Re: Too high or too low

A quick evaluation is to stand back and project the bottom edge of the body towards the front wheel. It should be just a bit below center. Most likely one side will be much lower.

Re: Cold start Yes - Hot start No! Asdvice sought please.

Make sure the vent on the fuel bowl is open. If it's closed, the bowl will become pressurized and push fuel into the carb.

Re: No, its NOT a Beetle

Sadly, it's more of a commentary on the poor observation capabilities of people. Back in the Eighties I started a new job and after a short period, I drove my black two door to work. Then a few weeks later, I drove my white convertible. A few people asked me if it was the same car that I had painted...

Re: Tracking - too much toe in

Checking the manual for ADO16 the "toe out" is 1/8, so thank you for showing me the light on FWD. We are still left to as where to apply this 3/32 difference.

Re: Tracking - too much toe in

Okay, I was looking for the term stability. That's helps the road feel. Thanks more making me look it up and I had mixed the "nil to" from camber to toe in. Haynes states it as 0 to 1/8 with 3/32 being optimum This shows how tight the Minor geometry. I'm not finding where exactly on the wh...

Re: Tracking - too much toe in

Remember the measurement is to be nil to 3/32. The point of having some toe in is due to any looseness in the linkage that might cause the wheels to wander from straight to toe in to toe out. The looser the geometry is the larger the toe in needs to be to ensure the wheels can not swing out to a toe...

Re: Trying to re engineer the Brake pedal

The concept involves making a new rod to connect to the end of the brake pedal. Instead of point to the rear, have it point forward and slightly uphill. It would emerge above the tie plate in the engine bay. Now the direction of travel needs to change. That can be done with a bell crank. This is sim...

Re: Trying to re engineer the Brake pedal

A pull rod from the pedal can be directed up and forward through the upright for the cross member behind the engine. Then you will need a rotating lever to change the motion to push the master cylinder.

Don't run long without the cover in place. The points axis pin can work its way out. The cover is the only thing holding it in place.

Re: Warming up a Moggie in icy weather.

Possibly, all you need is to increase the idle speed a bit. The first part of the choke only increases the idle speed. If you need to pull the choke farther to get moving, that would be a sign of not being warmed up enough. You report it runs fine and only stalls at idle then it just needs a bit mor...

Re: Gearbox

I enjoy the closer ratios of a smooth case Spridget box with a 948 and 4.55. You may find the same with a 1098 and a 4.22. The gap between 2nd and 3rd is much reduced. The Minor 1st is usually too low anyway.

Re: A strange one.

True, when the piston is up the opening in the gland is bigger to allow more fuel through. However, the SU principle is more involved. Due to the fuel level in the bowl is lower than the top of the jet/gland, the fuel needs to be pulled out of the gland. The steady state of the dashpot (jet - gland ...

Re: A strange one.

Just to clarify, when opening the throttle the intent of the oil in the damper is to slow the rise of the dashpot and needle. The wider opening of the throttle puts more vacuum on the jet to pull more fuel in to initiate acceleration. With out the damper, the piston will rise rapidly and very high w...

Re: speedo reads 40mph when only doing 30mph

First, you need to confirm the odometer. It is geared directly, whereas the speedo needle is induced. If you don't have a way to confirm the odometer, record the indicated speed at various known speeds and confirm that the difference is proportional. These will tell you if the gearing up to the odom...

Re: tyre stem issue TR412/TR413

You'll need to confirm 415 before ordering since it appears in the list twice with different specifications. I suspect the correct number would be in the 42* series. There may be multiple errors in that list.

Re: Braking News

The height difference does make a difference. Both cup seals and the type that reside in grooves in the piston are one way seals. When the fluid cools and when the ambient conditions change the brake system may be below atmospheric pressure. With a low master cylinder that would allow air to enter t...

There's also a significant difference in the layout of the braking system with the Mini master cylinder significantly higher than the wheel cylinders.

Re: Fitting a Brake Servo

It is possible and I recall Detroit sold cars with power assisted front only brakes at one time. However, it's not just a matter of replumbing. The entire system must be designed for the arrangement. It needs to be designed such that the correct amount of fluid will be moved to each wheel and that e...
