Late August I started working on the Novo and made up my mind that I wasn't stopping until it was running and finished. The first thing I did was
rework the fuel pump. Using a drill of the appropriate size, I restored the check ball seats as they were very rusted. I had new stainless steel balls ready to go in. The original brass balls were in very bad shape and there was only one anyway
(supposed to be two). I got the seats pretty clean and the balls seat fairly well although I would like the lower one (that keeps the gas from running back into the tank) to be a little better. I may eventually end up putting a seperate check in the
gas line inside the tank (out of sight!) if it doesn't seat good enough. Heres a picture of the pump after I got it all back together and working. It's actuated by a lever that runs off the cam shaft. |

Once I got the fuel pump done, I had to tackle cleaning the gas tank and verifying that it would actually hold gas! It had a LOT of rust in it, big hunks, along
with some old gas chunks, and the only openings to the tank (without removing the ~4 inch soft plug in the bottom) are the two 3/8" pipe plugs to drain the tank and the two 1 inch pipe plugs which are meant for filling the tank. I eventually decided on
a tool of my own design, a length of 1/2" copper pipe, bent in an arc at the end and duct taped to the hose of my shop vac! I spent over an hour rooting around in the tank with the pipe, scraping all the rust off the surfaces I could get to, which ended
up being most of them except for the upper reaches of the tank. I eventually got it pretty clean. The two tank drain plugs were rusted in pretty good and the heads just broke off when I tried to take them out. I ended up breaking them out with a
chisel then running a tap into the holes to clean up the threads. |

Here I am rooting around in the tank with the pipe on the end of my shop vac hose. I'd go in this side for a while then lay the engine over on the other side
and go that way for a while... |

There's my handy dandy gas tank cleaner outer pipe-on-the-
end-of-the-
shop-vac-thingy! |
