Hi
One of the fuel hoses on my 74 W115 220 broke recently and I replaced it, along with another hose that looked a bit dodge. Shortly afterwards, the fuel pump started leaking petrol so I replaced that too.
All seems to work OK again, except that when the engine is warm and I'm travelling at a steady 40-50 mph, the engine starts hesitating and losing power. Putting my foot down and speeding up solves the problem. It's fine at higher speeds and lower speeds, and no problems at idle. It's dodgy at cold idle, but that's the automatic choke which has always been temperamental.
I don't know whether the problem is related to the fuel pump / hose problems, but I suspect some sort of crud in the fuel line getting to the carb - a Stromberg of some kind. So should I:
1. pull the carb apart looking for a blocked filter (gulp)
2. remove the carb and send it off for a refurb
3. take the whole car to my local classic MB shop, who would probably fix it but are expensive
Grateful for any advice as cash is limited, and I'm no great shakes with a spanner. The car is our main drive so I've got used to relying on it
