Name is Harold. I have a VERY unique problem, and, no Honda Dealer can or is willing to try to help me, so far.
I have the Honda GX620 20 HP V-twin engine, on my sawmill. One day, as I was just finishing a cut, and started to gig back the sawhead, the engine gave a quick bang-bang and coasted to a stop. I used to be pretty good at diagnosing and fixing most mechanical things. Sight and hearing are getting worn out.
After doing a lot of experimenting, including spark check, there was no spark to either cylinder. Coils "Looked" OK
While turning the flywheel, I noticed 2 shallow depressions on the outside edge, and one had a brass machine screw in it. So, while looking a little harder with a flashlight, I found a piece of a magnet. Looked some more and found 3 more pieces, + a sheet metal curved bar and a white plastic curved part ???
Realizing this was the ignition magnet, I tried online to find one. All I was told, is, they aren't listed in the parts directory, OR, I could buy a NEW FLYWHEEL, for $600 and some dollars, shipped in from Japan.
SO, I have been looking online in Magnet sales websites, and there is nothing I can find that I could make something with.
Frustrated, I went to the shop, had some magnetite and some good epoxy, and made all the parts of the busted magnet, fit. I installed them after waiting 2 days, to insure the epoxy was cured. The brass machine screw must have vibrated loose, or something, because the screw head would pass through the hole in the magnet. I smeared exoxy all around the hole, and waited 2 more days to see if the engine would run. It did, for 5 seconds, then, the magnet blew apart. Now, I have an engine that needs that small curved magnet with a centered mounting hole.
Anyone here have any ideas or suggestions ??
Parts down here, simply don't exist for these type engines. Sorry if I came on a little strong, but, I NEED the sawmill running, and, Honda support doesn't care.
Thanks for ANY helpful ideas. Harold in CR
