I figured out that the atu rod needed cleaned and lured. It was stuck in the open position all the time. Pulled it n cleaned it, put it back in. Now I can't get the bike to do anything. I got a nice POP thru the carb n figured it was 180 out. Swapped it around and got nothing. I did all I can think of but have gotten nothing but a couple backfires thru the exhaust. How can I get it right? I'm at a complete loss and need help...

Check points surfaces; if pitted, file and polish or replace, and remove any traces of oil or grease with solvent. Then set gaps, static time, and finish with strobe. Download the factory manual (free, thanks to Jean Akers' generosity) from www.biker.net or from the links posted by BubbaLeone in the General Board (thanks, Bubba!) for specifics. To check phasing, be sure that the points set that opens at 15* BTDC is connected to the coil for the cylinder in which the piston is rising into the power stroke; that cylinder will have a closed exhaust valve (loose adjuster) after the engine is turned CCW 15* to TDC. |

Is the ATU returning to the fully retarded position?
Weak springs often allow the throw weights to remain at full or partial advance.
Also be sure the lines scribed on the ATU line up (the 180 issue)

I appreciate the help. The weights return to the retarded position now that the rod is cleaned and lubed. Just gotta figure the timing thing out. Got the pins lined up. ill try and reset the points gap tonight and see what happens.

I got it running tonight thanks to yall. I reset the gap and it started right up. It is much smoother, and very quiet now. I mean the exhaust is very quiet now. It was a lot louder. Why did just fixing the atu,and fixing the point gap make it quieter? Wierd

Glad to hear you're up and running, but don't stop there: check timing at idle and at full advance with a strobe, since bob weights often wear to the point that when idle timing is dialed in, high speed timing advances too far. If you find that condition, there are several fixes posted for it; look around and you'll find them.

if the ATU was advanced at idle before the engine would have idled faster, which is the only thing I can think of re: it being less loud now.

I dont know why, but its quieter throughout the rpm range not just idle. I didnt mess with anything outside of the ignition. I had cut the stock pipes off where they met the mufflers, but welded some cheap mufflers on. they didnt make much difference in noise. now its too quiet lol.
