for the turbo carb to start the choke must be set to close fully this is an easy adjustment , remove the air cleaner housing losen the screws on the choke housing and rotate it to close the choke , it just needs to close fully not tight , once closed you should then check the choke while holding the throttle wide open it should open the choke about 7/16 of an inch and releasing the throttle the c

Darrin the blow off and the waste gate do not do the same thing the blow off only dumps air when the throttle is suddenly closed as in up shifting the wastegate opens when the exhaust pressure exceeds the spring pressure holding it shut and since we are talking about a modified turbo system you should also have an exhaust pressure gauge if you really want to make power , the boost and exhaust pre

I would use a block of wood and a good hammer place the block on the horizontal sides of the pistons give each piston a good rapp on both sides of the piston and all 6 pistons . do not put much torqk on the balancer bolt . from your discription it should come loose

if you would heat the gear and remove it you may be able to verify weather the gear was not installed all the way and that caused the washer to fail , if that is what happened the very end of the bore will be smaller than the other side . I have seen this before on a rebuilt engine , altho the washer hadnt failed the motor dropped a seat and it fractured destroying all 3 cylinders and pistons , o

I would get it on a hoist and inspect the main frame ( I know it's unibody ) but the FC's have frame rails they just arent removeable . as others have said it will be fun to drive as is , if the shift rod goes under the tank ( 61 62 and some 63 the bracket at the bottom of front cross member is usually worn easy to remove I over bore it and install a bronze bushing and also the factory

I recently had a car in that the owner should have sued the shop that did her brakes, the only thing they did right was install new brakes hardware and drums, the shoes were not adjusted up, new rubber hose lines for the back wheels but did not install any of the hose retainer clips non of the steel lines were tight enough , all of them leaked . I replaced the front hoses and the lines above the

Junkman although it does have blow by it is not bad enough to warent a rebuild it is not pushing oil , the main ign failure was caused by the ign switch, plug gaps a little wide and probbobly running hot with the 3plate and more importantly the missing shield , with that not there it is a huge air pressure loss, even bigger than the 3 in hose on the right front of the shroud

no reason to dought those numbers the head temps prove it even on a 97 degree day on a high speed road course 15 psi boost. never saw more than 425 head temp and it drops as soon as I slowed down.

I have to ask why do you want to go rich on the Jetting , I have wide band o2 sensor and stock 180 that I tested had cruise afr of 13.5 and 11.5 boost . I went for a ride in a 64 spyder he has wide band in and his cruise afr was barely 13.1 and boost was dead rich at 10.3 . I use a qjet on my car and it runs very good with cruise at high 14. and even 15.ar numbers under boost anything at low 12.0

I have done what you are contemplating however true turbo heads have a lot more mass to secure the tube, what I did was have a welding shop build up the area on the outside witch will work provided you drill the hole at the correct angel , my mistake was in drilling to the size needed , it should be drilled undersize and reamed to the proper size , I had to use steel puddy to seal it up. as far a

I luv all the custom engineering , and laying it all on the line to go 176 mph. I dont have asperations to do Bonivill but I am working towards breaking 100 in a quarter mile with a very street drivable turbo corvair.

the 180 housing is larger internally, the turban is bigger and the housing doesnt sgeeze the exhaust gas as tight to spin the turban , thats what the ar nummbers mean , I think the 150 ar is .5 and the 180 is .7 when you have your turbo built hybrid the compresser or cold side is 180 and the hot side is 150 and boost comes on in all 4 gears . so all those 150 turbo's are actually the part y

I have an old vaccume, preassure fuel pump test gauge I use on every car that I own and every one I work on electric or mechanicle , I have tested new pumps from clarks and they are very close to correct pressure ,all new pumps should be dissasembled and all surfaces should be flat sanded for better seal surface mating , they are poor at best , also check the crimp of the diaphram and the pushrod

the early model spyder exhaust at that joint is a problem, and I agree with Jim the late model design is much better and fits the early engine , because you have clamped it tight it could be very hard to remove , hear is what I will do for the next spyder I work on and if I have to I will cut the cross over pipe below the slip fit , once removed and in the vice I will be able to remove the crimp

absolutely no rubber fuel line in the engine compartment because if you break a fan belt and it snags the rubber fuel line you will have a fire you can't put out. and why did you replace with rubber from tank to engine? I have never read of anyone reccomending that. have you removed the fuel sending unit from the tank? it sounds to me that you have a restriction inside the tank, I have seen

using a dyno for testing and tuning is exactly what they are for But that is time consuming changing anything but timing, it helps to do the pulls in 3rd gear that saves time and if it is a newer dyno the computer compensates for 3rd powertrain losses , I have been on the dyno many times and since they dont list a corvair in the program for those losses I came up with a way for it to be accuret

just looked at your picture and the air cleaner is mounted improperly , it should fit direct to the carb not with the extra tube and clamp , show a picture of the fuel line, fuel filter and the air cleaner support .

the large circle is not a vac port nothing atatches there , if you loosen the 3 screws on the black choke thermal and rotate to open the choke it should idle down you will need the air cleaner cover off and look inside as you turn the choke cover to see when the choke opens , the problem with doing this is it will be very hard to start if not impossible . the 2 steel lines are very easy to insta
