I''ve since learned that the fuel pump is designed to shut down at 6500 rpm, so that''s one thing I have working correctly, but here''s what I hope is the best news of all.

I do believe I (WE) fixed the damn thing. I don''t know if I posted that I had found a vacuum leak, the one on the rear of the intake manifold that goes to the vacuum advance and 2 other spots. Well, it dawned on me that the import repair shop that charged me 523 bucks to replace my fuel distributor set up the air/fuel ratio with this vacuum leak. Real stupid of them, right? They will hear from me on this. I adjusted it properly today with the vacuum leak repaired and after sitting for a little over 2 hours it started perfect. No stumbling at all. Before my adjustments today if it were to sit for just 10 or 15 minutes it would start hard and stumble badly for several minutes. The proof will be in the pudding in the morning but I''m pretty confident that I got ''er boy!! Thank you kindly for all of your help and I sure hope I can return the favors somehow as I learn more about this little toy. If I do not post with any complaints in the morning then everyone can assume that it''s fixed.It is not only starting like it''s supposed to, it''s running great too.

Going to go out on a limb here early this morning and declare victory over it. I think I had it a little too lean last night. Had to richen it up a little this morning, but as of right now it is starting perfect. Sure wish I had the proper analyzing tools to do it right. Maybe that shop that did the shoddy work will feel the responsibility to look at it again and do it right for me now.

Okay, now it''s really fixed. One, 5th injector line was plugged. Fixed that. Put another WUR on. But the big fix is in the photo I am attaching. It is a meter that reads the air/fuel mixture. Perfect would be 45, but I am running it a little bit lean on purpose trying to squeeze the most mpg as possible out of her. It is not unusual for me to drive 200 miles on any given day. But this meter sure makes setting it properly a cinch.
