What to do if choke on scooter wont start?
If the automatic choke is OK, the starter cranks the engine, there’s gas and there’s a spark then there may be an engine problem. You need to check the cylinder compression. You need a compression tester to do this. It screws in instead of the spark plug and measures cylinder pressure.
Why does my scooter not start at 100 psi?
If it’s 100 psi or less there’s likely and engine problem (bad valve, bad piston, failed piston rings) which will need the engine taken apart to find. Probably the most common problems are a dead battery or carburetor problems due to bad adjustment or build up of gummy deposits.
Why does my spark plug not start my scooter?
If your attempt at starting your scooter is met with only a small amount of sputtering, your spark plug may be the culprit—or your battery. If your spark plug isn’t sparking because it has broken, your engine can’t explode the compressed fuel. Spark plugs are relatively cheap to replace, luckily. Often there is an even simpler issue, however.
How can I check if my scooter has a spark?
To check for a spark, remove the spark plug from the cylinder, hold the tip of the plug against the cylinder head and crank the engine. You should see a spark across the gap.
