Re: Overflowing Fuel

Hmm....in the last 50 years or so, I've owned 60 some automobiles and motorcycles that used carburetors. I currently have 6 older cars with 16 carbs between them. I've always checked the metal floats for fuel ingress as everything I read said to do so. And yet I've never experienced a defective/leak...

Re: Automatic air bleed valve.

While I wouldn't say it's not worthwhile, I've had 3 E types (2 3.8, and 1 4.2) and never had an issue with overheating or feeling the need to bleed the last few cc's of air (if in fact it exists) from the intake manifold. Quite possibly it would have value on a competition engine, something about w...

Re: tach wire generator wire placement? (pic included)

There is a fix for under reading AC tachs-and that is to send it off (to Mike Eck in the US-see the US JagLovers Forum) to be modified to use the tach generator signal as a pulse input. The mod is an internal circuit board, and requires a switched +12v wire to be added. Not other wiring mods, so it ...

Re: Over torqued head nuts

A permanent elongation of the stud would be accompanied by a reduction in diameter, however slight. But how did that reduction manifest itself? A consistent reduction along the entire shaft? Near the center of the stud? A reduction of the root diameter of one of the threads? In several places along ...

Re: Wheel/tire selection, help needed

I run the MWS 6.5" wheels with Michelin XWX 205/70-15", with no clearance issues at all. Rear bump rubbers have been reversed, but not sure that was required. MWS have done their homework on proper backspacing for this application. You do have to have the rear of the car fully lifted to fit/remove t...

If I understand your question, yes, the throttle plates can be tricky to get exactly synchronized due to the inherent free play in the individual drop links from the throttle shaft to carbs. B...

Re: Tappet Guide Hold Downs?

If the car is low miles and if the engine has never been seriously overheated then I wouldn't trouble myself with installing the hold down kit. But if the head needs to come off for any reason, or perhaps when it's time to set cam clearance (i.e. cams need to come out) then I might install the kits....

Re: Short skirts!

Mark,

The oft mentioned torque dip can occur with those awful tubular manifolds with the large fan shaped 3 into 1 collectors on an otherwise stock engine. With the build you are planning it shouldn't be an issue.

Re: revs at 2,000 rpm....HELP. 67 fhc

positive crankcase ??, do not know what to check with that There is no positive crankcase ventilation system with the 6 cylinder engines. Just a crankcase breather that vents into the airbox, so not a possible cause here. Also, incorrect timing cannot cause such an 1800 rpm idle by itself. I would ...

Re: revs at 2,000 rpm....HELP. 67 fhc

Well, obviously you're getting extra air from somewhere. An incorrect float level won't cause this. You've checked out all the obvious locations like spindle shafts with propane/starter fluid/etc, yes? And you are clear about the difference between the slow running screws vs the mixture screws, yes?...

Disconnected, and plug the vacuum line to the engine when setting timing at idle. Connected when checking timing advance at various rpms. From a timing standpoint, there is nothing special about the XK engine, other than #1 plug is the one closest to the firewall. Keep that in mind should you ever c...

Re: 4.2 engine question on dwell and vacume

Dwell is a function of the lobe separation in the distributor and the shape of the lobe (along with point gap of course), and is pretty uniform across makes, based on the cylinder count. Dwell setting for any 6 cylinder engine should get you close enough, so should be in the 30-35 degrees range. And...

Re: Complete interior

Patina in interiors can be a wonderful thing if there are no split seams or major abrasions, even if the rest of the car is pristine. Adds emotion and time depth to the machine. It's only original once. Why not keep it original for awhile, just cleaned and hydrated. You can always do it later if you...
