Hi all,
Well, I assume it is the strombergs. I've just bought a 1974 144 (genuine one owner) and yesterday drove it home. About 850km (525miles) in pretty hot weather most of the way, pulling a small trailer with a spare motor etc plus a trunkfull of other spares. Over 30C pretty much all the time.
It starts cold very easily and idles smoothly. When hot, e.g. after refuelling, it nearly flattens the battery trying to get it to start. Turns over a lot of times, a very hesitant catch if I'm lucky, then it very lumpily idles until it finally catches properly. Then it runs fine.
PO said he had the carbs rebuilt about 4 years ago. It's certainly running rich - you can smell that and the plugs were pretty carboned up when I pulled them at home. Replacing them with new NGK BP6HS made no difference to the hot start. I haven't yet checked timing or points gap, but it is running well. They are next on the list.
Idle is also pretty eratic. Idles as high as 2000rpm or so low that it stalls. Generally idles high when very hot.
Any quick fixes here? Or just hunt in the parts cupboards for some SU HIFs that I think are there somewhere and forget the strombergs.
All help is most welcome.
Regards
JohnH
