One more problem with the right hand crank case cover that I ordered. It was only the 'right hand crank case cover' and none of the pressed in parts came with it. I look at pictures and the pressed in tube for venting shows up in and the pressed in water tube also shows up as already pressed in. But neither is in the part I received.

I managed to be able to twist and pull the air vent tube, about 3/16 diameter, and was able to pound it into the new casting. I definitely got it passed the inside surface but stopped the pounding before I did bend or crack the new casting.

Now I am trying to get the water hose connection out of the top of the casting. Sure can not get it to budge one bit. Nor have I been able to find any offered for sale.

I will try to loosen it with a torch on the outside and see if then I can twist it up and out. If not I will try drilling along side and see if that helps.

I would prefer just to buy a new tube and try to get it pushed into the new casting someway. Maybe a bit of enlarging of the hole or sanding the outside of the tube or both. It does not need a major force fit to hold it in. Just a nice grip and some adhesive will do fine.

Anyone know of a way to get this tube for the water hose? I spent a lot of time this afternoon and found none.

That does make sense to me so I asked. What type would you use for this job. I would like something thin and at least an hour or two working life include. I have several in the garage but will look to the auto adhesives for one that gives sufficient working time and can take a lot of heat too and is easy to apply to one side only and the outer side could be covered later as the job goes on.

I know how I work and once started I want to have time to put all those bolts in while the adhesive is still soft and willing to hold on to stuff. I am not as fast as a factory worker might be with an array of properly fitted air drive tools.

I will just advise to let Alleyoop help you as he has helped me a lot.

It would be helpful to tell us if horizontal Honda engine or vertical Linhai engine. As Alleyoop has advised the same carb is used on both but after that much can be different. Examples might be the covers will have some differences and especially under the seat items. Doing the valves on a Honda is much easier and more direct to get too than the Linhai.

The actual horse power of the Honda is less than the Linhai. The 250cc is a generic number used by a range of actual outputs.

My scoot is the Honda and I have been working with it for quite a while now. Had some real problems like boiling over so had to replace the thermostat and fan controller. Then had problems similar to what you are claiming. I changed the carbs but no advantage and went back to the original carb. Many problems I have had were due to the air system to the engine. It must be good from the intake box all the way to the carb. Nice fitting connectors with no extraneous air leaks. I did replace the air tube from the air intake box to the carb. Be sure they fittings are completely fitted and the clamps tightened well. I put a new fitting on the back of the carb to the engine intake port also.

As soon as I get my scoot running I will take a few rides around town to make sure, then it will go on sale. I am now climbing the hill towards 83 and my better half is wanting me to let go before I do something dumb, as older folks do things.

Fix and learn and then ride.

Thanks for the film Alleyoop. That sure clears up a couple things for me. One important one is the sealer. While cleaning the seal area this morning I found stuff scraping off the casting in that area and was going to ask about it. He said RTV Sealant, so tomorrow I will go to the auto store and buy some. He did not say what type but I am sure the auto store folks will know.

Now on the oil seal he did show how to remove and replace it. But for my engine with only 240 miles on it should I really bother to replace the seal at this time? And would my oil be messed up with all this water leaking I have had. I suppose an oil change would not be such a problem, just wondering if my oil got full of water.

And thanks again for this film. I apparently did nothing wrong while getting my seals out.

The smaller seal they sent me is 3/8ID X 3/4OD x 3/16 thick. No room for that in my impeller as the large seal with the white face is 1/2id x 7/8od x 3/16 thick. One or the other but not both.

I have had water dripping from the weep hole under neath the pump so I decided to replace the seals inside the pump. Ordered some and put them in yesterday. But now it is like pouring water in the inlet pipe and watching it all run out the bottom. No slow down at all.

So what is the problem?

I ordered the following parts from "Partsforchinesescooters.com".

Items 2528 and 2529

For some reason I could not get an image to copy and paste here. Link to the page, type in 'water pump seals', and see the items I selected. They do look much like what I pulled out but now are worse than before.
