This morning I made an adjustment to the left rear brake pads ( the old hucks). When I had them relined I think the new pads were us a bit too thick. I have very little room for ajustment inwards. Guess I'll just have to wear them in a bit.
On another point I noticed that since I installed the new fuel pump my see thru fuel filter ahead of the carb is totally full of gas. That was never the case before! Maybe I won one battle....
Also this morning I hooked up my vacuum gage and tac so that they are on the inside of the cab.
OK, time to see how things are running!
Time is 11:52 - Start cold engine.
Choke all the way out and then quickly back in to about a 1" after she is running.
Vacuum 19"
RPM 1150
Temp Ambient 67degrees
After one minute slowly pushed choke to about a 1/2" out.
Vacuum 15-16"
RPM 475
Temp <100 degrees
Time is 11:56
Pushed the choke in all the way.
Vacuum 15-16"
RPM 600
Temp 130
Time is 12:00
Vacuum 16-16.5"
RPM 650
Temp 140
Time is 12:05
Vacuum is 17-17.5"
RPM 700
Temp 160
Ride time up the hill in my development.
Time 12:07
Went up hill in second gear. Vacuum drops to 6". Drove through the development and noticed that as I shifted gears the vacuum would drop to 6" (sometimes 0") and then climb to 22". Needle was all over the place.
To be honest with all you folks out there, I don't have a clue about what I am looking at!! Can some explain to me in laymans terms just what this engine vacuum means? Are the fluctuations I'm seeing normal or is it telling me something that is wrong? Its not only vacuum but timing and carburation. What would be the logical approach to getting these under control? Step one...step two...etc.
BTW, when I got back home (only drove her about a mile) I saw that the fuel filter was half empty. I think it will recharge itself after cool down. The other thing I noticed was what appeared to be gas on the outside of the carb. That kind of bother me. I surely don't want an engine fire!
Oh, you know what I just thought as I write this? I haven't checked the vacuum line from the dizzy to the carb. Gotta do that. And also Lucille is being run by a 216. Just an FYI in case no one knew.
I'm exhausted over here!!
Will the "Truck Gods" please help me??
