Well we finally got around to putting the homemade 1 to 2v adapter on my buddy's '66 with the 5200 that I rebuilt.
Lets just say that the results were less then stellar.
We put it on, cranked it over a couple times to get gas into the carb, pumped it a couple times it fired right up (yay!), worked the throttle a little, which worked like a champ (yay) cracked it all the way open and it died, flat on its face (bummer!). I thought maybe it was the carb to adapter bolts not tight enough, (with the carb floats facing forward the bolt right under the choke assembly is damn near impossible to get on with a socket) so I cranked em all down a little more and tried it again, same results
When you hold the choke open you can work the throttle and the engine will speed up and slow down accordingly but as soon as those choke flaps open, it flops right on its face. We also didnt have anything to spray around the carb/adapter when we had it running, so that didnt help during the trouble shooting process.
Best I can figure is that either my adapter has a HUGE vacuum leak, on the bottom, or through the bolt holes. Or I did something wrong inside the carb when I rebuilt it (it could happen). The bummer part is that he might be moving, with his car, this weekend up to Pullman and he does not want to mess with it on his own, and I am moving to Fargo next monday, so I have very little time (if any) to try this one more time. So I am hoping for some suggestions/recommendations from anybody who has done this upgrade before. I think I need to have the adapter milled down a little bit more on the sides so I can get a wrench under it easier for holding the bolts and if another is ever made tap the holes and put in some short studs.
Do I need a thicker gasket under the adapter?
Is there anything tricky about rebuilding the carb?
Should I toss on my stovebolt adapter with the carb on a little crooked? (ala ducktang)
burnrelief any problems with your install?
