Hello.. I’m new here and please for advice, am desperate. So.. I bought a RR a few days ago, used.. In the invoices it says : -new ignition -new spark plug -new piston -new cylinder So this, so first with a friend a few things checked.. Carburettor cleaned, air filter is ok, intake stop ok, cylinder removed, seals and pistons checked spark tested, other spark plugs used, couple times pushed around block, power is enough there, sound sounds auc h good, but it just doesn’t start. I really don’t know what it can be anymore. The engine is a Minarelli Am6. 2-stroke,water cooled Can anyone possibly help me or make assumptions ? Greeting
