John,

Why do you doubt it is "just a spring issue"?  Jeesh, if you want to tear into the engine to inspect the flyweights, be my guest.  But I don't see why you won't experiment with the spring first.  Maybe you like doing things the hard way?

Your absolutely are right! We will try reverting the spring first. Unfortunately, this engine is not in my shop, it's already in its final remote location. I just wanted to have as many things as possible to check.  I think it was a good choice to consider something else than just the spring. Having received many suggestions, we could now look at all of them, one after the other.

Will let all of you know of any progress. Thanks group!

JohnF13,

Thanks for your input. I think that you have a good point with the pin issue.

One other thing you could try - set the engine up for your nominal voltage/frequency (I recommend 61hz and about 120 volts, YMMV) at no or minimal load, apply your bigger load (say 3kw) and see what the the engine does - if it slows and will not get back up to speed, try manually opening the fuel rack to see if it will pick up.  If it does, then most likely your culprit is the governor mechanism.

This was tried already. Thanks
Manually opening the fuel rack and the engine picks up.
I know it's something with the governor, not an engine problem.
I doubt it is just a spring issue, Will check the weight pins and let you know.
Is it possible the weights are not well balanced?

Cheers!

Halfnuts,

I have a 4HP Mini-Petter and a 12HP Petteroid.
These are in stock ready to ship.

The picture is of the Mini-Petter, the 12HP is just the same but bigger.

t19,
Paint is not the problem.

fuddyduddy,
I don't think this has anything to do at all with the device being powered by the engine (In this case a generator head). You could be using the engine to drive a saw mill or other machine. The point is that speed it dropping by half when adding a small load on the engine and speed will double when taking the load off. Making it go faster than rated speed.

Thanks again

Hello fuddyduddy,

Thanks for your comments. My understanding is that this specific mod will improve the accuracy of the governor, specifically the response time. In the above case, the governor has no accuracy at all. Going from 150W to 1500W and the engine can't keep the speed. I'm not talking about the usual +/- 5% play in the governor response when dropping a large load.

Would you think it could be something with the governor weights not moving freely?

Cheers,

Pat

Hello Guys,

Engine: Standard Listeroids 6/1

This is the case, adjusting the governor with a 150W load for 120V at 600RPM works fine.
Adding a 1500W load and the engine can't keep the speed, voltage drops to 100V. It's even worst when adding up to 3000W.

Adjusting the governor for 600RPM at 1500W works fine, dropping back to 150W and engine over-speeds...

My first thought is that something could be stock in the governor weights but it might be a spring issue.

Your experience and comments are welcome. Maybe someone had the same before.

Thanks,

PAT

Petteroids / Mini-Petter gibkey puller
« on: June 13, 2006, 01:19:06 AM »
Thanks to the board admin for creating the Petteroids section. I think Mini-Petter should deserve to be better studied. The need for low power but heavy duty application exist! What else would you use to power a small water pump or a 2.5KW generator head for continuous duty?

I'm looking for your ideas about making the best gibkey puller for Mini-Petters.  I have a few 4HP in stock and I need to take the flywheel apart in order to ship them in two packages (150lbs UPS limit, these are 185lbs). Shipping with UPS is a lot easier and cheaper than common carriers, especially when a border has to be crossed....

As you know, the small size of the key, the minimal room around it and the fact that the shaft doesn't extend outside the flywheel make the task difficult to do in a clean way.

Thanks!

Pat

Hi Bob,

I wonder who makes the dipstick marks at the factory... probably the part-time student hired the day before :)

Do you check oil with the dipstick all the way up ( unscrewed position)?

Hi fattywagonman,

Very nice setup! I think Mini-Petters should deserve more attention.

What size engine is this?

Cheers!

It would be nice to have a Petteroids section on this forum. I like mini-Petters. They just look so cool!
