Dont know if this will help but i had a similar problem with mine. Started first go, ran fine while it was cold then once it warmed up it would missfire. I have the 4y non-injected model engine in mine. i went through most things as well and my prob turned out to be the wrong plugs were installed. In spare parts catalogues my engine is listed to have ngk bpr5es or equivalent plugs with a 1.1mm plug gap. Yet the correct plugs are meant to be bp5ey or equivalent with a 0.8mm plug gap. even setting the incorrect plugs to the 0.8mm gap didnt solve the problem. I got the right plugs and hey presto. havent had a miss since. Hope this may help rgds, Kevin
