Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Hi, my name is***** will be assisting you.
The timing marks are actually internal on the crankshaft gear and the camshaft.
Depending on the age of the engine you should see either a dot or a line on the crankshaft gear at one of the teeth. The camshaft will either be a dot or a little notch between the teeth on the gear.
Yes you want the two marks lined up together in order to have the engine in proper time. If you don't the engine will not usually start due to the valve timing being off and the spark will not be at the right time.
Thank you it has been a pleasure to assist you.
