Help with leaking gas Issue

ONNFIRE
I have a 1989/90 YS624 as pictured in the second photo on this Web Site, the one with more of a square gas tank cover. My question is, I started to smell gas in my garage and noticed my blower had gas leaking from the top area of the gas tank cover and I only had a small amount of gas in the tank which was well below the area of the leak. Has anyone experienced this before or have any ideas what might cause this. We did have -35C degree temperatures the last time I used it. Any ideas would be appreciated.

You should check the glass fuel petcock under the tank, as they leak when the get old, if you have a machine with tracks this will drip fuel onto the track and damage it over time.

Thanks for info: The fuel petcock is good; The leak I have is coming from the upper to top of the tank where the seam of the plastic gas tank cover is and leaking onto the exhaust. I just find it odd that the leak is higher than the level of the gas and the leaking occured when the blower was shut off.

If you have one of the Plastic fuel tanks this is quite common, they usually leak at the seam due to prolonged vibration. These plastic fuel tanks are no longer avialable due to this, they are replaced with a steel tank when replacement is required.
I would be very concerned about fuel leaking onto the exhaust.

You could always try wrapping the gas tank with duck tape. Maybe that heavy duty gorilla duck tape.
You could see if that takes care of the issue short term.

Well I found out the gas tank has definately let go, so I am now in need of one of those plastic tanks. I believe they where sold on a 88-90 YS624. If anyone has one they would like to sell please let me know.

There are lots of other options if you just want to attach a generic metal gas tank.

Which gas tank was the first to come out; the plastic or the metal?
Are snowblowers with blue plastic tanks newer than those snowblowers with the old metal tanks?
Or are snowblowers with metal tanks a more recent vintage than the older plastic tank models?

I had purchased my YS624T brand new with the plastic tank in December 1989 and had purchased an older 1984/5 YS624T from a business going under in 2001 which had a metal tank. I used it in my back yard for several years and then parted with it because I still had my original Yamaha. Myself, I prefer the looks of the plastic tank model over the steel tank model which is why I would like to find a parts machine or even another one in running condition. Kind of mad at myself for selling the older one it owed me nothing.

Have you done any significant repairs to the snowblower?  Is this gas tank issue the first issue you've run into?

I have owned this YS624 since brand new in 1989 and have never even changed the spark plug or a shear pin. I change the oil every summer and spray rust check in all the body seams. Even the tracks have no signs of wear. It owes me nothing. I have used this little giant for doing not only my driveway but about 3 other neighbours driveways. I wouldn't hesitate at buying the model they sell in Japan if they brought it to Canada. Friends of mine have Honda's and have put repairs into them in the past so I am sold on Yamaha's. Someone told me of a new glue out that gas will not leak through so come summer I will take off the gas tank if I can't buy one and see if I can fix it. Oh and where I live in Ontario WE GET A LOT OF SNOW

Have you found the 6hp model to be strong enough for the snow that you get?  I only ask because I know someone looking to trade his 6hp for an 8hp.  Personally I would prefer a smaller blower (I have the YS-828)  because it would easier to manuever around.  We get a heavy wet icy snow here but total accumulation is less than 5 feet.  Have you ever had an issue with the snowblower's power. Like at the end of the driveway.  
I found a YS-624 that was almost new and stored in the trailer for 20 years. The guy wanted $229 US.
I came really close to buying it but was worried about the hp issue.

I have never had an issue with the horespower. When I purchased the unit I had a small driveway maybe about 30Ft and I was on a main city artery where I had a lot of snowplow crap to deal with and my ys624 chewed it up and spit it out real good. Our snowbanks here are generally about 7-8 feet high on busy streets. My driveway now is 40Ft and is 3 cars wide so I would like a little larger cut. If you don't purchase that 6hp I would surely be interested in it for using around my back yard.
