Cobra 50 fourwheeler wont start cleaned carb and new plug

SOURCE: I have a LT 50 2002 wont start have spark, 120psi

have spark and compression but do you gave good supply of fresh gas?

SOURCE: wont start

Hello;
If it starts with ether then you have spark, compression, and air. All you need is fuel. Make sure that you have fuel at the carbs and that the fuel is flowing to the cylinders. Check that the petcock is open and free of debris. Hope that helps;

Has it been laid up for months? Did you leave any gas in it untreated? You may need to boil out the gas tank . Try a carb cleaner first that you add to the gas.Check the plugs.Are they black/oily (too rich / worn ring), Tan ( correct ).they tell a lot about the condition of the engine. Good Luck

SOURCE: it started bogging down when riding and now it

hi buddy are you mixing it correctly with a mixing bottle with 40:1 ratio also on the carb will be a screw mixture screw turn this all the way in and unscrew it 1 1/2 turns out and try this also is there compression get back to me

SOURCE: starts hard and wont idle, no low end power, has

The starting hard and Idling problem sounds like carb needs cleaning. If this bike has moved from a different area it might need different jets in the carb. I might have jumped the gun the gas/oil mix ratio is very important check that first. your spark plug should be a golden brown when mixture and right jets are in. This might resolve the low end power if the oil mix is to rich or you might need piston rings. GOOD LUCK
