Here's a pic that shows where my pan was hitting the crossmember.

Here's a pic of the bay of the white REPU. I've got a few more, but I don't want to clutter up this thread.

Jeff20B: What carb is that you have on there?Is that a 12a I see?

75 Repu

Fell free to start a thread about your project Jeff.. It would be nice to get some more Repu traffic in here.. Plus the first gen guys have much in common with us.... I'd also like to know what kind of Carb that is..

Jeff20B

Dellorto, 4 port 13B.

Nice.. are those Dellortos and Weber Carbs easy to tune..?

Jeff20B

I couldn't tell you. I've never tried to tune it, but I have played with different fuel pressures. When it was stock ported, it seemed to run best with 4.0 PSI (according to the cheapo regulator, but Racing Beat suggests 4.5 PSI). Now that it's been ported and almost done breaking in, it may run a little different. The first oil change is coming up. I'll check the plugs at that time.



Out of two Dellorto carbs on two different engines, this one has always had a bad idle. It has improved since I rebuilt the engine and now runs like it did on an '86 6 port in my friend's '79 SA. Perhaps the idle circuit is gummed up?

maybe, maybe you need to sync it?

I thought that carb looked familiar.

Jeff20B

I don't doubt it. But then again, the idle has a bit of a brap to it. Like SPRT says, it's like brrrp brrrp brrrp brrrp. Then as soon as you get on it, it's smooth.
