Triumph Repair: Resurecting TR250, differential level, combustion chambers

Question
Howard, I just ran across this site and was excited to find someone with your background.  I have a 68 TR250 that was running when I parked it in a garage about 8 years ago.  I would like to get it running again and want to take the right steps before turning then engine over.  I did not drain the gas out of the tank so I know that will need to happen and fill with fresh, but is there anything I should do to the engine to prevent any possible damage before starting?  I have not even attempted to start the engine over the last 8 years.  And yes, before you can say it, I am very ashamed of letting something like this just sit around.  Any information you could offer would be really appreciated.

Thanks,
Rick

Answer
Hi Rick,
I would remove the plugs and put a little penatrating oil in the combustion chambers and slowly rotate the engine by hand or just put it in 4th gear and push the car to rotate the crank to be sure it is not locked up. Then remove the valve cover and spray the valve stems also and adjust all the valves.
Besides draining the tank you should remove the carbs and clean them out and check the diaphragms in the top of the carbs. also run some fuel through the fuel lines to flush the line. Check the fuel pump as it's diaphragm may have dried and hardened in 8 years. change oil and filter and check trans oil level and differential level before driving. I would run new brake fluid through the brake and clutch system untill they are completely flushed. Use DOT 4 fluid as DOT 3 will most likely destroy the old seals in both brake and clutch systems. You may have to lightly sand the brake disks on both sides of the disks too. It wouldn't hurt to remove the rear drums and clean them too.
Examine all rubber parts for dry rot, tires, hoses and belts. clean or replace the air filters. I would expect to put a new battery in it.
I hope this helps, let me know how it turns out.
