  1. I don’t think it’s vapor lock. Has the idle mixture been set properly? Sounds like it may be rich, loading up then having to clear.
  2. Must not be a choke sticking shut if the choke plate is open, the bottom plate is the throttle, it should be closed at idle. Oh well, it was worth checking. Beautiful car!
  3. I don't know what kind of choke your carb has but if it is automatic it may be closing the choke when it shouldn't. If the choke isn't manual make sure it is functioning and adjusted correctly.
  4. There isn't anything special about the dimensions of the stands, I just cut the 4x4's to allow the maximum number of pieces from the stock I had on hand. In my case that worked out to 10".
  5. I put work stands where the possibility of the car falling on me is minimized. The most substantial component in our cars is the frame and that's where my work stands are located. If a suspension member needs to be "de-drooped" I use the floor jack to move the suspension back into road position. I trust these work stands with my life when they are supporting the frame.
  6. Knowledge is power! I used to tell my students that if you are willing to spend time reading and researching there isn't anything you can't accomplish in nearly any subject. I realize there are those for whom reading is a chore due to disabilities but there isn't any excuse for lack of effort by those who refuse to use their God-given abilities. And this is why some forum old-timers (and not just on this forum) have patience meters reading down in the red.
  7. Excellent reminder for all of us, thanks! I realize just throwing a question out to the forum is much easier than doing some homework. Many folks (most?) just hate doing homework and prefer a quick answer (I spent fourteen years standing at the front of a classroom facing impatient pupils....). But it is amazing how much information is available on nearly any subject with minimal effort spent searching. Yes, forum search engines are often not well designed so I always go to Google. To search this forum with Google do the following: site:p15-d24.com then your inquiry such as how often to change oil That particular inquiry instantly returned 18 threads on the subject of oil and filter change intervals. I have to admit the old teacher in me doesn't have a lot of patience for folks who refuse to do homework instead of trying to educate themselves before seeking help. Guess it's a rebellion against the instant gratification component of our culture. Doing some basic research has often saved me from asking a question that has been asked who knows how many times previously. But if a search doesn't return a good answer......ask!
  8. Here are a couple of videos that should be interesting for those who are considering driving our old cars at modern speeds on congested highways. I know, I know......live life to the fullest, but still.........these cars were designed for a vastly different day and age. https://www.youtube.com/watch?v=Tlvl8fXuuVg
  9. Off topic but just wondering what happened to MarcDesoto........
  10. That is definitely the best method since you don't have the original generator pulley and you want a belt a little shorter than stock.
  11. The valve isn't insulated, I put some fuel hose on the handle so it won't hurt my fingers as much when I turn it, it is quite stiff to turn. No way am I going to tempt fate by unnecessarily breaking off the old valve in the head, then messing up the threads, then having to remove the head from a low-mileage, perfectly running engine, then, whatever. There are winter projects and there are fool's errands....... With three vintage cars (and an airplane) I keep in daily driver condition there are plenty of maintenance jobs to keep me busy, currently in the process of putting a new exhaust on the TR6 after installing new differential, driveshaft and axles.
  12. Connect the 12v battery directly to the starter and DON'T use the car's starter button and it won't matter if lights, etc are on or off because they won't see 12v.
  13. I don't want to belabor this topic but maybe it is educational to some. What you are describing with bridging the battery and starter terminals on the solenoid is not the same technique I've described. Unless I'm missing something you are connecting the 6v battery to 12v when the jumper cables are connected to the battery. I don't know if this is harmful to the 6v battery but what I've described doesn't have this risk since the 6v battery never sees 12v. Or maybe you are disconnecting the solenoid from the 6v battery? If I have misunderstood what you are describing please feel free to elaborate further.
  14. Not easy to replace when it has seized in the head like the one on my P15. Fortunately it is stuck "open" so all I had to do was install an inline valve in one of the heater hoses, didn't want to risk breaking off the old valve in the head. It is a manual valve, I open it late fall and close it late spring. The under-dash dealer-installed heater in my car is very effective, the fan still works nicely.
  15. Good point. Or you could clip the positive lead to the starter terminal then make contact with the ground lead on the engine block to spin the starter. The polarity of the jump battery doesn't actually matter since no jump voltage is being fed into the car, just the starter and it doesn't care about polarity. Once again.....DO NOT USE THE STARTER BUTTON in the car! Doing so will back feed jump voltage into the car through the starter solenoid. If this concept is confusing, spend some time with the wiring diagram to see how this is a safe procedure when applied properly.
  16. The solenoid can't back feed if the starter button circuit isn't activated. I'm describing what you can do in a pinch if the only jumper battery available is 12v. Our 6v cars can be jump started with 12v if the correct procedure is used and no harm will come to the car's electrics.
  17. Some mis-information is being passed on about this topic. If the positive jumper cable is only touched to the big starter terminal to make the starter spin, it makes no difference if lights, radio, etc are turned on, no jumper voltage will go to them. Only the starter will see 12v. The starter switch in the car IS NOT USED!!!!! Just turn on the ignition so the coil sees its regular 6v. Think about it.
  18. Nothing radical about it, just need basic understanding of how the car is wired. There is no risk to the car if done properly.
  19. Yes, if the 6v battery has enough juice to fire the coil. Connect the ground of the 12v jump battery to the engine block, turn on the ignition switch, and touch the positive jumper to JUST the terminal of the starter that has the big cable. That will provide 12v to the starter but not the rest of the vehicle. The starter will spin the correct direction regardless of polarity. As soon the the engine catches, remove the positive jumper from the starter. I have jumper cables in my tool bag in the trunk of the P15.
  20. Yes. Notice how the sides of the valve body are flat and parallel which makes it possible to use a wrench to unscrew the entire valve out of the block. Well....possible if the threads aren't seized in the block and the valve doesn't break off in the block....
  21. Thought I would be a nice guy and post the shock part numbers in the Tech section of the forum but couldn't find a way for a non-admin to start a new thread.
  22. But when you consider the performance gain due to reduced vehicle weight they are a bargain! ?
  23. The #1 wire MUST be where the rotor is pointing when #1 cylinder is TDC on the compression stroke. Proceed from there with the correct firing order on the cap. Changing plug wire position on your very well running truck will transition it to non-running.... Your oil pump is installed 180 degrees from standard as it is on my very well running P15. Don't mess with it.
  24. Congrats on your new ride! It looks great and reminds me of the U-Haul ride my "new" '48 took to my shop. These are great cars to work on and will give you many miles of enjoyable cruising. You can change your signature now. The P15 has the better butt......... ?
