I checked the carb, but no wires going or coming. The switch I was told about is on the accelerator pedal and all seems to be ok with that.

I replaced all the vacuum hoses the first day I had it. Figured they all could use a new one.

Hmmm, I'll have to check it. Any idea what one costs and where I get it?

I'll check the modulator....how will I know it's bad if (it's not loose)? I like the 400's and awful lot. I will eventually get someone to rebuild this one and put a shift kit in it. I just wish I could get it to hang in 1st a little longer right now. I can live without the 3-2 downshift, I can always do it manually.
Thanks for the info....
