won't start By pepere (Read 1,078 times)

We love our 2008 Roketa 250cc motorscooter. However, it is very hard to start. We figured out that they flood very easily. So I usually only prime it one or two times. It still takes us 1/2 hour before it kicks in. Once it gets going, it will go forever. It turns over very well, but just won't start. thanks, russ

Hello Pepere, can you advise us which engine you have, the 244cc vertical Honda clone or the 257cc Linhai horizontal engine, that will help everyone help you. 1st of all if you say it floods easy and you have to prime it to get it started but runs well after starting we can assume its getting fuel so there could be a number of things wrong or simply need adjusted. Not knowing the maintenance history or age or miles, have you ever adjusted the valves or it could be due again, out of adjustment valves can make them very hard to get started or keep running. Your electric enrichener(choke may not be working). You may have a vacumn leak causing a loss of vacumn which could hinder it starting. Your carb could just be out of adjustment. Could you advise what you have or have not done and miles etc and you will get a ton of suggestions on what and how to do it. Barnie

What do you mean you have to PRIME IT?

When did you last adjust the VALVES on it?

They should start with 1 or 2 hits on the start button.

I have the 2008 roketa MC-54-250B starts first crank, (It is the 257 linhai horizontal engine). I'd also check and make sure the enricher working correct.

Yep, a Roketa MC 54B 250, according to Roketa part manuals.

Mine is just a MC 54 250B and it has the vertical engine. I can not find any justification for the numbers on the rear panels. But 54 and 54B do seem to have some meaning in the parts manuals.

Bob, here check out my tag

Hard to read. But what I see is Displacement 244 300(?). Did I see that correctly?

Your tag is different than mine. I have mine copied but not in a form I can present on the PC. That will take me some time to do and right now I need to start my daily things not associated to scooter. I still think naming the scooter engine style, horizontal or vertical, is one of our better ways to describe our setups.

I have been trying to clear up how these machines were built and numbered but it seems that factory is one thing and then importers and distributors are possibly more concerns. I will try to get back to this conversation later. Have a good day.

It reads 244. 3cc which is funny since I have the 257cc engine

I just got my first scooter. a roketa mc54 250cc. unloaded it and will not start. boy i could use some help.

[sncshiner]

got the rear quarters off and dont know where to start. doesnt seem to be getting any spark

[alleyoop]

Do you have the KILLSWITCH on the run position? That is the red switch on the right handgrip. Also some have a killswitch on the sidestand make sure the sidestand is up.

Check the wires going to the COIL make sure they are connected.

Does it crank How do you know it isn't getting spark?

When mine sits for a few weeks, I must crank it for a long time til it kicks but it stalls 3 or 4 times, then something happens and the tach jumps up a few hundred rpm and it's fine. I just figgered the gas in the bowl evaporated and it is cold blooded.
