Hi, I have an OS52 surpass which will only start after LOTS of priming after which fuel pours from the carburettor. When the engine does start the rpm is not stable and tends to drop even at full throttle until the engine just quits.
I'm not hugely experienced with glow engines but have followed the manufacturer's instructions to start it - I don't know if the fuel leaking from the carb after priming is this normal or not? The engine is used but doesn't appear to be overly worn.
The revs also drop when I remove the fglow plug clip, i do leave it on for a bit to allow the engine to warm up but this doesn't seem to make much difference. Many thanks, Rob
