[TR] TR6 Mechanical Engine Problem

[Andrew Uprichard]

I just had a “dump” of several older posts arrive this morning.  Maybe everyone else got them a while ago and the problem is at my end.

 

Anyway, to answer this specific question, remove the oil filler cap so you can look inside the valve cover.  Crank the engine- if the chain is broken there will be no rocker movement.

My 1973 quit going at 65MPH without any indication.  I noticed some black smoke from the exhaust when it happened.  I was running the car fairly strongly for two hours or so after adjusting the HS6 carbs and getting the car back on the road after a few years.

 

The car will not start and doesn't want to start.  Fuel and spark appear to be OK.  I tried starting fluid to no avail, plus I have spark at a plug.  

 

I intend to clean the plugs if they are fouled, check static timing, by-pass ignition switch power to the coil, and confirm the engine will turnover by hand.  

 

For some reason, I suspect the timing chain.  How can I check a problem with the timing chain?  What else can I try?

 

Thank-you,
