i have tryed every thing that had been surgested and still nothing, any more surgestion????????????????????

[clmintie]

Has the kill switch wire got trapped under the tank and is now shorting on the frame? Happened to me on a TM125 Suzuki, it had a steel tank, every time I kicked it over, I got a shock.....

[FA50 rider]

na its got a spark and im not getting shocked thanks any way

[clmintie]

One last try... Did you leave a rag in the exhaust port when you put the chamber back on???

[FA50 rider]

no not that ever

Well try a bit of spray ether (engine start) to try it out. Best with airfilter out (& good to have extinguisher handy, but more on a 4 stroke as they can backfire worse).

Boom are you 14? Buy a Honda (Or insert another make) Its as moronic as the Holden/Ford mantra

Is fuel definitely getting into the bike - is the spark plug wet after you have tried kicking it over a few times?

Have you tried roll starting it / pull starting it - that can be one way to get a stubborn bike to start.

I have found that when cleaning out the power valve, if you dont need to have the top apart for doing rings etc, its just as quick to pull the engine from the frame and do it on the bench; saves taking the barrel off and having to replace gaskets.

yea ill try push starting it tonite and i didnt need to take the head off so i saved me self a gasket

My advice is your waisting your time floggin it to death anymore. I am making the assumption that it was going Ok B4 you took it apart. You have been tryin to start it for a few days now. A 2 stroke will either start or not, especially if you have tried all the simple things like a new plug etc.
You will have to go backwards over the work you did.
Make sure it has good spark.
Then probably the tank and carb was one of the last things you put on so start there make sure fuel is getting through. E.G. Floats are not jammed closed or open etc etc.
And then on back from there, till you find something you can pin down.
Back firing usually indicates to much fuel that is partially firing or timing is out.

RMX is the 2 stroke isn't it. Not to good on my early Suzukis.

P.S. I very very rarely take the head off the barrell.

Try what dave said a squirt of Ether,
A new Plug as the plug could spark but when under load it cuts out
Check your timing is lined up properly
Wind the air mixture screw in countinghow many turns record this down and try turning it out 1 and a 1/2 turns,


And my YZ did this it didnt go so what I did was put it in gear and ran with it it spluttered and spluttered and then fired as you may have flooded the crankcase

cool thanks for that info,will try this stuff 2morrow
