The 510 Realm

I run a stock Koyosan Denki 510 fuel pump with my 40mm Mikunis with no return. I with my other car has a elelcctric with a Cheap Purlulator DIAL type dialed in at 3 or 3.5 pounds. If carbs were working before I would have NEVER taken them apart. I seen people put them back together wrong. Yeah, but...

Thanks. I'll talk to my local speed shop guys when they open on Tuesday. Maybe I can borrow a fuel pressure gauge. Any recommendations for a regulator that won't cost me an arm and a leg? And actually, after all that, might it be more cost effective to get an electric pump with regulator (since my m...

I also noticed that there was an inline union fitting plumbed in, IIRC it was between the carbs. There was really no reason to cut the line and install this unless it was a restrictor, so I wonder if that is what it is. Doing some research I see these available. Some of them are just like a union fi...

It's brand new gas. The thing is, the engine hasn't been fired up in 12 years, so all these factors are working together to make it hard to start. I'm going to go through and do the initial settings check, float bowl level check, etc and see what happens. I read in my Weber book (very similar system...

Well in mine, it's tank (actually right now it's just a gas can) > feed line > filter > fuel pump > carbs > return line > tank. Before, there was also this thing between the carbs and the return line. It's the stock type fuel pump (although a different one that we found in the parts area) and testin...

Oh wow. Well that saves me the trouble. Thanks for the links.

I was thinking about the limited resources for these cars that frustrated me when I started working on them. There's obviously a lot more to be found now with people connecting online. I don't know if this has been done, or if people would find it useful, but I would be willing to send out my '73 &q...

Thank you. Maybe I'll buzz over there today and try doing the initial settings on the Mikunis. I think I have a copy of the Mikuni manual and that ancient mimeographed thing around here as well...

No, I haven't checked anything inside the carbs. If you have experience with Mikuni (or any similar) carb setups, does there need to be something inline after the carbs to maintain some kind of fuel backpressure or whatever? Do you have any idea what this thing we found is for? Thanks for the info t...

New here, very glad to find a well populated forum for the 510. I was on the bluebirds list forever ago when I started on this car, and I've finally (like 12 yrs. later) gotten back to putting everything back together. As you can imagine, having sat that long a lot of things deteriorated. We replace...
