Carburetor - Part # 1602609 Mfg Part # 20 853 33-S


RepairClinic Item # 1602609

If the lawn mower does not start, the carburetor might be clogged or have bad fuel in the float bowl. If old fuel was left in the lawn mower for a long time some of the volatile ingredients may have evaporated, leaving a thicker, stickier product that is more like varnish or shellac. This sticky fuel can clog up the small jets and ports in the carburetor and it can be difficult to burn making it hard to start the engine. The only solution is to drain the old fuel from the float bowl and thoroughly clean the carburetor with carburetor cleaner. If that isn't effective, the entire carburetor may need to be replaced.
