Changfa Engines / Re: Do it Changfa Style

They really are amazing engines.
A few years ago I built a really nice Changfa 195 Generator which my neighbour bought from me.
Since then he has added only 2 hours of run time. He offered to sell it back to me for 25% less than he paid.
The problem is that I already have 4 in the garage. Hmmmm.... how could I hide this one if I bought it ?
Maybe if I painted it the same colour as my others she won't notice it ?  ::)

Veggie where are you located? And how much would you want for it lol

So now that the engine is running correctly, I'm going to turn my attention to building a frame, acquiring a gen head, and getting other accessories like a pulley. The frame and genny are pretty straight forward. I am a little confused on pulleys. I'm going with the same size and grooves as the the one that came stock on the engine based on Mr. Calder's advice. But are the shafts on the gen heads and the pulley's that go on them pretty universal on size and design? I've never done anything with pulleys and belts besides accessories on cars like alternators and they come with pulleys.

So I figured out the issue. There are many ways the notched part of the pump with the small teeth all around is fit into the pump, one common way is for the notches to be horizontal, the other is the have them vertical. Mine needed the notches to be vertical and for the plunger (inner piece with the diagonal cut across it) to have the cut section facing up. I had to try it in every common combination to find the correct configuration, because the manual states what order the pump goes together but not which way the plunger is supposed to be rotated to begin with. No problems now  ;D

She ran today! After struggling to take the fuel pump apart, I soaked it in diesel for 2 days, put on a thick glove and smashed it against a 2x4. It finally came loose after about 6 hits. I cleaned it, reassembled and the engine ran. The only problem was it wouldn’t turn off or idle down, so I shut off the fuel and it slowly wound down and died. I removed the pump again to try and figure it out but I am stumped. It seems that there is just very little control over the amount of fuel being pumped. I’m not sure if I need to adjust the ring with teeth on the inside of the pump or if it is defective.

Glort, if you were going to have extra parts for your 1115 on hand, what would you have? Also, do you know of good places to source parts for these Chinese diesels?

Here are the prices I was quoted:

8hp Single Cylinder Electric Start Diesel for $1,295
15hp Single Cylinder Electric Start Diesel for $1,895
22hp Single Cylinder Electric Start Diesel for $1,995
lead time is 10-12 weeks.
They had some 15 and 22 hp on site.

Any recommendations on ST head suppliers? Also, 38AC where did you get your pulley for the st side of your 1115 setup?

So I'm still stuck between a 7.5kw and 10kw head, either one would be plenty of power for me. If they are both rated at their respective power at 1800rpm, would it be better to pony up for the 10kw and run it at 1400-1500rpm (with WI and timing adjustment) if my main goal for this build is longevity? Also, here are some pics of the engine fresh out of the crate and mounted to a dolly for working on and moving around.

The crate arrived today! I will be cracking it open tomorrow and putting some pics up. Now I'm going to start looking for a generator head. I'm debating on whether to get a 7.5 or 10kw head. I plan on running it slower that the rated speed 1800rpm for normal operation and would love to run it slower. Would running the engine slow and turning a smaller head make a big difference in fuel consumption vs. the 10kw head?
