I just bought a EME 70 twin a few months ago but I just know got around to putting it on the airframe the problem I am having is it is hard to start it is getting fuel to the carburetor but I have to flip it probably about 50 times to get it to fire with the choke on, then if I take the choke off it will not start. If I leave the choke on halfway then it might start after about another 30 or so flips. But once I do get it started it runs very good it idles good it has good pickup and power and it does not quit. I did take the plane to the field for the maiden flight it took me a long time to get it started but once it did start I was able to fly the plane for about 11 minutes then I landed it to check fuel but could not get it to start again unless I go through the whole procedure of 50 or so flips so after my arms were so tired and sore I just quit. I did notice that the engine did have eme spark plugs in it. I wonder are those the right spark plugs or is it something else that is causing my starting problems I just wanted to know is there anyone else who have had this problem who could offer me a solution it seems like the company does not want to help unless I send it back and pay to have them find out what is wrong. Even though there is a 18-month warranty on the engine they still want to charge me.
