pressed the cell button.<\/p>\n\n\n\n<p>There is exhaust from the muffler, and the engine sometimes starts.<\/p>\n\n\n\n<p>If I turn the cell a few times and blow the accelerator, the engine will start.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p>I remember being in the same situation before in Potosi, Bolivia<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-wp-embed\"><div

one, so I don&#8217;t think this is a problem.<\/p>\n\n\n\n<p>I tried starting the engine with it removed, but there was no change in the situation.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p>Next I check the spark plugs<\/p>\n\n\n\n<p>When I replaced the cylinder head in Uruguayana, Brazil, I also replaced the plug with a new one and drove it for about 18,000km since then.<\/p>\n\n\n\n<figure

suspicious.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p>The fuel pump has been around 20.000km since I replaced it in Rosario, Argentina<\/p>\n\n\n\n<p>It is generally said that it needs to be replaced between 50,000km and 100,000km, but this is reasonable since the original one broke at 47,000km.<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-wp-embed\"><div
