Not A Wing, But Still A Boxer Engine

VW used the gasoline heaters too. Boy that was a heat source that would roast occupants!

I fully intend to keep my exhaust system tightly sealed!

Would be great if you could get a stainless steel exhaust system to assure safety.

If it is similar to VWs you just blank off the heater ducts and no air comes into the cabin.. Hot or cold. :yes:

Eliminates clear windshield on foggy days too. Better I think to build it so it works safely.

very nice as always steve ...i hope you do a build thread on this ...that be great

:good:
That's the plan. Gotta have a defroster!

BTW no experience with Corvairs but lots of it with the VW beetle. I had more troubles with keeping the shielding whole to deliver heat than leaky exhausts. Maybe you can find ss headers and fabricate shielding from something that won't rot away?

Here's a link to my build thread on the Corvair forum...

[joedrum]

that last poster on the build thread has it right ...your work is clearly something all can learn from ...i know ive have ..from your work ..now days i really try and capture your way of looking at things when i do my work ...and it led to some great carb mods and so on ...on my bike ...great thread as always ..

and you are really just a yard dog machanic ..that all have trouble measuring up to no matter what there credentials are ..... :good:

 

[Steve83]

Like you, Joe...sometimes the caveman way is the best. I've never had "all the right tools", but when I got this filthy engine, I knew a compressor and blast cabinet would make things so much easier. It also took a while to get used to using SAE tools again, after 30 plus years of metric. I also bought a piston ring groove cleaner, since these would not come clean using the broken ring method. 40 year-old varnish, gum, and carbon are really stubborn!

I'm also thinking of trying a single carb setup. I have most of what I need...we shall see.

Very nice as always Steve! :salute:

 

[Steve83]

Gonna try a single carb setup. I picked up this very sad engine a couple of months ago...it had been sitting, uncovered, outdoors for several years. I was mainly interested in the heads, but it included this carb/manifold setup. I haven't seen one of these since my sand rail back in the 70's...

Before

The carb, a 600 CFM Edelbrock (Carter AFB, made by Weber), was dirty, but in decent shape.

Carb Before

It cleaned up very nicely...

Carb 2

A rebuild kit was only $35. I like the Torx bolts - so much better than slotted or Phillips!

Carb 3

• Steve83
• Sep 9, 2016

I removed the black paint from the runners and plenum. I'm waiting for a carb tuning kit with various jet sizes, and several different metering rods and springs.

Carb 1

• Steve83
• Sep 9, 2016

I still want to do a little more detail work to make everything shine. Also, since the Corvair engine is only 164 cubic inches (2.7L), 600 CFM is way too much carb, so I might disable the secondaries. A fun project...tuning carbs...right, Joe?!?!

 

[slabghost]

I wouldn't be too quick in disabling the secondaries. With a bit of patience (and I know you got that) you can probably find the sweet spot combination of jetting to get it providing just the right charge at any rpm. It took Joe a couple years but it's all documented here how he did it and did or did not work.

 

[dan filipi]

600 CFM too big at lower rpm's but could be fun up higher. What is the redline of this engine anyway?

 

[Steve83]

The single carb is up and running great - on the stand. Under a load, who knows...

Sounds great! No hesitation no black smoke.

+1 :good:

 

[Steve83]

It's tuned 2 stages lean. Smaller primary and secondary jets, thicker metering rods, and the shortest accelerator pump stroke. The carb looks huge on the engine! Now I just need to convince my body to allow me to swap it into the car...
