Last week I posted about how I was having heat soak problems on my Autolite 2100. I removed the airhorn and the fuel bowl was nearly dry. I assume that was because the bowl was nearly dry, and it had to fill back up as well as wait for the fuel line to fill back up.I did a search as well as asked last week and came up with these solutions. What do you all think?
1) Insulate the steel fuel line from pump to carb.
2) Ensure that fuel is flowing well enough (Replace filter, check pump for flow, clean needle/seat)
3) Use a less oxygenated fuel (Does that mean lover octane? I can run 87 with no problems but usually "treat" my car to more)
4) Add a small amount of diesel fuel or MM oil to each tank of gas to decrease its volitility and increase it's boiling point.
5) Move from the aluminum spacer to a phenilic spacer, and add heat sheilds to the carb.
I plan on doing a combo of these options (actually 1-4). My car has only had the heat soak problem this month, in the hot July heat. I would run the car to operating temprature, and then park. When I came back between 20 minutes and 2 hours later, the car would be flooded and would be a hard start, and when it finally would start, it would shoot out a nice cloud of black smoke. Then, if I let it sit over night, it would fire right up, but then die and have to crank a moment to start up a second time.
Lastly, what should the curb idle speed be on a '68 289 2v? Fast idle speed? When the choke is on the gap between the plate and the body? Thanks!
