Office of Steam Forum for Model & Toy Steam Gas & Hot Air Engines

Well the new ignition parts arrived and were fitted ,thanks Jin , the engine ran but very fast, all the timings have been
re-checked and seem ok, came to start the engine a couple of days ago and the compression has gone, taken the
head off to see if valves were sticking but there ok so any ideas as to what my problem is now would be appreciated.
When turning the flywheels i noticed that air is being blown out of the carb does this suggest anything ?.
Thanks Trevor.
