So once the generators are synced the resistance of the generator head to changes in engine speed will keep the generators synced? Or are we better off w/ a fancy inverter & the custom open source fuel injector system w/ twin computer control?

If the timing of the AC waveform being produced by one generator starts to slightly lead or lag the timing of the other generator, it creates an additional mechanical load on both generators that tends to pull them back into synchronization. However, if the timing changes faster than either generator's engine can adjust speed to compensate for the extra mechanical load, it can cause them to lose synchronization entirely - at which point they "fight" each other until something blows. |

If you read more closely, I think you will conclude we're educating each other and exposing and explaining, to some folks --new concepts. No one knowledgeable has suggested ---in a practical sense, syncing 2 $90 gennies, although it would be an experiment that could result in much knowledge gained to someone who has the resources and motivation to try. |

My well pump takes 30A @ 220V plus the huge starting surge. While I can run everything else on a much smaller single unit, I would need to parallel another 6500W unit to handle that load. Learning to sync gennys via bulb test is a good skill to learn and practice if your are going to have to do it for real. Learning on cheap low HP units (so a slightly out of sync switch over won't cause a big fight) is a very practical plan.
To feed my house I kill the well pump breaker at the meter box, then on inside panel I kill the kitchen appliances and furnace blower ( I have both a built in mega microwave and a low power counter top one I use on the genny) I have a propane wall heater that can provide about 85% of the needed heat (it doesn't quite make it to the far corners of the building). Sticking with bottled water, and I keep a huge amount on hand for flushing, dishes etc. I can keep the frige, internet and a few PC's, TV, lights running on a 4.5Kw genny at about 70% load. Kill TV and extra PC's I can run the furnace blower. A few times when lazy I have run the internet, 2 laptops, and a few CFL's on the HF baby blue and not bothered with the "Medium" genny. I keep a full 5 gal of pre-mix in the shop to feed the genny, weed wackers and a few other misc 2-stroke toys. I will be looking into that Champion 1400/1800 unit. I have been lucky in that while the power drops out here rather often its rarely out more than 12hrs at a time and worse case was about 2 days. The 4.5Kw would eat up my stock in a week (never mind there is 400gal in the motorhome tanks... people forget those suckers make great fuel trucks  ) I was told there was a time when the power was out 11 days. Ideally I'd love to be prepped for 30 days.

Here's mine, got it yesterday and have run it 5 hours so far.
I changed the plug, locktited some screws, used my own foam air filter which fits better than the tiny loose foam filter it came with... I haven't used any load more than 500 watts yet. The only problem I've encountered is the spark plug coil contact getting stuck on the plug. If you need spares, amazon and ebay have parts for the ET650 which is the Yamaha generator this one is cloned from. I'm liking it a lot for the money. I don't know why I bought it other than it was so cheap I couldn't help myself. I already have 2 other new gen sets, but I can't carry them around. 
Loose foam filter with big gaps... 
Edit: After 2 days, and 6 hours of break in, I noticed a 2 inch diameter oil spot on my patio: there is blow by at the spark plug interface with the head. The machining there shows chatter and galling. It's not flat, and leaks even with the plug torqued down. So I took it back and exchanged it for a new one, which in 4.5 hours works just as well, starting after 3 pulls. So I still like it but quality is hit or miss. Thankfully the second one seems great. The head is machined much better and is flush, even though it was serial numbered only 34 further down the line. It has more stickers on it. No oil at the spark plug, which I didn't bother to change. Cylinder head of first Generator:

According to internet lore, the white version uses mesh that's too fine to feed reliably without a fuel pump - which is why the red version is recommended instead. |

I am in to parallel two units, but I won't be able to do it until summer's end.
I already have one unit from the Ethanol/Charcoal lighter fluid thread that backbencher talked about, so if we start a fund going for a second unit and some gas I am game when my days get longer. O-scope and meters already are on hand so no other test equipment will be needed. Watched 150 KVA UPS units smoke, so a 600 watt generator will be fun. I think they are going to be too small to sync without being mechanically tied together though. The quality of the engine for a stable RPM and load recovery is just not there. PAR |

Update on my 2nd HF 900 watt generator: continuing the break in process mostly with a 500 watt lamp load: still chugging along perfectly after a total of about 15 hours of run time.
It sometimes has a screechy sound to it after a few hours, I took the recoil starter off and fiddled with it yesterday (nothing specific wrong) and it seems to be better today. I'm using 50:1 89 octane 100% ETOH free gas (BP Silver) (down from 40:1 mix). It starts on the 3rd pull or sooner. Original Xinhua spark plug. No oil leaking anywhere. So far so good. BTW I just got in a SuperGen Tent (regular size) which swallows this little generator up. It makes it a bit quieter, but the generator needs to be raised up a bit to be more effective. I measured the dbs with an ipad app: I get about 5 db reduction in sound levels at 23 feet. Not a big difference, but measurable, hardly worth using for a relatively quiet generator to begin will. I get as big a reduction in noise going from sitting on a concrete surface to a mulch or grass surface. I'm thinking about getting a piece of Quietbrace (about 9$ at HD for a 4x8 ft piece) to set it on and see if that helps, too. |

Since there isn't a crankcase that contains any oil, your "oil slick" would have to come from oil in the fuel.
Most likely culprit would be a leak in the fuel hose - very easy to fix. |

leak could also be the fuel cap. one of mine sloshed fuel like crazy i pulled the replaced the gasket with a thicker one and it fixed it. i never saw gas leaking but over a 10-15 min run the whole unit was greasy.

I have no idea on the correct terminology, so just follow along the best you can. The puddles under the unit were a very dark black. The housing for the piston was leaking somehow, possibly through the gasket. Make sense? |

Most PC power supplies are pretty beefy for 5 or 3 volts, but kind of wimpy on the 12 volt connections. A trolling motor could draw 20 amps at 12 volts, easily. |

I guess it's OK if you have a low-need battery that you'd kinda like to charge while you have the gen running for other stuff, but for much more than that I'd use a battery charger or inverter for higher output

What's the consensus on red vs blue?
I've got a blue one with about 50 hours on it that I can still return until October. (extended warranty) It has always had a bit of a rattle, but runs fine under load. I'd hate to return it and end up with a newer one that might have it's own issues. |

I think that they changed some screw/bolt sizes and there's something on the carb that is slightly 'improved' IIRC. My red cat has a slight 'marble in a glass jar' knock to it, but after 15 hours last year of break-in, I'm able to overlook that. I ran mine at 40:1 with the marine grade 2 stroke oil and it doesn't smoke and works pretty well. If your blue cat is working, I wouldn't worry about it. At $80, you can always pick up a red one and have a spare, without breaking the bank. Chris |
