" For some reason, I was thinking the AIR engines had domed pistons since the cylinder heads were open chamber." I believe 68 and 69 AIR used same open chamber head, flat pistons for 95 HP and domed pistons for 110 HP. Jim Brandberg Isanti, MN CorvairRepair.com

I'm okay with your math .090 divided by 2 minus .010. I hope it works out in real life when spending for 12 pushrods, there is an adjustable one for measuring but probably not cost efficient for one time use. Jim Brandberg Isanti, MN CorvairRepair.com

Yes that's severely wrong. You're in a bit of a pickle there as you have to be extremely careful to press the pins out without damaging the piston. When I'm doing it I usually don't care as the pistons are being replaced. It's too bad that you can't just leave them for another project but Late pistons on Early rods is not a good combination. The piston usually resides below the to

<<>> When concerned in the past I've used a pair of solid lifters as a test before assembling which doesn't help your situation. There was a thread recently about filling lifters before using. I haven't been doing that but may start the practice. Yesterday I was doing the opposite, bleeding lifters down with a 5/16 bolt in the vise. They were new old lifters where 8 out

I use roller rocker hold down nuts as head nuts on my race engine. My problem with milled heads and stock nuts was going down past the threads. A bonus with these nuts is an allen set screw to lock it in place. Also maximum thread engagement. I just buy stock plated head nuts from Clarks and haven't had any trouble. I do only chase the threads with an oiled Grade 8 nut and don't use a die un

The pushrods should be fine as far as strength is concerned. Sometimes a different length is called for so the rocker arm comes into good contact with the valve tip during it's sweep, valvetrain geometry. Some things that affect pushrod length are a regrind cam with smaller base circle, milled heads and different thickness gaskets. You can get it assembled and observe the rocker arm to valve tip

Good information, thanks. I had a new one a year or so ago that would not draw fuel so I just returned it. It makes sense that there can be other problems with valves besides coming out. Jim Brandberg Isanti, MN CorvairRepair.com

Are you still running 650 Holley? It might be sort of big but you do report it's running well. Is it mechanical or vacuum secondary operation? Do you run it on the street or offroad? Corvair differential and transmission or VW? Regular or reverse rotation? Sounds like a lot of fun. Jim Brandberg Isanti, MN CorvairRepair.com

Sometimes you can tell bad rubber hoses when bleeding the brakes, with the bleeder open the pedal is still hard to push and you get very little volume into the bottle. I try a low speed skid test on a dirt road or asphalt with a little sand to see if all 4 wheels are locking up. Low speed to see marks from all 4 before they merge into just 2. I'd make sure all 4 hydraulics are doing som

I started to reply yesterday but thought someone would have better information. It seems to me that sometime during the 66 year production they began installing an extra provision along the outer roof for a shoulder belt, even though the belt wasn't provided yet. It was just a threaded hole with I suppose a welded nut. If you're looking for a side to side bar for competition belts I don

I hope it's not a dumb question but when checking vacuum are you turning it over with the starter or just pushing down on the bench, like when doing the wocka-wocka test? Jim Brandberg Isanti, MN CorvairRepair.com

I would guess that all 140 heads have similar combustion chamber volumes but I never really checked. CORSA Tech Guide has the volumes listed in a chart. Folks have been just swapping in whatever 140 head they have to repair a dropped valve seat for years, whether it's a good idea or not is debatable. Jim Brandberg Isanti, MN CorvairRepair.com

To repeat what others have said, I would check the positive junction at the frame rail and I would check the red wire at the big junction block. Sometimes I will just splice in a by-pass or it might be a good idea to install some sort of a super-fuse at the same time. Someone also said to check the grounds, also a good idea. I don't think I'd replace the whole body harness just to correc

I'll try cutting the top of the spring instead of the bottom. How do you test the vacuum? I've never considered that. It's good to know that Carter is still making pumps too. Is it easy to tell that it's a Carter and not an Airtex? Jim Brandberg Isanti, MN CorvairRepair.com

My interest and contribution to this thread was to hopefully find an in-stock spring somewhere to reduce pressure. It seems that we've run out of steam searching for that. Cutting and reforming springs seems crude to me but I guess that's what we've got. I found tapered springs a lot harder to search for than regular springs on spring company websites. Does someone have pictures of before

Egil's wife Judith was somewhat overwhelmed by the process of getting rid of all that stuff in 1998. A lot of it went at fire sale prices and a lot of it went in the dumpster. She was a good gal and I'm sure she didn't mean to give you the screw job. There was probably just too much going on in too little time. She didn't know or care about old cars. I don't think the resources covered the debt.

In my searching for the other Amblewagon I started by looking for other folks involved at the Anoka County Airport hangar around 1998, including the fellow with the variable valve timing Corvair 3 cylinder. I found this short article interesting, an engineering type guy, patent law not so much. There's an even shorter version on Wikipedia. From the get-go in 1959, Corvairs have been

FedEx has a cooperative arrangement with USPS as well. There must be something that makes it worthwhile for both parties. I'm guessing FedEx and UPS are using USPS for delivery in small volume areas where USPS is going anyway. In return I would imagine FedEx and UPS are handling some of the shipping volume to fill trailers since they're going there anyway. Perhaps with double trailers, one has Fe

It sounds like it's the online thing where the Corvair vendors are falling short. I can't argue with that as I hardly do any buying online except for Ebay and I've cut way back on that. I'm used to the Clarks paper catalog and phoning in the order to an answering machine, sort of an old dog and new tricks thing. I do use the online catalog when I have a part with a number and I don't kn

I don't know who you're dealing with but I've always had good luck buying new and used Corvair parts. There must have been a few not quite up to snuff but I honestly can't remember anything bad enough to stand out. Jim Brandberg Isanti, MN CorvairRepair.com

You got a bit of a hard time the first time around so I'd like to thank you for posting the link for the second installment, I enjoy reading them. I beat a Factory Five Cobra in the rain at Road America in a SCCA Regional race with my EP Corvair. The Results don't mention the weather so I think it still counts. I don't know what class he was in, probably the ITE catch all. Jim Brandberg

It was Fran Schmit holding the camera and talking, along with Brian Carlson hands on the vehicles. There's a third fellow Roy who I don't know. Paul Sergeant was fairly well connected with that scenario in 1998. He also seems to have a fairly good memory which helps a lot. I will certainly report anything I find. I'm more interested in something being done with the other Amblewagon than ac
