Changfa clone?

[WGB]

Hey Bob are these any good?
Looking at the 7 hp engine.
I see they run over 2000 RPM can they be run slower at HP loss?

to be honest i know nothing about carrol stream engine's, or which manufacture he uses.

having said that, the little 3.3 hp engine is pretty cool, and the 7,7hp 2600rpm electric start
is an interesting engine

i would expect that it can run slower at reduced output, but how much slower i don't know
how slow do you want it to go?

it might make it down to 1800 and still run fairly smoothly, but i would expect maybe 5 hp at
that speed.

not sure if that is much help or not?

Thanks, what speed do your Changfas run?

[mobile_bob]

the 195's are rated at 2000rpm, but i run mine at 1800 for ST power and around 1200rpm
for low output alternator power and for refrigeration compressor use.

Thanks
Just read your post, I'll look at all the things you worked on.
And I'll put a magnet in the crankcase like Veggie suggested.

Got a call from the trucking company, my engine will be here Monday afternoon.

I came so close to getting the 3.3 hp, what a cute little diesel that must be, it was pretty cheap but hasn't been relisted. I need to start balancing my gas engine collection with diesel engines    I may still if you have good luck with your engine from them.

[WGB]

I got the engine.
Take a look.
Tell me what I have to do!

7.7HP changfa?  That's BIG, I thought it looked like 13hp brother.

What does 3.3HP in size compared to this?

Cheers, Wizard

That's a nice looking unit.
What generator head are you planning on driving with it?

Its a thing of beauty! Hope the inside is as good.

Thought I would use a Harbor Freight at the start of the project 299.99
.
Now I'm thinking of a Voltmaster* like Veggies or a PM like George's from utterpower.

Any input would be welcome.

I think I want as good and clean power as possible out of this generator.

Also I'd like to have a 12 volt alternator, and air compressor with an electric clutch. I would only use air or electric not both, and probable have separate tank.

Anybody do a compressor, any ideas?

Thanks
Bill
