I just purchased a used (44miles) Ambassador a couple of weeks ago. I know the Ambassador has it's problems, but that's OK because I like to fool around on stuff like this anyway. Hey, what can I say other then I'm retired? One unexpected problem was the front tire blowing out last week! After inspecting it, I found one side of the rim lip was not rolled in all the way so there was a exsposed sharp edge that cut the bead of the almost band new tire which alowed the tube to ballon out. I thought someone was shooting at me! This could have ended badly! What's really sad is the CVT unit. The whole idea of a CVT is, for the most part, defeated with the slip clutch on the jackshaft. Give it gas and it's slow to accelarate while making a lot of noice. It reminds me of the old Buick Dynaflows. Has anyone considered removing the automatic clutch, locking the driven variable pulley on the jackshaft and installing a longer belt so it works like a Comet clutch? OR maybe better yet, just replacing the whole unit with a 20 seriers Comet unit for under $200.00? Because I'm not a big fan of automatics, I was thinking of installing double pulleys on the crankshaft and double pullies on the jacksahaft. One set would have maybe 1:1 1/2 ratio and the other set would have a 1:4 ratio or so. Each belt would have it's own idler that would be controlled by a left foot rocker type pedal. Pushing down would tighten the 1:4 belt (Low), In the middle both belts would be loose (N), and up would lock in the 1:1 1/2 ratio (Hi). Your thoughts please?
