ht engine specs

Got the thread on NT Carb Tuning Basics started.

I hope that all of this isn't a waste of time.

Great idea and wonderful work so far Steve. I'm relatively new to all this information so your posts are extremely helpful to me. The video on 4 stroking was excellent as I would have noticed the difference in sound but would have no idea what was happening or why. Thanks a lot for you efforts.

From what I've read, pulling the carby apart is a very good idea. Some guys have found the main jet and/or needle jet loose in the bottom of the float bowl fresh from the factory.

bloody hotter...colder.... i still get confused :(

if its black but not cause its rich, the plug is too cold, right? and hotter plug has less ceramic so it heats up more, burning off excess oil/carbon..which is the black....

keeping in mind the engines tuned...

yes?

ok...my actual addition here was

PORT TIMING

Ex : 140 degrees. open

In : 106 degrees. open

piston induction : 120 degrees? not very important anyway.

EX port area : approx 260mm2

and a good program for tuned pipes that ive used a few times on other engines...

measurements are as close as i could measure, and are really only a guide... it will only effect the pipes performance by a few hundred rpm either way...
