1962 Triumph TR4 Engine Rebuild Series, First Start Up, Cam Break In and Weber DCOE Shenanigans....

The 1962 Triumph TR4 is back up and running after a full engine rebuild. Cam Break In accomplished along with some test drives after playing around tuning and setting up the Weber DCOE 42 Carburettors.

I’m a stock guy 100% no cam Webers always a problem. But you guys are totally capable of fussing with that . But I’ll keyy try p the SU and stock cam and enjoy it the way it was meant to be. But I do appreciate you guys steadfast, getting it done with the Weber

Carburettor “air horn” = “trumpet”….. 😊

She sounded great! I am very glad to see you getting all that progress done in your cleaned up garage, it sure has more space now! Watching the closing of the bonnet with the Webers, it looked like a spacer between carbs and manifold could help, as it would put the linkage in the raised area.

Why would you put dual weber carbs on the engine, but not put an exhaust header on it? All the extra breathing capacity arising from the weber carbs is probably being lost by using the stock cast iron exhaust header and stock exhaust. Weber carbs are made for racing engines, not street engines, in my experience, and run poorly on the street because the Venturi sizes need to be decreased from the sizes recommended by weber which is for racing applications and lots of wide open throttle use. With that said, best of luck to you in getting this combo to work.

My 77 124 spider had dual Weber 44S they definitely have a distinctive sound, especially with a twin cam engine the triumph sounds great I’m definitely a sucker for the TR four.😊

hi, i have DCOE's on my TR4, they came with the car... the mechanical pump seems to deliver enough flow and pressure, i have an original AC pump. I added an inline fuel filter to decrease a bit the pressure. Also the front plate hold by 2 screws between the barrels that are hiding the return spring need to have a hole in the middle, one of the 2 carbs did not and a i had a fuel leak when i stopped the engine. The hole avoid fuel pressure building behind, it is not well documented.

Time for BEV swaps. No more vacuum leaks or fuel pump problems or timing or exhaust leaks or ...

[@mikeg5877]

haha, I see your fuel pump is pointing in the correct direction 🤣

[@johnclancy9860]

David, you characterized the oil pressure issue as tolerance issues but what actually solved the problem directly , thx

[@BruceBoschek]

Satisfied to be second. Nice to see an engine running quite well on Webers. Sounds good! Looks....

[@Michaeld-jk4kv]

Nice. That car is sounding really sweet.

[@craigwiest772]

Great to have you back. Engine sounds great. Good to see progress on this car.

To run Webers properrly, you need to convert your distributor to mechanical advance only, eliminating the vacuum advance. It involves changing the weights and springs in the distributor. I've never done that with a Lucas dizzie (I'm running a Mallory) so don't know the specifics. Maybe someone else here does or there is info online... or reach out to some of the folks with experience running Webers on rheir Triumph 4 cylinders cars.

I admire your hard work and patience, Tush. I really like the look of this car. Hope to drive it someday, lol!
