Another weekend of fun . . . NOT!
Fueled up on Sunday and spent a couple hours mowing. Then ran out of gas. Grabbed a fiver and put it in. Tried starting, no go. Remembered the plugs: Sure enough, two of the boots were off. Purchased some new plugs (again), NGKs this time. After putting them in, I found I could start the tractor, but it would only run on full choke.
On Monday morning, I pulled the carb. Just for grins, I opened the fuel valve -- NOTHING! Grabbed some rubber hose & carb cleaner and attached the hose to the higher end on the fuel line, then filled it with carb cleaner and blew out with compressed air. HOLY CRAP, did the crud come out the fuel line! Repeated several times until it came out clean. Also, cleaned the sediment bowl. Then I hooked up the carb.
Started right up, idled fine, and had great power when I opened the throttle. I spent the next four hours mowing without a hitch. When I shut down for the day, I checked the plug wires -- still in place, just like when first installed. HURAY AGAIN!
Conclusion: Autolite plugs are trash, NGK seem to hold up much better. I forgot that fuel can gel up in the fuel line. What surprised me is that this can happen even when I religiously use Sta-Bil every fall. Hopefully I won't have any more drama.
