Dutton Kit Cars and their owners
So, where did I leave off...? Oh yes, carb stripped, cleaned out and back together.
With the carb strapped back on, I again attached a bottle of clean fuel to the inlet of the fuel pump. Lots of cranking later (probably to refill the float chamber) she fired into life, didn't even need any throttle. Excellent. There is, however, a squeak somewhere at the gearbox end of the engine. A lot like a fan belt noise, but from the wrong place. And there's an intermittent grumble from somewhere. Not loud, but it is a bit of a concern. Anyway, she idles at 1500rpm but with an occasional burble, and appears to give full throttle without a problem.
So, I switch her off and have another go at getting fuel through from the tank. I attached a bottle to the fuel pump outlet and crank over. Eventually, I get some fuel delivery. I think less volume than when I tested the pump straight from a bottle, but still looked like plenty. So I reattach the pipes and have a go at starting.
I do get her to start, but it needs a big boot of throttle. And she won't idle at all, anything below 2000rpm and she stalls. But at least the pump is now drawing from the tank, which is promising. However, once up to temperature the engine smokes a lot through the rocker cover breather filter. Which is a bit of a concern. But I get her up to about 90 degrees water temp and shut it off, as I've only put in cheap 5W30 to oil flush it. I drain this and put in 4 litres of Comma 10W40 with a new filter.
So, next steps...
Then, move onto the suspension and brakes!
