Apologies for delayed response to your email. I only managed to find time to look at the mower again yesterday. i cleaned the air filter (bit oily) and refitted. The engine runs a bit smoother now but I still have the intermittent drive problem. Sometimes it works and most times it doesn't work. When I engage the handle, there can be a delayed reaction or none at all. sometimes if I move the machine back and forward then try again, it works but as soon as I stop or release the drive handle I have to go through the same process all over again. I checked the gearing under the rear wheel hubcaps. They appear in good condition. I also tried adjusting the cable. This made no apppreciable difference either - probably worse. Wondered if you have any ideas?
Hi Curtis. Drive belt is new and tight enough to drive.
