OK, On the manual I have printed out I was reading the wrong block. There are different versions of the engine where the PTO can be either the crank or the camshaft. For the PTO at the crank it is indeed 1200 RPM under a no-load condition. Dan, What is your engagement RPM? I was thinking going aroun...

rover: would you do direct drive or have a CVT drive a gear reduction? I was designing mine on paper and I was thinking a CVT might be good for the occasional steep hill where I live. I also know from looking at electric motor PDF's that there is a point where it is most efficient. So, I would try a...

Single cylinder engine idle speeds?

Any ways, as I was looking through through the manual of my lowly 6HP Yanclone, I can not seem to find an actual idle speed. I know it was pretty much designed to run out at 3600 all the time.

The Yanmar manual points to 600RPM for their version of this engine.

Sound right?

Ahhh...

That's also a very good idea. I kinda thought about something like that but I did not think to mount it so rearward. But, I like it! Definitely solves many problems about the chain and the swing arm and more room for the batteries!

If you do a search for electric mopeds and the like you will find electric hubs that can be spoked to a rim. I myself was thinking of using such a product for an electric motorcycle. You would have more room for a battery and a simpler drive train. But, I have not seen one that can attain highway sp...

Here is a company that does conversions and has kits and parts: http://www.electroauto.com/ Those PMA look very promising however according to their website those vlaues are a under a no-load/peak condition. So, those values will be considerably less. RMS would take any of those values X .707 which ...

I know the response is dated, but...

rover, I think this idea is fairly simple. All you do is power a generator via your diesel engine and then that generator powers the motors. However, I do not see how this will be more efficient as you will be carrying a lot more weight around. Plus, the inherent complexity of this setup. I have sta...

Any ways, I have been really thinking about this idea. I found an online calculator and my Yan-clone has a static compression ratio of 19.5 and a dynamic compression ratio of 16.5. And, with 3PSI of boost the dynamic compression ratio increased to about 19.4 IIRC. I also calculated the fuel injectio...

Do you think it would be possible to modify the existing plunger and take out the material above the idle line? Or, does that entire "fuel helix" have to be calculated from the start?

Any progress?

The reason I ask is that I was thinking of a smog pump to be used as a chain/belt driven supercharger. I had heard rumors of this from the days of yore. But, with the advent of YouTube and the internet in general I have found people who have used them. I have a smaller clone diesel but looking at th...

Well, you would have to rebuild the pump at the very least just to install the new plunger.

And, that's after you modify the plunger.

I'll do it if I can find a spare plunger for my current clone.

Is that all that is required, just create that channel in the plunger?

Hrmmm... The only thing I can think of would be to run one of those dual-ended cables for a dual-carb bike, like for an old Honda Twin. And have each one control the engine speed and fuel delivery. And try and adjust for the best. But, these engine were designed to be turned on and run at 3000RPM or...

Dan, How long does it smoke? If it just smokes as you get off idle then I would nto worry about it. The only way you could really avoid this is with a more advanced diesel system. Like a common rail diesel with electronic injection control. The three diesels that my parents farm has: a big Kubota tr...
