Better than no generator, generator. #4515854

I bought one of these little dudes at Harbor Freight about six weeks ago. It was about $88 with a coupon. Regular price is $109. Coupons on line.

https://www.harborfreight.com/900-max-st...carb-63025.html

It's a little 2 cycle 700 watt 2 HP machine. I use it at my boat dock to power the air pump for a boat lift. I was not sure if it would handle the load or especially the start up amps but it does well. Bears down yes but no problems at all.

Only 38 pounds so easy to carry.

I broke it in with no load for 20 minutes and when I start it now, I warm it up with no load for five minutes and then cool down with no load for 3. I burn 32/1 since it operates at very high load (don't flame me for not using the 50/1 recommended) and I use full synthetic FD rated 2 cycle oil.

Very quiet and seems well made.

Much better than no generator when you need one. It's like what they say about a .25 caliber pistol. "It's better than throwing rocks".

You will find that they only run 3600 rpm and will drip oil out of the muffler @ 32:1. I have over 300 hrs on mine and plan on 64:1 next time.

Probably will make nice anchor too. They had these stacked like a block wall at the south TX flea markets and there were several being used to power various items to show that they were working. It will probably run well past anybody's expected life cycle.

It might power a few lights while camping but not much more.

I never understood why people use more oil than recommended. I've worked on a number of these machines over the years where people did this.

Using a richer oil mixture than what is recommended can actually shorten the engine life. It often creates more carbon build-up which can break off and score the piston. Piston scoring on a 2 stroke engine means no compression, and it won't run or will only run very poorly. I have replaced numerous pistons/blocks because of this.

If you run a good name brand oil (I use Husqvarna semi-synthetic) and mix it at the proper ratio, you will not have any problems. Your engine will actually be cleaner inside as a result.

Not true on running rich oil mixtures. Hard carbon in these engines comes from running Boat oil in them. TCW3 oil.
Use a TC rated oil and you will have no problems.
I have run and tore down numerous two strokes and found that to be he case. I have also run 32:1 and 20:1 in small engines and had them last 20+ years without a teardown. Slobber out of the tailpipe is a good sign. Dry soot is bad.

Heard many good things about them. Red, White, Blue, and Green they all seem to be about the same and will run up to 1000 watts without issue. Plenty of power for most tasks.

For what they are it is hard to complain too much about them. I captured some wave forms on my scope from one of the older blue ones and posted it here last year. Nice when I need power on the farm to drive my dinky little air compressor, and listen to the old boombox during tractor maintenance.

I've had one for 6 years. It ran for almost 5 days when we lost power during a snowstorm.

Still starts up and runs fine.

700 Watts divided by 120 Volts = 5.8 Amps.


There's no such thing as:
Too big of a battery,
Too large of a gas tank,
or too loud of a horn,
or too bright headlights.

Not long ago I talked to a lawn care worker and they had one on their truck. He told me they use it on occasion when they need re-mote power for electric tools. He told me it does have a lot of hours on it and haven't had any problems.

Is it possible that the guys who run extra oil in their 2 cycle engines are the same guys that run thicker than factory engine oil in their vehicles? Just askin.

I've never seen boat oil run in engines up here. It likely isn't as big of an issue if you run decent oil, but many of these engines had the cheapest oil possible.

I also had a guy running regular motor oil mixed with fuel...
