not that i can think of , should clear in about 5 mins . its been having a tough time of it though , might be just full of old stale fuel and we know they dont enjoy ! just have patients i had one once . took about 10 min's to clear and smoked more than 10 men , still going strong now though , swapped it for a thing of interest with a mate and its still cutting bush to bits now !!! almost trashed but engine is still good
