I recently purchased a Victa Special 2. I'm a bit perplexed by the air filter canister on this model. It is the same shape as Victa Mayfair canister, only in this case it does not have a removable cap on top. In fact written around the top in raised lettering is "This cap cannot be removed". I thought I might be able to get into it by disconnecting it from the handlebars and the throttle lever, but still no go. I can see the filter inside the canister but it seems to be a permanent fixture. There doesn't seem to be any way to remove it. I can only guess the operator had to just blow the dust out of it and keep using it? Or am I missing some trick to removing the filter? confused
