Just looked through your build thread some nice quality work there, love the carbon dash affair. Nice build you must be pleased

Shhh we were hoping for another 4 reverse gears buggy.


Other option is to flip the diff in the gearbox

No, I flipped the diff

Ran the engine today.

Sounds mean!!!! 

Very cool

Looking good there Jon

Brings back memories of me doing the cam burn on Ben's engine, berfore he got his baffles. My ears are still ringing now 

Rob

I think this motor will be coming out for a proper rebuild, I don't think it's that healthy. very unsure about the single Holley too.

Drove it today.

Annoyingly, 1st gear synchro is a little weak, so looks like winter will be engine refresh and a new set of baulk rings in the box

Jon

It sounds quite good on the video and I like the look of your inlet manifold you have made  . However, with the cooling fan drawing air past the carb, I can see you getting icing problems as it gets colder unless you get a hot air feed of your exhausts. That carb might be a lot kinder on the wallet compaired with the 4 standard carb's 

Rob

The remote oil filter is piped through the inlet manifold beneath the carb, which should help, but I'm not sold on the Holley anyways, so thing it'll be getting a pair of DRLA40's at some point.

The general feeling among the Corvair boys in the states is that it's not a great option, especially as you say, in the colder areas.

The standard setup on the 140 is weird anyways, as it has 4 Rochester carbs, but two are primary, and the other two are secondary, not four identical carbs.

The engine I built for Ben was the 110HP one with twin carb's. I remembered the 140HP one had the four carb's, so they are set up a bit like the Weber progressive carb's then. You use two chokes for normal driving and then the other two carbs when you boot it. If you use twin Dells, are the carb's going to sit very high by the time you get some manifolds made. Could I perhaps suggest 4 Weber 34ICT's, they are nice little carb's and might bolt pretty much straight onto the manifolds and 4 of those could be as cheap as a pair of twin Dells.

Rob

Cheers, will look into them.

34's sound small, but I am aware that with 4 x main carbs (no primary / secondary), there is a danger of flat spots that are near impossible to get rid of.
I'm a fan of CV carbs, the bike carb conversion on a lot of motors is fab, as the Japanese CV's found on the big bikes really do work very nicely giving super tractable delivery.

Jon

could always put some injectors on with a mega squirt or alike.
