G'day again Species
I'm surprised that there are bugger all precision engineering shops in the Isa!!
But at that sort of dough, the Weber starts to look pretty good.
You need to get the throat diameter and jetting right to suit the characteristics of your donk. That can take some doing unless you can pick up a 'crib' from somewhere.
The old Prince Skyline GT (6 cylinder, 3 L) used to have three 45 DCOE Webers on it, choked down to 38 mm, IIRC; BUT it was a bloody long time ago. Went like the clappers! A mate of mine owned one. I have driven it, of course ... :iconwink:
Good luck with it all, mate.
Running that cool sounds as if you thermostat is stuck open as well. The engine will still have been running lean though, and that makes both inlet and exhaust valves run hotter.
Did you have trouble with random pinging? Loss of power? Rough idle? All also characteristics of the engine running too lean.
Today I ordered a brand spankin' new 32/36 weber, don't know how long it will take to arrive but for someone who originally wanted the cheapest option, I'm quite excited about a performance upgrade!
I called an engineering place here in Mt Isa, $120/hour and didn't even sound confident about this kind of work. Later that day I got told to steer clear of them and to look in Townsville but forget that. Anyway, all those issues are true but the running hot. The car appears to be running cold if anything. The suby mechanic actually suggested that I put in a thermostat to make it run warmer. The only time the needle got over 1/4 since buying it was the trip here while towing a trailer and as soon as I hit traffic it dropped very quickly back to it's usual spot.
