Re: Dominator - can't even get it to idle

The old addage...... Most carburettor problems are really ignition problems comes to mind. What's the compression? What's it sound like? That is not gasoline spitting out. Freddie incredibly and crazy rich, spitting unburnt fuel out the exhaust even at just 1100 RPM. :( also, 'cannot even get it to...

So im wondering if a boat trans normally used for say a sbc or bbc can be mounted up to a corvair engine.
Probably not common or cheap, or plug & play, two adapters might need a longer input.
I don't know if I'd want to be out in the water with one engine, that being a Corvair. :D

Re: Fiat twin cam - starting head gasket failure?

Is this what It seems - fire ring failure? More a failure to prep the surface right, looks horrible, and not re-torquing it, maybe no lube or rough bolt head surface caused under torque. I'm not afraid to smooth a lousy machine shop rough cut with wetordry or emery & a block. I've got a piece of ma...

Re: Mark IV BBC cam bearing orientation

Would there be any advantage...
Sure, why not, not that better then adequate vs advantage makes every thing feel more comfortable for you even if it lessens the flow everywhere else.
How well finished are the bearings outlet?
IDK Mark IV BBC, does #3 also feed anything?

Re: Pump gas percolation carburetor

Gas only spurts from the primary shooters. Secondary's has a nice stream. Cracked the fuel line at the carb and gas sprayed. I don't know the carb, but find it strange that it's percing only on the primary side. I think you've got an acc pump problem. Check its check valve for debris. Good luck.

Re: Chatter marks on main bearings

I first thought 'what a clean assembly', no wipe marks on the bearing at all, then wondered why cap has so many holes to F'up the hydrodynamic whatever, with a poorly finished insert's backing/base. Does the varying thickness of the bearings overlay cause the wear pattern, being more compressible? H...

Re: Healey Rod Specification AEC790S

The original bolts are crap too, with a small diagonal pin in their head that usually breaks off.
The bolt's round head has a flat that can be used to hold it when tightening, with a shim or small screwdriver wedged between it & the rod. At least it wasn't Whitworth.
Good luck.
