Let the Swap-a-Carb Game Begin

Now that I have the truck on the road, I haven’t been too inclined to spend any cold evenings out in the driveway, nor has much happened with TwoTone of late. I really thought I’d be able to get Mikhaila out into the garage over the weekend, but that didn’t happen – too much going on in her social life.

I did, however, don some grungies last night and went out to the driveway to play swap-a-carb with Glinda. I pulled off the current left side carburetor and bolted on the recently re-rebuilt carb of TwoTone. Sadly, the engine would not run right and the entire left bank of the motor stayed cold, so that carb is still non-functioning. After yanking that one off and replacing it with the TwoTone’s other carb, the engine went back to normal – at least normal when defined as “the engine idles smoothly, revs easily, and doesn’t send copious amounts of dark exhaust into the night sky.” I need to put some miles on the car before I determine if the left carb caused the gas guzzling. Before I do that, I’ve got to balance the new carb to the existing left side one. That’ll wait for another evening.

An additional exercise will be to swap the internals and lid from the still non-functioning carb over to the working one on Glinda’s engine’s left side. Not as critical to Glinda’s problem, but I do need to figure out what’s causing TwoTone’s other carb to malfunction – my bet is there’s still a clog in a passage of the carb’s base.

Now onto the paragraph Corvair purists may choose to skip – the paragraph where I regale you, gentle reader(s), with the story of my conquering the truck’s rear end (gee, that sounds dirty). Anyway, last Friday I was lying under the truck on the cold concrete of the driveway and all went amazingly well. The forward bearing was liberally lubricated with gear oil and place into its race. The seal was greased and installed with the gentle persuasion of a hammer via a 4X4. The balance of the pinion assembly was slid home from the back of the pumpkin. The yoke’s spline was greased before being engaged with the pinion’s front end. The washer and old nut were used to apply just enough torque to crush the crush sleeve with only about ten foot-lbs of effort to turn the pinion. The old washer and nut were replaced by the new washer and locknut with liberal amounts of Loctite on the thread to give added insurance against the same problem reappearing. The differential assembly with ring gear and bearings were rolled into place. The spacers filled the gaps on either side. The axles were shoved into engagement and c-rings installed followed by the diff pin and locking screw. The cover was bolted into place with a new gasket. About two and a half quarts of gear oil were squirted in until the level came up to the bottom of the fill hole. The plug was reinserted and it was test-time. I turned on the engine, put the shifter in D, and walked to the rear to listen for any untoward noises. All was quiet, so I bolted on the wheels and dropped her off the jackstands. The next morning’s drive to and from the dump was uneventful – in fact she has no vibrations from the rear at all (surprise, surprise). A big TYL that that project’s behind me.
