Hi guys A few tips if you don't mind as I'm sure some of you must have had the issue! LITTLE BIT OF BACKGROUND: 1147 Herald which I got back on the road 500 miles ago has been running perfectly as I have gradually increased the distances, speeds and time of trips. slightly longer trip last week on the M way so higher speeds than normal and a longer trip, all went well, nice smooth running. ISSUE: Once off the motorway,car started stalling when pulling up so no tick-over every time I pulled up. After a couple of roadside stops and some tinkering with the volume adjuster and tick-over screw, all was back to normal and the trip back was as smooth as the one out. I have taken the car out this week and instantly, the tick-over issue has returned and the car running generally rough. ACTIONS SO FAR Checked compression's, all good Re-adjusted the tick-over and volume adjusters Replaced soiled fuel filter Replaced (very soiled) air filter (which also smelt very fuel rich) Adjusted timing which appeared to be slightly out Removed & cleaned carb mixture jet Checked points gap Checked plugs gaps (rich deposits on plugs) CURRENT SITUATION: Tick-over now good when warmed up and choke pushed full in ISSUE: Car is now very under-powered compared to previously, particularly at the higher speed end, 50mph, doesn't want to go any higher with foot flat to the floor and it was slow getting to that point. OBSERVATIONS: Some back-firing and carb popping when accelerating and slowing Temperature good and stead Oil pressure good Vacuum same as previously was NEXT STEPS: Any thoughts welcome guys and gals but do you think I'm right to be looking at: Carburettor Fuel delivery Re-looking at the timing Like I say, any assistance, thoughts, ideas very much welcome. All the best Gary
