I have a freebie 240 that I am starting to take a liking to it's a little hard to start, but once it's running it starts first pull between cuts. Is there a throttle lock supposed to be on this model I don't have an owners manual. Or is it just start on choke and throttle set at idle. It has good compression. Thanks Dan

I think it is only the 245 that has a throttle lock - I don't know why as the engines are identical, with the additional manual oiler on the 245 being the only difference as far as I understand it. My 240 can be difficult to start, but I have found through experimenting that it does not need the throttle to be opened as you pull it over - quite unlike my small XL models that seem to like full throttle during the start procedure. With my 240 I use full choke and no throttle until it pops, then half choke until it catches and starts at which point you can give it some revs. I have found mine needs a few seconds of gentle revving to warm up on half choke before moving the choke control to the off position. Mine has a Walbro WT carb fitted which is very sensitive to the tiniest changes to the Lo running needle, and it has taken some time to get to the right settings. I still tend to run very slightly rich on the Lo needle otherwise I get a hiccup as it transitions between Lo and Hi (unless it is very well warmed up), which can be a pain if I only need it for a couple of cuts. A good saw - light weight but reasonable power. I have used mine for tree pruning and major surgery on big hedges.
