Do I need a new engine ?

After a 14 year break from VWs and Aircooled engines, I have bought a 1981 devon pop top with a 2ltr Aircooled engine. (Needs a little TLC but I gotta say its super cool.)
We took her on it maiden voyage last weekend, up some hills she managed to get a top speed of 14 mph!
Now I know these motors are not built for racing but surely it should have more get up and go than this.
The engine runs as sweet as a nut no smoke starts first time.

Any advice is welcome.

I had a look, it seems quite clean. The Dizzy cap was in a bad state replaced that still the same.
Runs fine and dandy on a straight

I've got a 2litre '82 and I've just averaged 65 all the way.

Slowest hill was 50.


Try the vacum advance setup. make sure the mechanical side works as well as the vacum.

Similar story to the_blue I have a 2litre CU '81 and travel along happily at motorway speeds. It has to be a biggy to slow me down to 50.

Think I may have found the issue. Looks like there is a circlip missing from the rear retainer on accelerator cable, so the carbs are not opening fully. :oops: luckily I live near some good hills for testing, called the peak district. Hope it works or there may be a few annoyed people tomorrow. :lol:

make sure your brakes are not binding.. I know it seems obvious but hey ho.
