first what model engine and carby set up. Second try this give it one pull and pull the spark plug out and check if it is drawing fuel through. Have you set the armature gap to the flywheel. Have you checked the spark plug for good spark. If you are pulling and it gets fuel and spark and wont start try removing the exhaust and see if it starts. If it does it is not breathing properly. Have you checked and set the valve clearance.
