets up to speed. It used to just take off but now it will not. it starts and runs fine but maybe i am not running the right fuel mixture. If it is off will it cause this? Also do you have any suggestions on how to adjust the carb. it has 2 adj. screws. One with a spring and the other without that it smaller. Also how high of an oil level should i put the gear oil in the gearbox. Thanks Alot i am new at this as you can tell.
