Yes thanks for all the help and suggestions the needle settings is what the manual says I did check them and where I have them set is where the engine runs the best the spark plugs are the ones that they sent with the engine. The compression seems good the fuel tank is hooked up right I know that I've been doing this for approximately 35 years,the engine is brand new so it should work if not they should stand behind what they sell without wanting to charge me more money to find out what is wrong with this engine I have six other gasoline engines da engines,zenoah engines, OS engines,dle engines, and none of them give me any problems except this one. It should be something pretty simple I would think because once I do get the engine to start it does run really well the problem is it takes about 20 to 30 minutes to get it started. I'll just have to try to sell this engine and tell the person the problem that I have before they purchase it. From now on I'll just stick with desert aircraft engines and never buy EME engines again.
