SC30008KAF...very nice machine.

Actually, complying with EPA regulations has made a difference over the years. The main jets are smaller so cold running can be a problem. However, after it warms up for a minute or two, it should run properly.

Manufacturers always have a disclaimer of + or - 5%. It should be within that margin.

If choking it a bit smooths it out, the main jet in the carburetor may have debris in it. Was this machine bought from a dealer's stock? Sometimes machines are run when they're received, and if stabilized fuel wasn't used, and the machine sat for a couple of months, you may have a bit of varnish in the carb. If it were me, and the choke smooths it, I'd run a dose of fuel injector cleaner through it and see if it runs better.

Does choking it a tiny bit stop it from hunting?

Looks like they only use that on the diesel engines. It might keep the key from getting beat up.

Nigel, the only hole in your theory is the burner. At less than full speed, the 12 volt charging system won't produce enough to keep up with a burner. Likewise, a generator spinning less than 3400 won't produce 120 volts @ 60 Hz. Fluctuating the engine speed would compromise the electrical components of the burner.

The governed rpm is 3,600. This will allow a drop to 3,400 under load. It doesn't require much throttle to maintain 3,600 without a load. Imagine the throttle to run a car at 2,000 rpm sitting in park, then again going up a steep grade. Honda doesn't want the governor to "floor it" just to do its job.

That's exactly it. And the fact that the governor travel is close to 100% WOT. I started building some homeowner type pressure washers years ago using Honda GC engines. I had to take my prototype for Honda testing. It included cylinder temp, oil temp, and governor travel. 3/4 WOT was what Honda deemed acceptable to keep the engine under warranty. (WOT = Wide open throttle)

I prefer the formula: [(GPM X PSI) / 1450] X 1.5

Blue Goodyear Neptune single wire is all I could find in 1/2", 150'. Rated for 3,000 PSI. Your cost - $298.75 plus shipping.

I'll check with my supplier and see if I can get 1/2" non marking in 150' lengths.

Absolutely. Especially at higher volumes like yours. There's a lot less back pressure in a 1/2" hose. Let's say you want to run 200'. Make the first 150' 1/2" hose and the last 50' 3/8" for ease of handling.

High volume guns are available, but they ain't cheap. http://www.suttner.com/products/Details.cfm?PID=168&CID=5 $175.40 http://www.suttner.com/products/Details.cfm?PID=169&CID=5 $215.76

Either drop down 1 more size on the injector or install what you've got after the first 100' of hose.

Usually solid stainless steel Not really. The oversized pumps cost more money, so they stick to the manufacturers' ratings. Larger pumps would cost more money, and you know most shop price. You wouldn't want to slow the pump much, as they are designed to splash a certain amount of oil around in the crankcase at the specified rpms. Slowing the pump too much may cause a lack of proper lubrication. Many of the UHP pumps I've seen have oiler cups on the piston rod so they don't rely on a "splash" lubrication system as much.

That's true. All the UHP blasters use a small diameter piston (1" - 1 1/2"), but a 4" stroke and 1,000 rpms or less, and pump 20 gpm @20,000 psi.

Yeah, act like you're not old enough to remember...:D

Page 30 of the catalog you linked to has the equivalent of the TS2021 (the WS202) that is rated for 2,900 psi. I guess General decided they could sell more by rating it for 3,500? Who knows...but, yes, other than some differences in appearance, the mechanicals are the same.

So, I buy a pallet of T1011's at a lower price and slap a HP5535 sticker on it. Just for clarification, I don't relabel the pumps, i buy them like that.

So true...

That's because the pump is not sanctioned or authorized by General. I'm only guessing here, but I'm thinking the name change happened due to copyright infringement. Mark, if you ordered a TS2021, you didn't get what you paid for.

Same specs, different warranty. The HP5535 is a relabeled pump made by General. You'll have to go back to the vendor who sold it for warranty consideration rather than going to General. The HP5535 was formerly known as the TS2021B.

What brand are you using, Scott? I use nothing but Gates. I have tried Aeroquip, Imperial Eastman, and a Chinese equivalent to the Gates, but nothing works as well.
