has anyone had any major engine problems with their new honda self propelled 5.5 hp lawn mower?
i got one about 2 mo. ago after 1 mo. it started running poorly. i took it in and they say it has a faulty intake valve. seems unlikely, but i know it isn't the fuel, spark plug, or dirty air filter.
i'll let you know asap if that is it.
ok....i was told it was an intake valve by a "certified" tech. let me be very precise. from day one i noticed after the engine ran a while it seemed to sputter a bit and a little (very little) black smoke came from exhaust. i thought little of it. figured it was just breaking in or something. after each week the condition became progressively worse. finally after 4-5 weeks of use it became so bad it would barely run. i dumped the fuel outta the tank and put hi test in, replaced the plug, and cleaned the air filter.that really made no difference in the way it ran. i took it to service ctr. thinking they may have an insight as to the prob. it sat there 4 wks. til today 8.22. i finally got tired of waiting and picked it up. taking it to a more reputable shop (hopefully) tomorrow. i've always been told that 90% of fuel problems are electrical...which i have many times found to be the case. i have a hard time believing it is an intake valve in a mower this new. can u add n e thing?
also as a footnote (now that i am home and have the manual in front of me) it is a model hrr216tka harmony II gcv160 mower. thanks

you say it seems unlikely to be a faulty valve – are you a service tech & who told you this. First place I would look at would be carb but you saying its running poorly doesn't really explain what its doing.
Clogged carburator needle.
A new epa carb has no needles to adjust….. plus a needle can't get clogged…… beleive he's refering to the jet….. main jet to be more exact….., and it could very well be the problem……
Fuel problems are fuel problems, not electrical. It does sound like you have a fuel problem(carburetor) black smoke usually indicates it is running rich on fuel. If the fuel were blue it would be a sign of burning oil. Doesn't seem likely to be the intake valve.
