Art, Section 'K' in my shop manual has a drawing of the monocoque dimensions entitled "chassis alignment check".  I'm assuming this drawing was meant for body ...   12-06-2007 02:10 pm

Chris, I had a problem with 'sneezing' carbs when I used the double o-ring anti-popping spacer set-up and too rich of jets.  Replacing the o-rings with ...   12-04-2007 03:34 pm

Vern, Garry Kemp did the RHD 912 swap years ago and was my inspiration for the 910/907 hybrid I put into 13492.  My LHD modifications were ...   11-28-2007 07:16 pm

Arvin, The guy you want to contact is Jeff Schlemmer at Advanced Distributors jeff@advanceddistributors.com in Shakopee, MN 612-804-5543.  Jeff rebuilt my 45DM and has done work ...   11-27-2007 11:01 am

John, Very nicely done wiring diagram!  One wire I'm not seeing is the bypass to the ignition coil. From memory there is a large terminal with a ...   11-24-2007 12:53 pm

Dan, Under the heading of obvious mistakes I've made; did you roll the car back and forth? Not an issue for the rear but short ...   11-19-2007 05:37 pm

The dry-sump grafted to the engines in the picture appears to be an aftermarket design.  The factory Lotus unit was in a similar location, but ...   10-10-2007 10:59 am

A dry-sump alone will not solve the problem.  Lotus did build the 1979(?) Esprit with a factory dry-sump, but dropped it after one year.  Retrofitting a ...   10-07-2007 11:27 am

Greg, My suggestion is to block-off this vacuum port as most of the emissions control systems operated poorly when new and tend to make troubleshooting problems ...   10-05-2007 07:04 pm

The clutch fork may have 'clunked' off its pivot inside the bellhousing.  The t/o bearing spring and clutch cable may be holding it in place, ...   10-03-2007 05:50 pm

The tach behavior suggests the distributor inconsistantly firing (i.e. exactly what you've observed).  If it were a simple misfire meaning a plug, wire, or cap ...   09-27-2007 11:15 am

A nasty little fact about fiberglass is that it tends to warp with age.  A 30 year old timing cover will not fit without significant ...   09-25-2007 01:59 pm

Finally had a situation where I needed to get one of these hoses and document it here.  I started at my neighborhood auto parts store ...   09-21-2007 04:09 pm

Chris, who did your flares?  I have to do the same for my e-prod car and body-work is not my area of expertise.  suggestions? Judson ...   09-20-2007 08:42 pm

I'm hosting a get-together for the Atlanta area Austin Healey / Jensen Healey club this saturday.  Another post here for those of you not on ...   09-18-2007 12:17 pm

Colin, I find it's good practice just to run some 220 grit followed by 400 grit, etc. every time I have to do this kind of ...   09-04-2007 05:08 pm

Dan, There was an Excel variant with an Automatic.  Judson ...   09-03-2007 04:26 pm

That pic if from the "Tangerine Terror" belonging to the late Aaron Gross.  That car was a late MkII, but I can say my early ...   08-29-2007 01:18 am

Er...uh....you mean the wheel-well?   ...   08-28-2007 04:51 pm

Rob, Such are the challenges in adapting 40 y/o instruments to work with modern technology.  What you are describing is the same phenomenon with MSD ignitions.  ...   08-22-2007 02:49 pm

Greg think back to a time before Ralph Nader and the 1975 roll over standards.  I have seen a mercury switch somewhere in the engine compartment ...   08-11-2007 01:37 am

I threw away my Unisyn years ago and find balancing the carb by ear is much more effective.  Of course you need to be sure both ...   08-02-2007 02:00 pm

Don't use the flex-hose, they never fit properly, and IMHO look a bit cheap. As Ron suggests, go to your local autoparts store and browse their ...   07-31-2007 12:49 pm

The short answer is: only time will tell. The smart thing to do was put oil in the cylinders to minimize the rings siezing to the ...   07-29-2007 11:29 am

We chatted about developing a kit from scratch quite some time ago: http://www.jensenhealey.com/forums/view_topic.php?id=498&forum_id=2   ...   07-22-2007 12:46 am

Jim, I would balance the 'smallness' of the leak with the 'largeness' of what you are contemplating.  Step one is removing the driveshaft, gear shift lever ...   07-17-2007 07:57 pm

Tim, Sometime post 1974-1/2 (aka JH5) the thermostat housing changed from pointing forward to pointing toward the passanger side of the engine compartment.  As with most ...   07-12-2007 12:36 am

Thanks Ron, Not really interested in having to fab a set of brackets like you had to do on the ITS car.  Maybe the 10si is ...   07-08-2007 01:36 pm

John, I don't think your specific new problem is in the carbs.  When I rebuilt Ron Earp's engine last year we found a similar timing problem.  It ...   07-08-2007 01:32 pm

Dan, From which GM cars is your replacement alternator sourced? Judson ...   07-07-2007 02:38 pm

The stock springs are fine for a road car using C, D, E or 107 cams.  I've been running .388" lift cams for years in both 2.0 ...   07-07-2007 02:36 pm

101.6" = 4" bolt-circle, the .3 is probably a typo JH, Spridget, and I believe the Cosworth Vega all use the same 4x4" b/c. Offset is 3/4" for ...   07-03-2007 04:23 pm

Clif, The Delta-supplied street legal Panasports Ron is running actually weigh a good bit more than the stock (magnesium alloy) JH wheels.  Ron's wheels were on my ...   07-01-2007 01:09 pm

Getting an LBC to fire after 20yrs is a HUGE boost to one's ego and provides unlimited motivation to getting the car back on the ...   06-26-2007 12:59 am

Pardon my dyslexia! Spec 5 thru 9 has the 160 main jet.  On a 2.0 engine I found this jetting way too rich with EGT readings ...   06-20-2007 01:35 pm

Norm, Congrats on finding a set of 48s, I heard they were NLA. I'm not a fan of the Spec 10.  That's how DHLA 45s were/are supplied ...   06-19-2007 03:25 pm

Walter, It sounds like the rings have siezed to the liners which is the typical mode of failure for engines that are allowed to sit for ...   06-11-2007 01:07 am

The new Goetz(sp?) head gasket is about .020" thicker than the original steel-asbestos version.  It adds a bit of insurance when it comes to piston ...   06-10-2007 02:29 am

You'll want to install some form of catch-can between the breather tube and the filters like the Early MkI cars.  As the engine ages and ...   06-04-2007 10:58 am
