Hi All -

Looking for some advice.

My Suzuki DT-75 got some bad gas.

Here is what I have done:

Clean the tanks, checked the pickups

Clean the on engine fuel filter - found crud and water, but it looks like most of was stopped

Drained the carb bowls through the brass screws that are accessable

I put in new gas, included some gas dry product.

It will run at a fast idle or higher, but not under load. Sometimes it will run, normally, but as soon as I hit some chop, it dies.

Where else could crud/water be?

If I have to, I will pull the carbs off the engine, but to do this I will need a tow to teh ramp, and it looks like a real PITA.

I assume the carbs are Mikunis. Could there be a problem in the fuel pump?

Are there screens in the carbs? Do the brass screws allow junk/water out of the bowls?

I am a good mechanic, and I am sure it is a fuel delivery problem caused by junk or water.

Any hints?

Drain bowls again, sounds like you got some more water in after you did the work. If no dice, yank it and clean those carbs. Run lean on a carb and you will stuff a piston....Quickly.

I think that the main jets are clogged, so I guess I have to tow it to the ramp and bring it to my shop.

If I was running lean, wouldn't it go overtemp? It was more fuel starvation....

Running lean is fuel starvation and very deadly to a 2 stoke.

Bigshot is 100% right about running lean.
Do it to long [ and it dosen't take long ] & you will be buying a new engine.

How can I tell if it was running lean? Wouldn't you get a high temp reading?

Fortunately, I di not run it for more than 5 minutes - I couldn't....

I am going to pull the carbs and make sure that all 3 are totally clean - don't want to run lean.

Thanks guys.
