I just used Chris Foley's excellent rebuild kit on my leaky MPS. After removing the spider webs and varnish it all went together nicely. Chris gave me some great tips on getting an initial set. I think it is there but I don't have any experience with how a well tuned djet 2.0 914 should run. I suspect there is probably 150k or so on this engine although it could be lower, I doubt higher unless it was cared for very very well. Impossible to know with the dead odometer. Compression is great on all cylinders with no variability.
I took a little video of a drive, start up, corners, and two pulls to 60 (of various quality). After the first 40 seconds I opened my sliding rear window so you can hear the engine sounds better. https://youtu.be/Fi4vFCWhlCw |

Just an update on this. No matter how I fiddled with the rebuilt MPS or the fuel I couldn't richen the part throttle mix. So... Started thinking about trigger points going bad. My actual points were not looking too hot either. Figured now was the time to go for the 123injection distributor. Bought one off of tangerine racing and popped that in. After dealing with a busted oil hose (just plugged it for the moment), I started adjusting the MPS again. Sure enough, the MPS makes a big difference in afr now. I put the fuel pressure back at 29 before I started.
After a couple days of experimenting I have gone from this To this |
