Problem for solving RM250

[vanja_cr250]

Suzuki Rm 250 2 stroke. I put new cylinder with new piston everything is assembled very correct.
when i start the engine it wil work 10 seconds and it gonna stop.
In the next 10 pushes of kick starter it will start again and again the same.
Lot of Compresion, Carburetor clean, Float level ok spark ok ignition ok, intake ruber is new.

Only the crank-shaft seals are not replaced.

Any sugestion? :bang:

i'd check that float level again. once i swore that i had my float correct, and i tried for a while to get it started..then iadjusted it again..and it worked great..

I found the solution.

ball bearing on crank shaft staked not roling enought smooth
i replaced them and now it is like new.

i thing this is good expirience thanks to everione :ride:
