Honda Generator Advice - No spark - Now Have Spark!
Hello LCB experts.
I have a Honda GX 160 5.5hp generator. Was using it to drill coupla holes, for raising the fuel tank. One hole successfully made, then the gen
coughed, and spluttered to a stop. It has never run since.
Here are the measures taken - so far:-
1: Suspecting a fuelling problem, I cleaned out the fuel tank and replaced the outlet/fuel filter and the fuel hose. Filled tank with fresh petrol.
Still no sign of starting.
2: Tried to give the carburettor a strip-clean, then decided to fit completely new carb. No start.
3: Checked the spark plug and discovered "no spark". After seeing YouTube clip about this, decided to replace the ignition coil.
4: New ignition coil fitted; still no spark. Bought new spark plug - still no spark.
So please can anybody suggest what could be wrong. Have run out of what other faults might have caused this non-function. You advice would be very
welcome.
Bear in mind that gen had been running OK initially.
TIA

Oil level ok? Mine has a cut out switch linked to the oil level.

It may be marginally low and when pump picks up oil...

Faulty stop switch. Wire to stop switch rubbed through and grounding out. Flywheel woodruf key stripped. Is the new coil fitted correctly I had a
small engine where the distance between the coil and stator was set with a piece of paper between the two. If it was any further away no spark. Did
the coil come with new plug lead if not check continuity/replace.
Just a few thoughts hope you get it sorted.

Not clear from your post, but I'm guessing this is magneto ignition? most small generators are. If so, how sure are you there's no spark,
spark generated from a magneto can be pretty invisible unless viewed in relatively dim lighting. If it has a spark, but won't run then I'd
suspect woodruff key as mentioned above as that effectively screws the timing up
If there is definitely no spark, & you've already replaced the coil & HT lead, then most likely the magneto is grounded either
thro' the stop wire/switch or elsewhere
Can you find a manual for it online, there is usually a "troubleshooter" - working thro' it in a methodical manner usually reaps
rewards, flitting from one guess to another like a butterfly on speed generally does not ................
Hope you get it sorted

Bigheppy & russbost - Thanks for your additional thoughts on this very irritating problem. I'll check out the "kill" switch
connections and wiring tomorrow. (After checking the oil level).

Thanks again to All for your advice. Could see no spark, even in dark shadow conditions. So, in sheer desperation, I reassembled everything back
together, with the new parts, gave the starter cord a pull, and eventually it fired up  !!
All I have to do now - reset the idle and load-running speeds. Back to YouTube again!
