Why won't my Roketa scooter start?

by Tom
(Logansport, Indiana, USA)

My Roketa 49cc scooter will not start, has spark, will not fire with starting fluid. Has gas when vacuum is applied. Has compression, at least when checking with my finger since I do not have a gauge that small. Any thoughts? Thanks

New battery, cranks over, has spark, has gas and we are still breathing so it has O2?

Mark C,

Roketa 250 starting fix NEW
by: mark c

I have 3 roketa 250 scooters. Done would start until I installed a simple fuel primer body. Takes about 45min and mounts in the glove compartment hole already in place. Also there is a fuel tube already in the intake in front of the carb to attach the fuel primer tube. I used large small engine fuel tubing thats about $10.00 from a weed eater store. Bought the fuel primer body off e bay and also used on seadoo and snowmobile products. This fixed all three scooter and now will start in 40 degree temp. Just push 3 shots of prime and away you go with your roketa. Enjoy :)

Also if you've had it awhile, check your valve clearances. Should be .003 inch. Valves too tight will make a scooter hard to start.

Try This
by: Jim Zeiser

Pull the spark plug, spray starting fluid into the engine, put the plug back. Try it then. If you've been trying to spray it through the carburetor it might not be getting through. Too long to explain why. If it runs and dies. Fuel delivery problem. Carb needs cleaning or diaphragm is out of whack in carb.

Battery Tender Junior in package

A battery tender like the Battery Tender Jr. can make all the difference in whether your scooter will start right up each spring, after being stored for months.

Just about every scooter owner needs to have a battery tender, sometimes called a trickle charger. Unless you are lucky enough to live in a climate where you can ride all year long, chances are your scooter will be put on ice, figuratively-speaking, for at least a couple months every winter.

One of the key steps in winterizing a scooter is to protect your battery from draining during its "rest" period. This can – and will – happen if you leave your battery sitting untended in your cold scooter over the winter, even if it's in a garage or shed.

Read our review or go right to Amazon.com to buy this highly recommended Battery Tender Jr NOW...
