Hey Phil, hope you had an air filter of some sort when you were using it! but good stuff.. great machine when easy to start.
keljad, you wont regret it. best thing to do i found with the 4mixes is unless its 10 degrees or less dont bother with the choke. 99% of the time mine start first pull without any throttle or choke or priming.
Im actually trialing a more permanent fix but didnt wanna post it up here in case i blow the engine lol. ive disconected the vent pipe from behind the air filter holder and will block with some stocking or similiar and cable tie to keep dust out. will post an update after the trial ... if anyone can tell me a reason why that's not a good idea please let me know! the way i see it is its a breather like any other tank but instead of getting the air from just outside the tank its getting filtered air from behind the air filter.. so as long as im not letting dirt in anywhere then i think it should be ok .. thats my theory anyway.
