I posted this in the homeowner forum but haven't got any responses yet. I picked up this mower cheap ( 10 Bucks) and it will not run once I take it off choke. The choke was a froze up and was stuck on. I cleaned the carb as best I could, cleaned and lubed the choke linkage and I think it works freely now. I had to replace the idle ? mixture screw in the carb and it doesn't seem to change anything when I adjust it. The previous one was snapped off clean but I was able to get it out. The shop where I went to get the parts says the manuals are very spendy and take months to get there. I think it needs a carb rebuild or something else is going on with it. It's pretty beat and looks like their idea of maintenence was as long as it didn't fall off it was OK. But it still moves pretty well and it cuts just fine when I can keep it running on choke long enough to engage the blade. It just seems to go way lean off choke and will run about 30 seconds then die. It also surges a lot under no load but the manual I was given claims that is normal because of the emmisions stuff. It's just the intructions manual for the newer version and has no repair info at all. I would like to do this myself and save some money, the lawn shop says they'll tune it up for 75 bucks plus any extra parts. That is sposed to inlcude a carb rebuild. Any ideas for this or is that a good deal and I should just let them hassle with it? Its a fc150v-00 engine I'm pretty sure by the way. Thanks, Terry!
