I guess if someone is in a pinch this would make for a great generator build in a couple hours or so. Love it.

Nice, finally a simple video, I'd like to see how your 15hp engine performs.

[@trickydicky6788]

Hopefully I should have the 15hp engine video up to view in the next couple of weeks. The engine should be here in the next couple of days.

I already did this, but I used direct coupling to the engine. I have a 2 stroke set up I've not yet finished.

Great setup there mate. That's what I am hoping to build. I have a horizontal shaft lawnmower engine, so the setup would be different to yours. I like the frame you made for it also. That has given me some ideas. I like all this sort of stuff. New follower. 👍👍👍

Thanks for your message, glad you found it useful.

Hi, this was set up to test the alternator to make sure it was working. The plan is at some point to modify the alternator to put out a higher voltage, to use for a different purpose.

ahh i see. davidpoz made a few videos with engines and alternators and dc motors similar to what you're going to do.

Hi, a suggestion, go to a motorcycle wreakers and get a motorcycle engine. You could get a two or even a four cylinder. Much better than those shonky Chinese pull start engines. Better still get a smashed bike. You will get the engine, exhaust, fuel system, ignition system, starter (beats pulling a rope) and a whole bunch of other bits that may be helpful. Front end and frame might be bent but your going to be pulling it apart not riding it. It will be much more powerful and reliable than a Chinese lawn mower. Sound more pleasant too.

[@trickydicky6788]

You are right of course, but that would be expensive.

[@Hydrogenblonde]

@@trickydicky6788 maybe, I bought a engine from a wreckers, it was a twin cylinder 250cc Suzuki, 26 hp. It was a bare engine. I had to make up ignition, exhaust, fuel system and repair some minor damage. It cost $180. It depends on how much work you can do yourself.

[@trickydicky6788]

Something also to remember a motorcycle engine needs to be cooled, under normal conditions a motorcycle would be moving through the air when the revs are up.

[@Hydrogenblonde]

@@trickydicky6788 yes you must have a fan.

[@dantheman6698]

that works fine but you're putting too much load on it. its a 2.6kw alternator on a 2.6kw engine, its never going to work with a 3kw load tester. what are you even trying to power with it ? you give no info on what its for?

[@trickydicky6788]

I sent you a reply, but it went to the top of the list.
