1997 GTS - Bogged out at 30 mph, now won't stay running

[ccsentertain]

Hello Everyone, I am a new member and I am hoping you can help me.

Here is some history....

- The machine has run great since I got it two years ago, however, before that it sat in the seller's garage for 3 years prior not used.

- We were ryding the machine doing approx 30 mphs and it just suddenly bogged out and shut down.

- Since the surprise shut down, it turns over fine and starts up for a few seconds, especially when choked. Actually, it will run continious if choked just right. It also won't rev-up at all.

Here is what I have tried...

- Checked the fuel filter and it seems fine.

- Replaced the spark plugs and checked for a spark and they seem fine.

- Inside the carb, I found a little filter in between the fuel inlet and outlet and it had a small block, which I cleaned out.

- Confident I had found the problem, I put everything back together but I still had the same problem.

- I then tried replacing the diaphram, but that didn't help either.

- I then adjusted the mixture screw as per the manual "1(3/4) turn", no improvement.

- I also checked the exhaust, no block either.

It seems like it is so close to running, but I just can't figure it out.

Here are some points that may be of interest:

The person driving it said they flipped it somewhere on the other side of the lake and had to turn it back over, this happend not too long before the problems started.

I pulled the inlet hose off and put it in a fuel can with new gas, but it didn't help.

HELP PLEASE!!!!!

Open the ignition box - where the spark plug wires go and check for water intrusion. Same for the front control box.

Have you gotten RID of the old gray fuel lines?

If not, you have a carb filter full of resin from the inside of those lines.

Your story sounds just like mine.

Thank you JPX, I will check the ignition box as you suggested.

Nate, I do in fact have the grey lines but it does not seem as though there is a lot of resin in the carb from what I could tell. Although, when I tried blowing air through the fuel inlet it seemed very tight and somewhat restricted but I have no point of reference.

I guess my question to you is, would this not gradually start affecting the machine instead of a quick shut down. Also, what should I do besides changing the fuel lines?

The fuel hose problem is a gradual deterioration. But more importantly is gradually causes a lean fuel condition which is bad for the engine.

However, many times the fuel hose problem simply causes the carbs to clog up and generally make the engine run bad enough that you already know it's going badly.

It extreme cases, the lean condition causes the engine to overheat and seize - you'll know when THAT happens.

While changing the fuel hoses (cleaning grey hoses is pointless), you should also check the fuel selector valve for obstructions and clean it out. Blow carb cleaner and compressed air through On and Res ports of the valve forwards and backwards with the knob in different positions. If it is really bad, then replace it - it's cheap.

Make sure to clean off any corrosion on the terminals for the electrical boxes, especially if they got wet inside. There are fuses under the little rectangular boots that should also be checked.
