If you mean no crossover and up pipe, I doubt there will be much air flow through the YH. Better to use 2 known good carbs to start it and run demo for video. Just my

Welcome :wave: Do post photos... that’s always a hit here. These troubleshooting steps were posted by someone else so I’ll quote them. Unplug the sender wire. Gauge should read Full or beyond. Ground the sender wire and the gauge should dread empty. If it passes these tests, the sender is bad or the...

The shim is shown as 4.085 on this diagram. The 4spd has a thick washer on the other side but I don’t know about the PG.

How to make Early Brakes Work by vairmech » Fri Jan 12, 2018

Think that "adapt & overcome" should be added to the subject of this thread. :cool: The ATV/Motorcycle jack and a variation of the Fitch cart keeps engine steady and allows work on the exhaust logs, heads, pushrod tubes, cylinder/piston assemblies etc. My safety protocols call for mult...

I purchased the car a year ago, so this could have been brewing long before I got the car. My bet is that the previous owner was having mucho fun with that 140 while he had it (that's what they are designed for i suppose). It has been slowly getting worse and now you have uncovered the damage. Dave...

...snipped... .... Monday afternoon I get in the car, hit the starter, and the right side of the motor sounds like a coffee can with a bolt in it. I only ran the car about 45 seconds just to quickly determine the general area of the noise. I'm pretty confident it was in the right side valvetrain. S...

When you get a look at your compressor housing this is the Rajay E-flow compressor housing to compare.

7secs of boost .jpg . . The graph is a comparison of a boost vs rpm data capture for two different engines, one a draw through turbo engine and the other a blow through turbo engine. Both of these engines have 140 heads with similar CR, 140 exhaust tubes/logs. The draw through has an F/B turbo and ...

I'm glad your having a great conversation about coils. Interesting. But my alternator is only charging at between 12 and 12.5 volts And the fan light is on. It must have been doing this all the while since the light has been on since I got a higher output alternator rebuilt for the car. It should b...

Hopefully if is something not inside the gearbox. Was this a sudden issue or was it slowly getting hard to shift? Get under the car where the front of the transmission can be reached. Inspect that coupler that connects the shift tube to the transmission input shaft. You might find a broken retainer ...

...snip... Is a OT-20 more for naturally aspirated and a TB-20 more for a turbo? ...snip... Well sir, that's how the Otto cams were designed and intended to be used. OT for non turbo... TB for turbo. These days, there are many workable options for the turbo engine. Currently running an OT-20 with 1...

Those glasspack “baffles” should be called exhaust restrictors. Looking at those small holes makes me wonder how much reduction in flow and increase in back pressure they cause. Looks like at least 50% reduction, Is that the intent or is it to reduce loudness? https://www.corvairforum.com/forum/down...

...snipped... I have driven it around town a few times, but I have been very gentle on the gas and haven't got it above about 40. ...snipped... Soon, I hope to get on the highway and see how and if my transmission shifts to 2nd. I would think that if you have been gentle on the gas and gone 40mph, ...
