Doesn't look like that was the answer AVB, compression is fine, valves opening and closing as they should. I was expecting something like a broken cam but that all checks out as it should, got me a bit stumped at the moment. I will swap the carby, but I don't believe that could be the prodlem because even with a bit of fuel or strater fluid down the carby I don't get the slightest indication that it might fire
