Hi Marcel. Thank you for your reply. The fuel filter is about 200miles as changed it when I upgraded the fuel lines and the air filter is about 700miles. Both are free from particles. However the carb hasn’t been touched by myself as I’m not overly confident in touching the carb. The spark plug is quite dark black. Also the manifolds are okay, no leaks
