Is it a good idea to rebuild your carb after rebuilding your motor


Most certainly it is. It should just go along with the rebuild regardless if it is ready or not.

My pw80 has a ceased motor. I took the head off and there is a lot of surface rust. How do I +go about sorting this outis it possible to get a rebuild kit or is it a write off??


Ebay has piston , ring and gasket kits for about $30. The barrel is cast iron, so if there is no lip a simple hone may do.
I f the barrel is pitted , you will need an oversize piston kit, and a machine shop to bore the barrel to a bigger size.

I have a 69 Ford F100, 1 barrel carburater, the choke needs to be wide open for it to run. When I switch gears, I need to close choke and open it back up when I shift-this is the only way it will run. If I...


You need to rebuild the carburetor. As it is a 1 barrel its relatively easy to rebuild if you can find a kit, but it is the original carb and difficult to find parts. You may also consider buying a Holley 2 barrel carb - it will bolt right on and give you more power, and they are much more common and easier to find rebuild kits and parts. It's possible you may need an adapter plate, depending on the configuration of your intake manifold, but that will be easy to find. You can either shop online or buy from your local auto parts store or high performance shop. That old 1 barrel has had its day and I'm sure it served you well,but I think I would upgrade to a newer carb myself.You may be able to clean it out using carb cleaner spray but it would be hard to clear out that clogged jet that is causing your trouble, and then you will likely tear the gasket when you take the top off that carb.

I have a Zefal HP frame pump. I'm trying to inflate a tire with a Presta valve. It just won't inflate. It doesn't latch onto the valve and seems to big for the valve body. Is there a diagram available...


Let's hope you didn't force it and snap the plastic point off.

Most Zefal pumps come with a reversible head that can adapt to either Presta or Schreader (like on cars). You unscrew the barrel at the working end of the valve, carefully tap out the rubber cylinder and the plastic internal piece behind it.

Insert the plastic piece in either of two ways. Pointy part Out (for Schrader) or just a round opening Out (for Presta). Rotate the rubber piece correspondingly to show the large opening for Schrader or the smaller opening for Presta and place it inside the valve over the plastic piece. Screw the knurled barrel on tightly.

Sounds like the diapraghm fuel pump needs rebuilding. Fairly cheap and simple procedure. Get a fuel pump kit from your local outboard dealer and follow exactly how the old one came apart.

You may also need to get a carby rebuild kit and do that too if it has been a while. Again pretty straight forward. Take photos of carby as you re pulling it apart.

Both these plus a new set of spark plugs and you should be good to go on the water.

The grease in the upper drive area used to be a purple looking grease and the grease in the barrel was a different color and weight. If you ordered the rebuild kit with the O rings and bolts I would use it in the barrel (light film coat on the parts )
