Hi, my Mountfield RV45 has been running fine for years but whilst cutting the grass recently I stopped the engine and when it restarted it would only run slowly, like on tickover. I've changed the plug, cleaned the air filter, carb is clean with fresh fuel, all cables work correctly. Oil was a bit low so I topped it up. Has anyone got any suggestions please? The throttle has choke, fast and slow positions but these have never made any difference to engine speed.
Thanks.
Thanks.
