Hi. I have finally solved the excessive vibration problem by mounting the engine on a soft mount. The engine started fine and ran great but here is where the problem starts. I started the engine with the needle valve open 2 turns. At this time the engine was running rich, I tried to lean it by turning it clockwise and i turned around 1 full turn but there was no change in the rpm. Basically leaning wasnt making any increase in rpms. I stopped the engine and tried to restart. Trust me i tried around 20 times but the engine did not even start for even 1 second. Changed the prop,glow plug,fuel lines but no avail. Im assuming that the engine is flooded so i took off the glow plug and ran the engine with my starter, still it didnt start. Any advice on what mite be wrong or what i can do to make it start again? Any other way of unflooding the pump? My fuel lines are coming from the fuel tank to a filter then from filter to remote glow fueler valve and then from remote glow fueler valve to the engine. The vent line is open to the air. Fuel is 20% klotz, 5% nitro and rest methanol. I showed it to experienced guys at the field and even they couldnt make out what is wrong since this is the first dingo in this country. I know this is lengthy but plz try to help me because I really am frustrated. This is a new engine with only 2 flights and now im spending hrs on the field just to make it start and still it wouldnt start. Thnx
