Hi guys, hope you could shed some light for me. I’ve just fitted new crank seals etc and refitted engine. At the moment I can’t get it to start. I’m getting lots of backfires and it try’s to start on the left cylinder but it won’t catch. Carbs were fine before but I’ve cleaned them out and changed plugs. I believe I’ve put everything back as it should but is they’re something I’ve maybe missed that would cause this? Hoping this is something simple, I’ve spent a fortune repairing and replating the cylinders already. Cheers
