I’ve been away for a work project for a couple of weeks, so no tangible work on Buzz during that time.<\/p>\n
As is often the case, however, I’m always working on something, usually at least related.<\/p>\n
I have borrowed a decent MIG welder and I am learning to use it. I have not yet done anything practical, but I have been practicing skills I will need to make my next manifold, whatever engine it goes on. It’s pretty easy to weld a nice bead so long as you don’t have to stop and restart. It gets ugly then. Welding a piece of pipe to a piece of flat, for example; I can only keep the wire feeding in at the proper angle for about 75 degrees around the pipe until I have to stop and reposition the piece. Then when I restart the weld, she’s not so pretty. I’m sure its just a matter of practice. I’m running out of practice pipe, though!<\/p>\n
Assuming I can muster adequate skill to assemble a thin steel manifold, will I really need to? I have not yet spent the necessary time to see if connecting the vacuum line to the fuel pressure regulator will bring the fuel mixture into line. If so, I will instead need to make an adapter to let me put the twin throttle body on a Weber\/Delorto manifold for the VW instead. That will essentially be a plate with adapter rings that will either fit around the outside of the TB and seal with an o-ring, or more likely, connect with a short length of hose and two clamps, kind of like on Buzz. The second also gives better physical support, so that’s probably how I’ll end up doing it.<\/p>\n
Yesterday and today have been pretty riding days. At lunch yesterday, I got Buzz started with the intent of taking him to and from work, but he was idling funny. I checked and fuel pressure was a tad over 80 PSI. I’ve not seen that kind of pressure except when I had the regulator return line pinched off accidentally, which you may recall burst the pressure relief valve on the old pump. Hopefully, this one has not suffered the same fate. I verified that the return valve is open, but otherwise didn’t have much time for troubleshooting. Perhaps I can take another look tonight.<\/p>\n","protected":false},"excerpt":{"rendered":"
