Carburetor

RepairClinic Item # 1652067

If the small engine runs poorly, the carburetor might be clogged or have bad fuel in the float bowl. If old fuel was left in the small engine 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 the small engine run poorly. 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, replace the entire carburetor.
