I have an Autovilla with a CU2000 engine that has recently has the top end rebuilt. In the process of trying to slowly run the engine in, it has stalled and failed to restart after doing about 15km's. The first time after basic troubleshooting, I disconnected the electrical connectors on the automatic chokes and it started up again. The second time, when needing to use higher revs to reverse up an incline, it stalled and restarted twice but not the third.
Both times the restart also only came after the engine has significantly cooled. When warm, it seems to me to be idling too high. So, I'm hoping for advice on the following -
1) It has an electric fuel pump installed and when disconnecting the pipes at the carbs to troubleshoot, and turning the pump on it seems to me to be providing perhaps too much fuel. Could the electric fuel pump be the weong thing for these carbs? Or, can this be solved by having the carbs set correctly?
2) I know the Autovilla is very heavy but I was expecting more from this 2L engine. Feels even more underpowered than expected. Still sticking to slow speed run in but at the moment I would doubt it would make more than 90 km/h on the highway and modest hills 50km/h seems to be the max. As the run in continues and it "loosens up", is it possible the power would increase?
3) For the run in, the first 10km from my house in any direction (except the N2) is quite hilly. For the run in, I need to choose between slower speeds but high revs or the flatter N2 but higher speeds. Is 20kms at a time on these hilly roads a problem for the run in?
Thanks for and advice/comments you can offer.
