Corvair Forum

Some of the early reduction starters from Clark's were sent out without the diode harness to mimic the function of the resistor wire "ballast" by-pass switch in the factory starter's solenoid. It's only an issue with the stock ignition coil with ballast as the coil voltage will be low with...

As others said "The Corvair never required leaded fuel for the valves". As a matter of fact even the old water cooled cast iron head engines only needed to run a few thousand miles on leaded fuel for the lead in the fuel to become impregnated in the valves and seats. So ONLY when the valve...

Notched made a good point or as I like to sum it up "Sometimes it's cheaper to buy a Porsche" if you want maximum performance. I appreciate your interest in doing more with the parts you have, but sometimes it's best to leave the stock stuff as is, or at least don't get too carried away. A...

It's been done. This topic could be argued from a lot of different perspectives. In a naturally aspirated engine you ALWAYS have pumping losses. Pumping losses can be reduced using bigger valves, bigger intake passages, more and longer valve duration, BUT you can't have it all. The better you make a...

Good comments so far. I've seen the following problems: Loose flywheel rivets - common after 50,000 miles of use. They can be rebuilt. Loose pressure plate Damaged ring gear on pressure plate (manual) or torque converter (PG). You can try a replacing the starter and hope for the best, BUT a fellow i...

When GM went to the longer stroke engine in 64 they moved the wrist pin location in the piston.

It looks like you have the wrong generation piston.

Welcome - Welll ---- I'm sure your daughter is a great kid, but ALL my neighbors teenage drivers had an accident within the first two years of driving. So make sure you put in a good three point belt system. I'd also upgrade the rear suspension to the 1964 type (or find a 64 car). The 64 design was ...

Brad is correct - before the notched cylinder (1964 - 1969. BTW the 1964 cylinder is a one year only design.) the Corvair manuals showed you loaded the pistons from the bottom of the cylinder. With the notched cylinder it is possible, with great care, to load the piston from the bottom BUT IS NOT RE...

After all these years a number of parts can get swapped so without inspecting the carburetor I can only make guesses. Unlike the primary throttle plate that is notched near the idle circuit orifice the secondary throttle plate has NO notch (or idle circuit 65-67). So YES the throttle plate can be in...

Scott's right about the left - errr - Let's just say the drivers side opens first.

The engine "rebuild" discussion comes up among Corvair and old car folks. Unfortunately for the Corvair an engine rebuild is more expensive than in your typical Valiant, Chevy II, or Falcon. I've seen a number of "pretty" engines that turn out to be junk inside. A "rebuilt&q...

I didn't notice which Petronix coil you were using. If it is the Flamethrower II (can only be used with the Petronix II module) then you have to by-pass the ballast resistor. Many have used the stock or Flamethrower I coil with the Petronix II module. Brad is correct in suspecting the starter ballas...

The front seats should bolt in, BUT keep your old passenger side seat for parts. The passenger seat is usually rarely used and the springs are in much better condition. You can move the seat rails so passenger/driver seats work on either side. Convertible rear seats are unique and hard to find. If y...

CORVO said --- " I installed Roger Parent's linkage kit. Although, like I said, the secondaries are disconnected, the bottom of the heim joint on the carb in question is coming into contact with a shroud bolt, which *possibly* could be keeping the butterfly slightly open." CORVO - I just i...

I think Brad's analysis is correct. I'll add that the secondary carburetor(s) are notorious for sticking throttle plates due to gasoline drying in the throat and gumming up the throttle plate shaft. Three causes: 1) - Opening up the throttle wide open BRIEFLY (especially if the accerator pump cup is...
