That's pretty cool. I remember using a stopwatch and an electric clock with a second hand and adjusting the frequency up or down until I got it to agree with the stopwatch. Who needs those fancy meters! A long time ago Voltmeters didn't have a frequency display. And if you didn't have a Voltmeter you could just use the "bright light method" kind of like yep that light looks bright enough for me! These youngsters don't know how good they have it nowadays.

No problem sir. I appreciate your post. 

Thanks RCA. I obviously misunderstood something that wasn't even there. I did re-word it though to make it a better post. I remember a couple years back when one of my neighbors stopped by to ask why I run my house on generator power once a month for 1 hour. He told me He didn't think it was necessary to have a generator for his house. Oh well.   

Obviously my post was offensive so I'll just delete it.

The satisfaction of having the Changfa come on line and being the only house for miles with power was a great feeling but the smile on my wife's face was priceless. Being prepared is what it's all about. I think it's a common trait well all share here.   

What Compression ratio are those Cummins running? There is a company out at Cedar Hills Landfill (King County DNR) that are getting ready to run 32 converted 6 cyl Detroit's on landfill gas that will pump the refined gas into the Pipeline. 

You know I have never seen any commercial duel fuel (Diesel/LPG) units. The only duel fuel that I know of are Nat Gas/LPG. All of the units we have are Ford, Chevy and Mitsubishi. The Fords are the V-10,V-6, 460cu and the inline 4cyl. The Chevy's are the 454, 350 and as yet to be seen LS1. The Mitsubishi's are just junk. The specs on all of these have normal compression ratios of an automotive/truck engine. I think the 195's compression ratio would be way to high. Cat makes a 3406, 3408, 3412, 3508, 3512 and 3516 in Nat Gas form. The compression ratios on those are down to around 8.5-1. As crazy as this idea is I would like to see someone convert a 195 to Nat gas or LPG. I think it would be very quiet and smooth running. Of course the HP would go from 12 down to 5-6hp. I'm not sure what effect a 17:1 compression ratio would have on this engine. I'll have to add this project to the unending list of crazy things I want to do.

I don't know why but this popped into my head the other day. Take a 195, cnc cut a spacer plate to lower the compression ratio down to 8.5-1. Take out the fuel pump and injector and in it's place a set of points like a Kohler. Machine an adapter to sink a spark plug down into the head and install an Impco LPG carb. Wonder how smooth and quiet it would be.

Okay, I'm breathing through a rag soaked in Diesel, I'll be okay now.

To many service calls working on Nat gas and LP Generators will do that to ya.

After spending about $500.00 on 3 different starters that were "guaranteed" to be the right one (which none were) I gave up and rebuilt the original one using parts from the 3 I purchased. It was an expensive lesson for sure. I still have hopes of finding a GM/Ford starter that will work, it's out there somewhere. My dream is to be able to walk into NAPA and get one off the shelf.

Wow this is like walking into a new Changfa Store filled with new engines and shelves stocked with parts. This is cool. WOW. I like it.
