Are you talking about the fuel filter I wonder?

I saw your post about the plugged line and I am actually having the same problem on the 77 we are resurrecting. The 78 purrs like a kitten after 5 hours of work and 6 years of sitting at some guys house. Both are running, but the 77 only runs on the candy. Judging by the laquer smell I am thinking the fuel filter got gummed or the petcock filter is crapped up. If this ends up being the case I will let you know. I am actually going to replace the in line filter with a GM Hi flow glass in line, so I can check particulate levels since the tank sat for 6 years empty.

Yowza, I am affraid to pull my carbs apart yet, I ran some carb cleaner to dissolve some of the hardcore deposits, but judging by the engine skipping, I would say I have a clog. All I gotta say is I got the pistons free and the carb linkage moving again, and it starts. Not bad for 5 hours work after 6 years of sitting in someones shed and yard.

Seafoam is your friend!
Put on new line and filter from the tank to the pump, and from the pump to the carb rack.
Turn OFF the petcock, remove the line from the inlet side of the pump (the one towards the rear of the bike), take another length of line long enough to reach the ground from the pump while the bike is on it's center stand. Connect that to the inlet side of the pump, and put the other into the can of Seafoam and start the bike. Really doesn't take long 15 or 20 seconds should do it.Your bike will run a little rough and white smoke will come out of the exhaust. This is Normal. Shut it off, reconnect the line from the filter and let it set for maybe an hour. Seafoam does a very good job of cleaning the varnishes out.

You need to be able to clean all the little passages in the carbs. Floats should move freely, needle valve too. There is a small screen under the needle valve seat that probably needs cleaning too. Very small! Don't loose it, it is a necessary item in the carb.

If the bikes have been sitting for any length of time, like six years, you NEED to change the timing belt. They deteriorate from non-use. They also deteriorate from age. Safer to change them. If you did not physically put them on your self and don't know how old they are, Change them! They have a nasty habit of looking good right up until they fail, and take your valves and maybe the pistons with them.

At this moment I have her parked in a garage for storage since I have to find needed parts before I can get any farther. I need a new tank cover, not the sides, I need the bolt that holds the covers on, the ones with the handle. I also need the whole intake can, the old one rotted out badly. Then I ave to find thecarb screens at the bottom of the filter can. I have to find covers for the glove boxes on either side of the cowl, or find a reasonably priced cowl and bag set. The timing belt I can get from Honda as well as the jets. I also need a choke cable. I may need a tank.

So where do I get this seafoam? I am curious about that.

Seafoam is like a miracle fix. You can get it at NAPA, Autozone or Wal-Mart. Anytime I have a carb/fuel problem, it's the first thing I try.

The belts you can get from:

not sure on the pocket covers, but I have seen them somewhere just recent. Maybe google them to see what comes up.

Soak your carbs in white distilled vinegar for 48 hours. You can get it from Wal-Mart - cheap. Vinegar will dissolve rust, varnish and gum in the carbs without ruining the o-rings or felt washers. Soaking in Gumout, Seafoam, etc. will ruin these items. You do not have to separate the carbs from each other when you use vinegar.

I agree with WC on this.
Only having one to worry about is a lot easier on the ol' brainbucket than try to contend with four :roll: . Been there, Done that, changed to a single carb. :lol:
