Hi All

I have recently bought a 66 2000 which has a running issue.

It's starts first time, ticks over nice and warms up has it should, however there is no power to the extent that you have to changed down to 2nd to get up a minor incline. She will also not go above 50mph ( takes forever to get there).

My local garage has done a compression test and reported that all is good in that department. There is a an issue with low voltage going to two cylinders so I'm going to change the leads but I'm not convinced that this will give me more power. Ok, these old p6 2000's won't win any races but this car is slower than a horse and cart.

Any suggestions ?

By the way, the car has reg GRU774D in case anybody knows it.
 
It could be a problem with the carbs, but my vote goes towards ignition timing being off. You can also check valve timing by checking out the cam timing sticky in the 4 cylinder section. Good luck!

Also you might get more answers if you post in the four cylinder section too.
 
That's normally symptomatic of valve seat or valve recession. You need to check the valve clearances first.
If the car has emission control (later 66-67 2000) this restricts the power a bit compared to the earlier cars but I would expect 0-60 in around 14secs and it should easily get to 85-90mph. The non emission control cars can be little rockets when set up well... I am always surprised at the difference between a good early car and a good later 2000.
Unleaded has a slightly different burn rate to leaded. I would use super unleaded, with the timing set up for 97ron as the engine was designed for this and the mixture needs to be slightly rich. Don't forget a lead additive like the castrol valvemaster...
But I am guess the valve clearances are where you need to check first

Thanks for the advice guys

I did think it was the timing myself but the local garage said they couldn't find the timing marks on the pulley ???

I'm going to do the job myself once the workshop manual arrives

That's could be because they're not there. Early engines didn't have them and need to be timed through the access plate on the bellhousing.
