I bought a Honda HRR 216PKA K9 series a few months ago. The mower worked perfectly well when I first bought it. However recently, the engine keeps on lacking power and stall. This lawn mower has self propel facilities. I want to know if the self propel mechanism is driven by a belt or gear. If so will the belt slips if the grasses get lodge into the pulley that drives the belt. Also is there any fuel mixture screw I can adjust the fuel mixture of this engine as I find the engine is lean on fuel and maybe this causes the engine stall. Can anyone has this problem with the same Honda Engine?
Thanks
Often, a lack of power or poor running engine is a sign of incorrect fuel/air delivery. This can sometimes be narrowed down to dirt or debris inside the carburetor, or clippings blocking the choke linkage, etc. As your mower is still under warranty, you may want to have a Honda dealer inspect and isolate the real problem. Factory defects are normally covered under warranty, but communicate with your dealer and let them know not to bill you any time without your approval, as the actual problem may not be covered under warranty.
Can you replicate the problem without engaging the self-propel? If so, you know the issue is not related to the self-propel. All Honda HRR mowers are belt-drive. K9 models use a slip-belt design, where the belt is tightened to change speed. Earlier HRR models have a constant-tension belt and speed is controlled by an internal clutch inside the transmission.
You really don't want to change the fuel mixture for a couple of reasons (1) The EPA doesn't want you to because it changes the emissions of the engine, so they require the screw to be tamper-proof (it will snap off and break if you twist it too much) (2) It likely will not fix the issue. It is more probable there is something wrong with the carb or choke, probably gunk in the fuel, in many cases.
Often, a good cleaning and inspection of the fuel system (air cleaner, choke linkage, etc.) can help, and sometimes, it is faster/easier/cheaper just to replace a problematic carburetor. List price for a whole new car for this model is less than $16, and it is not hard to change out. Much easier to swap than to try and disassemble and clean, FYI.
The part number for a new carb is 16100-Z8B-901, and here's a link to find a Honda dealer:
