Engine cuts out
by chrystal » Wed Aug 26, 2020 9:04 am
Twin carb, electric fuel pump on a 2110. Engine runs fine etc until......
Going down a very steep hill and braking at the bottom, the revs die off and the engine stalls. Starts first time. Happens regardless of the amount of fuel in the tank.
Any ideas? Cheers

all i can think of is that when the van is pushing the engine down hill it is still taking in fuel and not burning it all off, and sort of flooding. but then technically it would not start straight away. Bit of a puzzler. is it a steep hill , maybe the van does not like the hill.

Ok, cheers. I do get a bit of popping now and again when I come off the accelerator, the plugs are sooty. It currently idles 1100. Maybe I need to get the carb settings checked?
The engine was done on a tooling road when built by John Mahar in 2018, but due to a serious oil problem has been rebuilt, would that mean the carbs need 're balancing etc?

Has it got a Servo? Sudden vac leak on the servo pipe? Relatively common on Bays. Cuts out when braking.

Sounds like you have several things going on. The 1100 idle could be masking various things. Set the tappets. Get the carb linkage balanced and screws adjusted evenly if its twin carbs. Set idle down to 900'ish and the timing. Then go from there. Might have a gasket sucked in on the inlet which is causing the idle issue if its not simply poor adjustments.chrystal wrote: ↑Thu Aug 27, 2020 10:52 am Ok, cheers.

Thanks For that. No servo, yes twin carbs. Timing and tappets just done. If i leave it, will damage be done to anything? We are in Greece and rolling roads/ experts arnt that plentiful
There was a rolling road 3 miles away from me in Essex!

What carbs do you have?
What pressure is the fuel pump set at?
Are you running a 009?

When you go down hill are you using engine braking?
Does it do it if not in gear?

Engine breaking is fine, cuts out if not in gear or clutch depressed

What happens if you leave it idling sat still on a steep hill for a few minutes?
How long is the steep hill.?
If you coast down out of gear does it still do it?
