Old Lawn Boy 21 inch walk behind has been designated to shuffle off to the cottage after 25 years of faithful service at my house. The final straw was a failure to start event. About 1 month ago I had the same thing happen and solution was new NGK plug. This time not really certain the issue, but I thought that perhaps the primer was sending too much fuel? the plug looked very wet. Last time this happened I tested the spark with the new plug and it looked bright enough. Doubt it's the ignition module? but after 25 years it might be weak?
Who makes a good carb rebuild kit for this one? the research shows it has a Techumseh 4.5HP engine, it has always had premium fuel to avoid issues with ethanol wrecking the rubber components. Carb is Techumseh 632078.
Thanks in advance,
Ken
PS I got a new Troy Bilt 21 inch walk behind with the Honda 160cc engine for home, it cuts quite nice and the handle is better suited to my height than the old LB.
