Hi all!,
I am having an issue with the engine and need some advice. So it drives fine around town but as soon as i get it onto the dual carriageway and the speed gets above 50 mph ish the engines starts hesitating and i start losing power. I have to drop the speed back down to the 40’s to be able to drive it. It only started happening about a week ago and it’s been good runner for years previously. It’s a stock 1600 with a genuine Solex Pict 34 carb [rebuilt around 8 years ago], stock fuel pump, 009 Dissy and oil bath air filter.
Since then i fitted a new accelerator cable as the old one was about to snap. I am getting full throttle so it’s adjusted correctly.
I replaced the fuel filter and gave it a service/tune:
Adjusted tappet clearances [0.15 mm].
Cleaned and adjusted spark plugs. [Plug gap. 0.70 mm]. All were dry and black/grey.
Checked points gap [0.40 mm],
Retimed engine to 30 degrees at 3500 rpm.
Went for a test run and but it was still happening.
Next I replaced the HT leads and put in new Spark plugs, went up to the dual carriageway again but no difference.
What do you all think could be the issue? Thanks in advance, Pete.
