Hi all from beautiful Budapest, Hungary

We are on back to back river trips with a bunch of West coast GMCers. Just landed in Budapest after boarding in Bucharest, Romania on the Danube a bit over a week ago with Nick and Donna Roenick and Donald and Billie Guttman. We will be joined on the next segment by a whole bunch of GMCers including Jim and Judy Hupy and Manny and Deo Trovao.

If anyone you know is attracted by the siren song of socialism I recommend a trip to the former Soviet countries in Eastern Europe to see how well that worked out for them.

Even a continent away I would like to recommend to everyone struggling with an Onan to purchase a Pertronics magnetic ignition system to eliminate spark issues and a propane conversion to eliminate fuel issues. I know a bunch of the "conventional" wisdom is that we don't carry enough propane (not true from my testing) so the kit I designed and discussed at GMCWS last October (download the presentation from their web site) allows you to switch between propane and gasoline at the flip of one toggle switch.

Once you do those two things, unless your Onan has a rod sticking out the side, it will almost certainly start quickly, run smoothly no matter the load and outlast you and the next dozen owners combined.

Our vendors sell the Gary Bovee Pertronics kit for a bit over $100 and the special GMC kit that allows it to run off propane or gasoline is available from uscarb.com. Some of our GMC vendors may also carry that kit. Sells for around $250 to $300 depending on whether you use 1/2" or 3/4" hose from the tank to the Onan. All my testing and design work was done using 1/2" hose and that seems to work well in our application even though the design books say you should use 3/4" hose for a run of that length and that load.

No, I get no kickback or payment on any kind from anyone from either of these.

It doesn't matter how your Onan is wired or whether your board works or not. If you can get 12vdc to the positive post on the coil it will likely work unless you have a bad coil (rare). That or a bad Pertronics module (rarer still) is about the only thing that will stop you.

These two easy to install kits are way cheaper and way easier than trying to buy and fit in another brand or model generator.

Now back to the great Hungarian beer........
