Starting the engine in the car and a few issues

With June 2025 upon us, it was time to wrap up a few final items and get the engine started. This step is always exciting but also riddled with anxiety!

Good friend Randy Forbes helped us improve the looks of the engine bay by carefully bending a 1/2″ stainless steel pipe to replace the original copper heater pipe.

The stainless pipe clearly looks better in the engine bay!

Then it was time to get our electric fan’s thermostatic controller working. The water temperature fitting in the engine cylinder head is used for the water temperature gauge in the dash. Fortunately, there is also a bung for a temperature sensor or thermostatic switch in the top of the aluminum radiator. We modified an original temperature sender fitting by tapping it with 1/8″ NPT threads to receive a new switch that we picked up from Amazon. It turns on the electric fan at 190 degrees and cuts off at 175 degrees. We also have an override switch built in behind the dashboard. The wiring for the switch was previously anticipated and incorporated in our wiring loom.

With that job completed we then put about four gallons of fuel in the fuel tank and checked to see if we had any leaks. Experiencing none, we then turned on the ignition and ran the SU fuel pump to pump fuel to the HIF44 carb in the engine bay. Again, no leaks!!

With that behind us we then turned off the ignition and cranked the starter to generate fuel pressure as observed at the water temperature/oil pressure gauge.

The engine started right away as anticipated, since we had previously run it on a stand in the garage. However, we also encountered a very bad vibration and knocking sound. The noise seemed to emanate from the driveshaft tunnel. While we initially thought the noise might be coming from the driveshaft striking the body, after thinking about it for a while, we determined that they carburetor was running too rich, and the idle was set too low. once adjusted the engine smoothed out and the vibration disappeared. Hooray! The problem and solution can be seen and heard in Bugeye Restoration Video Episode One Hundred-Seven.

We also discovered that we had a problem with the gear shifter hitting the driveshaft tunnel thereby restricting its full range of motion.

That was nothing that the careful application of the Dremel tool couldn’t solve. After a little paint was applied we reassembled everything and it was another problem solved.

The next problem we encountered was that the alternator was not charging the battery. We are using a Speed Hut, electronic tachometer supplied by Bugeyeguys.com. The electronic tachometerr does have provision for a charging light, but it is an LED. Unfortunately, an LED bulb does not generate sufficient load to signal the alternator to start charging the battery. We found out that you must have an incandescent bulb in the circuit to get the alternator to do its job. So, we modified our wiring and added an incandescent warning bulb in the charging circuit. The wiring modification is routed through Deutcsh connector D1. This process is also shown in the Bugeye Restoration Video Episode One Hundred-Seven. We just tucked the new light under the dash out of sight.

Finally, we made a slight modification in the carburetor float bowl overflow pipe by cutting off the curve at the end of the cunifer pipe and fitting a piece of quarter-inch rubber fuel hose at the end. We also replaced two 3 1/2″ bolts that go through the chassis floor into the gearbox mount with two 3 1/4″ bolts to avoid the possibility that the longer bolts might contact the upper part of the mount and cause vibration.

Dash Fascia and Gauges

When we bought the Bugeye, it came with a working tachometer and a dead speedometer. After thinking about having the original instruments refurbished or buying new ones I decided to buy new Smith’s gauges. Keeping the original tach would have involved installing the guts of an electric tach into the casing of the old gauge since we had previously installed an alternator making the original worthless since it had a mechanical drive off the back of the dynamo.

So the new gauges were ordered from APT Instruments, but it would be terrible to install them in the old dash so replacing old vinyl with new naugahyde was the only thing to do! I began the removal of the dash and proceeded slowly, carefully labeling the wiring to each instrument or switch.

I initially disconnected 2 orange/yellow braided wires to the wiper washer pump. Using a micro switch, my dad had previously converted the manual pump for the windscreen washer to an electric pump. Next was the heater switch. I disconnected a green/brown wire from the harness from a black wire to the heater switch. Then I disconnected a black wire from the heater switch body from a double bullet connector into a light green wire.

The turn signal wiring was next. The switch has three spade connectors. On the side with tow spades, a yellow wire attached to one and a blue wire to the other. A white wire was disconnected from the side of the switch with the single spade.

The Ignition Switch followed. The switch had four screw terminals. The top right terminal had 2 red wires joined together. The top left terminal had 1 heavy gauge yellow wire. The bottom right terminal had two white wires joined together and an red fused wire from the the electric fan switch that had been added. Finally, a large blue wire was disconnected the bottom left terminal. A previous owner had fabricated a clamping system to hold the ignition switch in place, that while primitive, did work. It will be replaced later.

Gauge Lights. Wiring for most gauges is red. The oil/water temperature gauge light fit into the retaining bracket sleeve. The tach light was also red, but this wire was ultimately discarded as it was not needed for the lighting for the new tach.

Wiper Switch. Disconnected the dark blue wire with a soldered tip from the right screw terminal, and the black wire from the left terminal.

Fuel Gauge wiring. One black ground wire was removed from the retaining bracket. A red/white wire for the lamp to the retaining bracket, a green wire to the left terminal and a green/black wire to the right terminal were all disconnected.

Panel Lamp Switch.

The panel lamp switch had three wires. Two red/white wires were joined and connected to the right terminal and 1 red wire was disconnected from the left terminal.

Has three wires: the black ground wire was removed from the top spade terminal, the blue power wire from the switch to the fan itself was removed from the middle spade and the red wire with fuse to the ignition was also disconnected.

The Horn

Had one brown wire from the horn trim ring to the horn itself. The wire was disconnected at the bullet connector.

After removing the starter button and cable, the choke cable and the heater air control assembly cable, and the grab handle, the dash was removed from the car. Two ¼” hex head bolts secured the dash to the body on the left and right side. Two chrome phillips head screws fastened through two brackets from the firewall to the dash and finally one nut is fastened to a stud located centrally at the top of the dash.

Recovered Dash

Then it was time to recover the dash. I purchased some naugahyde at a local fabrics store and some contact cement and went to work. This is the result:

The new tach and speedometer

While not original design, the new tach certainly looks period. The tach required some new electrical connections.  One wire connected to the coil, another to the fused power block and one to ground. These are the installation instructions:Electronic Tachometer Installation Instructions

Demister Hoses

The old paper demister hoses had holes in them and obviously did not work well. With the dash off it was the perfect time to install some new hoses.

Aluminum Racing Pedals

My dad had installed racing pedals in the Big Healey and thought they did give a better pedal feel in addition to looking cool, so I bought a set for the Bugeye as well. They do look nice. I did not use the racing pedal for the accelerator pedal as it was just too close to the brake.
