Alot of the time original carbs can be repaired
To be fair this is unusual for forum members to support aftermarket China cheap parts![]()
Joe, in years gone by there was a problem with some of this gear but that has changed and they have really upped their game. What has also changed is most of the OEM gear is made in the same place, I don’t think twice about fitting these carb and coil kits, never had an issue. Only thing that I throw away out of these kits is the supplied fuel pipe.

For Stihl stuff I have got rebuilding the carbs down to a fine art and a 100% success rate. It's cheaper cost wise for me to buy a £5 repair kit and know it will work.
But - I do have a Honda GX 420(?) Powerhose that has sat for 10 years. In terms of aftermarket carbs is there a specific source or better - a "brand" you have success with please?
Yes, it's dead. I disconnected the kill switch wire yesterday.If the small wire that goes to the coil kill switch is disconnected/cut from the coil or switch (depending on the design), the wires sole purpose is to ground out the coil to stop the spark, the coil will spark if it's working, therefore no spark equals a dead coil unit .
Even if the flywheel key/keyway has been damaged and the flywheel has moved on the crankshaft, due the design of the engine there will still be a spark if the coil is working, the spark may not be at the correct point in the engines cycle to run, but being as the pull cord works directly on the flywheel and the flywheel magnet are passing the coil there will be a spark if the coil is ok, just not in the right place.
The only other problem will be a damaged low tension lead for the coil grounding out, causing no spark or a fault kill switch, both for which are eliminated by disconnecting the low tension wire from the coil.
I'm hoping the carb is working. I'll find out when I can get a spark.Alot of the time original carbs can be repaired if the individual knows how to correctly clean and adjust them which I do. But alas, agree - buy any carb members believe works for them![]()
Joe, do you by any chance have a workshop service manual (not user manual) for honda lawnmower engines? You probably don't need it yourself, but I have little experience servicing these things.Having repaired around 30 small engines myself in the past year or so and having seen not a single good aftermarket coil or carb aftermarket myself I disagree and won't be convinced otherwise. Yes they ran but with experience I knew it wasn't right and sure enough original parts cured any issues.

Yes, YouTube is useful. One guy mentioned the Honda service manual, hence my asking.Sorry it's a hobby and Stihl stuff that I work at so I don't have Honda manuals available unfortunately. I'm sure you tube will have results on diagnosing your engine, have you tried that yet?
Agreed entirelyClean the rust off the flywheel magnets with with fine grit wet and dry, same on coil contacts. Turn the flywheel so the magnets are where the coil sits, loosen coil bolts, piece of cigarete packet or similar thickness cardboard between as a spacer, magnets will pull the coil into place, tighten bolts, remove spacer, spray with wd40. I have sorted a lot of lawnmower engines that way that were sparkless.
I'll give that a go. Thanks.Clean the rust off the flywheel magnets with with fine grit wet and dry, same on coil contacts.

Google is your friend, just a start:-Joe, do you by any chance have a workshop service manual (not user manual) for honda lawnmower engines? You probably don't need it yourself, but I have little experience servicing these things.
No, that's the users' manual. I believe there is a technical service manual to be had somewhere. According to the YouTube video mentioned in my first post, the manual specifies resistances for the primary and secondary coils. I'd rather read that myself than rely on the video.Google is your friend, just a start:-

It is a first for sure
