[6pack] TR6 - Help Wanted

[Sally or Dick Taylor]

DCTR6---Where to begin? Air, fuel, spark or compression? One or more of these, to be sure. As always, I'd check the easy ones fiirst.
 Open the dist. cap to see if the point gap has closed up. (This can happen more easily when changing to new points, as the nylon rubbing block wears off a high spot) A closing gap will retard the timing.
A check with a timing light can confirm the loss of advance.

A partially clogged fuel filter (or any other drop in fuel volume) can cause the same loss of power at elevated rpm. 

Do a run without the air filters, if these are suspect.

Lastly, if nothing shows up, do a compression test. If one or more cylinders is down in pressure, then do a leak-down test to get more info as to engine area.

Let us know what you find!

Dick

  I've just returned from a 2,630 mile Southern trip to The Mitty at Road Atlanta, some touring around Charlotte and a trip to the NC shore, all in my TR6.  All went extremely well until about 100 miles from home.  The car starts and idles fine, and runs in the low revs OK but will not run over 4000 RPM. It just seems to choke - it made the long hills on I-81 in Pennsylvania a real chore - I'd get going 75-80 mph at the bottom of the hill and would barely be doing 55-60 at the top - it just wouldn't go any faster. I checked for the obvious (vacuum hoses disconnected, etc) but found nothing. My only theory so far is a possible carb problem (possibly a torn diaphragm in one carb?) but I can't get the car into the shop to check it out  until next week.  Any other ideas where to look?  Thanks.
