Hi,
Well, I've got a little over 200 miles on the TR-3A engine now. I have
heard that the head nuts are supposed to be re-torqued after about 200
miles, but can't seem to find that covered anywhere in the book. What are
the pro's and con's on doing this? Is it supposed to be done cold, or warm?
Also, the engine runs very rich. Haven't gone through the whole carb
adjusting routine yet, but I did notice a peculiar thing when I changed
plugs. The plugs from #1 and #3 were very sooty and black (to be expected),
but the #2 and #4 plugs were light tan (just like the book says they should
be). I'm confused. I could understand if #1 and #2 were different from #3
and #4, but why would #1 and #3 be sooty, while #2 and #4 are normal?.
One other thing: I can't seem to get the idle below about 1100. Could this
be due to worn throttle shafts? How do you check for such a condition?
As always, thanks.
Dennis
