Very nice. Thanks for the information. ...   12-07-2024 02:20 am

Interesting idea. The oil pressure on my JH takes about 15 seconds or so to drop below 10 psi when I shut off the engine. ...   12-06-2024 09:44 pm

Uni-Syns don't work all that well, anyhow. They put too much load on the carb being measured so you have to be quick. These guys ...   05-26-2024 07:22 pm

I'm a bit late to this thread, but I also tried Grosse jets and had problems. They sounded like a superior design, but did not ...   05-17-2024 04:18 am

Not sure if the mounting assembly needs to be replaced. What sort of condition is it in? It looks like it may have some rubber ...   09-11-2023 02:08 am

Did you also remove the mounting to crossmember bolts (#4 on the pic)? if so, then it is likely, that the crossmember is just being ...   09-10-2023 06:27 pm

I am very surprised that a 912 engine idles well at 550 RPM, but do not see any particular problem with it. Have you ...   08-15-2022 12:30 am

I also got a Gustafsen starter from Dave Bean. Been happy with it so far. It IS possible to install it rotated enough ...   01-03-2022 10:07 pm

Not sure if this helps, but many years ago I found some replacement aftermarket wheel bolts that worked. (See comparison pic). I measure ...   11-29-2021 01:08 am

Not a chance unless you can come up with some way to jack up the engine. I jacked up my car and took a ...   11-08-2021 09:26 pm

There is an adjustment screw in the stock tachometer accessible via a hole in the back of the case. These guys tend to age and ...   06-21-2021 09:54 pm

Idling is where everything tends to be most finicky: timing air-fuel ratio, etc. According to my manual, idle or static timing for Strombergs is ...   05-10-2021 02:31 am

Additional thoughts: Not enough current activating the solenoid could also be a problem. Low current might keep the solenoid contacts from making good strong ...   04-25-2021 07:18 pm

Those batteries should have plenty of cranking power unless they are bad. Unlikely for a new battery. If you can get another car ...   04-25-2021 04:23 am

Coolant can also get into the interior if one or both of the hoses going to the heater are cracked or loose where they connect ...   03-22-2021 11:26 pm

Both Tim and "Distributorguy" have good points, except for the "load of crap" part. IF everything in the HV circuit is good and the timing ...   03-13-2021 02:32 am

If the thermostat controlling the coolant flow is working correctly then having the fan operating continuously should not make any significant difference in how fast ...   03-07-2021 02:11 am

Make sure the nut at the back of the shifter mechanism holding it to the insulator is tight (assuming your trans is a Getrag 5-speed, ...   12-01-2020 11:40 pm

The official build date was 12/31/1974 though I doubt it was actually built then. Back when I bought it 35+ years ago, all the ...   08-31-2020 05:39 am

I would definitely replace the TR6 needle. I doubt either of the needles are the main problem, but the JH engine was a major ...   08-14-2020 12:19 am

What to buy at this point depends on how much of a hurry you are in and what kind of shape the carbs are in. ...   08-13-2020 05:20 am

If the car was running OK and you did not smell any gasoline when running, my guess is that the leak is small, possibly leaky ...   08-12-2020 08:19 pm

The quickest way to solve the fuel pressure question is to install a pressure regulator close to the carbs that has a readout dial. ...   08-12-2020 08:10 pm

When you switch the needle and damper assembly do you also switch the spring? I think the springs for a TR6 are significantly softer ...   08-12-2020 08:02 pm

The first thing I would check is the fuel pressure at the carbs. This should be less than 3.5 PSI. More than this ...   08-12-2020 06:48 am

Never mind. What I was thinking will not work. If the system will not trigger the tach as is, I think you will ...   07-26-2020 07:46 pm

Once the wheels are off, you should be able to just pull the drum off. There is a hole in each drum that allows ...   07-20-2020 04:32 am

My starter was doing more and more clicking before starting, so I decided to get the Gustafson. On the plus side, it is smaller, ...   07-17-2020 10:30 pm

The coolant leak could also be from the hose that goes to the intake manifold. Since you have the manifold off, it would be ...   07-17-2020 05:53 am

If the bottom o-ring is leaking, then other rubber parts may be going bad as well. I recommend taking off the top on one ...   05-15-2020 05:26 pm

Sounds to me that the changes you made should help, at least a little. According to the manual, 0.023" gap is where you should ...   05-03-2020 04:25 am
