Hello everyone, my name is Rui i'm Portuguese and recently found this excellent forum, the problem is, I have a Casal Super Boss, in Portugal are the best known and mopeds were made in Portugal, probably already have heard something about the Casal Huvo or Huvo engines, racing engines were basically developed in Portugal.
I bought this moped will some time and the problems that I noticed was that it was in progress when it starts to warm up the engine began to send some backfire, turn off and go back to turn on and turn off times and only managed to turn back on after enough cooling. This problem was solved with a new flywheel, new flywheel with ja could walk without turning off the engine and no backfire Itself and was always able to connect the motor to the first kick.
But the bike will soon no longer run on idling When warmed up, to do that i need to speed up a bit with the throttle until it dies, the problems mentioned above do not happen again but the engine can not hold on idle Itself, if the engine is cold can hold the idle but as soon as I have done a ride of nine miles without ever stopping (just for once to go back) when I get home can not hold the engine idle.
Do you have any idea what might be?
