b2150 running erratically

[brain55]

Ok, it's back to losing RPMs...I think there may still be some air in the system. There are thumb screws to bleed one section but I'd like to do the whole thing to make sure. Should I start from the line going into the filter and work that way or should I start at the block and work back?

Start at the line from the tank to the filter and go toward the injection pump. I have seen the tanks on the B2150's shed their coating inside the tank, that is why it is important to make sure you are getting good flow to the filter and that the tank or fuel line is not plugged. As was mentioned, if your fuel is gelled, that needs to be corrected first. I don't normally think about that, being a California boy where we see temps below freezing only a few days a year.

Yeah, I added some anti-gel/injection cleaner...now that you mention the interior of the tank coming off I have to wonder. When I cleaned the filter last night most of the junk in there had a rust/orange flake consistency, almost like some sort of paint. Should the flow be a constant stream from the tank line or more of a dribble?

A constant stream. The tank lining is more of an off white light gray color. You can take a flashlight and look in the tank to see what is going on. If you are getting just a dribble at the hose going to the filter, the next thing I would do is pull the hose off the bottom of the tank. If it just dribbles out of the tank then it is plugged. If you are getting good flow out of the tank then the line is plugged.

Yeah, it's just a dribble. I pulled the fuel filter again and there was a bunch of junk in it. I went back to the pan I used last night to clean it and looked and there's plenty of black sediment plus flecks of paint. Cleaned the filter again and it was dirty. I also looked in the tank and from what I can see there's stuff there. I think I'm going to have to flush the whole tank and lines. That's an inside job though, so I need to find a place to take it. I really appreciate your guidance on this man. Any guidance for the flushing of the tank? And, what should I do if in fact the inside of the tank is coming off as it appears to be? Get a new tank??

I have sent them out and had them recoated, but that was years ago. Out here in California they have pretty much shut down all of the places that used to do it, along with most radiator repair shops too. You might be able find someone in your area to do it.

Look for an epoxy tank paint. I know they do a lot of old motorcycles this way. You mix it up and keep sloshing the tank around while it dries, but no personal experience. Try a couple good bile shops.
