I had a small weekend of eating Bacon and some time to look in detail at RAY the HB with a friend Maz.
The morning started well with coffee bacon sandwiches and a quick tour of the shed of plenty to get the tools out, a quick 30 seconds of turning the key on Ray and off would run the engine… OR at least that was the idea…. We cranked the engine it was turning over but it flooded, out came the wet plugs and we dried them off. We tried again and again, each time it appeared to be flooding the car.
At one point we actually ran out of fuel so popped out to get some more petrol and a can of easy start, after we looked at the engine again and reset up the plugs, the timing, the carburettor we started to get some results, the car would fire for one second then die, it appeared we had a electrical issue.
The electrical issue highlighted itself when two of the HT leads melted in half where they touched the coil as they threaded there way around the rocker cover! The Ballast resistor was red hot. The reason it was getting hot was found to be loose connections and possible a duff coil so it was swapped for another coil.
Success! With the new fuel stuck in the tank a little easy start and a replacement coil with terminals cleaned up the car started to run on 2 then 3 and finally 4 cylinders, not bad for 3 hours of annoyances.
For the next few hours we looked at the timing and decided the carburettor was duff, so it was swapped for Weber 32 ICT, in an ideal world it would of been a Solex / Zenith 301Z but I didn’t have the screw in fuel line so had to use another Weber. The one on the car appeared to be massively over jetted. One twist of the throttle butterfly resulted in a big jet of fuel out the bottom, even with the carburettor upside down the same would see a jet of fuel a few feet in the air….
Anyway the result of all these hours of mucking about, is that the carburettor might still not be right (I want to revert back to a Good Known Solex), the timing is out, but so far so good the engine is alive running and it was getting better and better the longer we ran it.
One point of note is that the middle exhaust box was rotten so it was replaced with a straight through pipe, this has reduced back pressure and makes the engine run worse. Today I collected a middle box for a HB. Hopefully with that added back in things will also improve.
By the time we came to call it a day on the engine and fit a nice alarm to the car it was getting dark, so we did a very basic set-up to prove it worked and left it at that. All in all a long day with little to show for the effort, but it has shown me a lot of things that need sorting that I was unaware of earlier, and that’s always helpful.
The evening was followed by curry and beer…. What more can one want ?
