Hi, I bought this old Victa second hand many years back and had very good service from it. Now it does not want to rev up. I have opened and cleaned the carby which has 3 hose pipes on it: One is the fuel supply, another is the vacumm connection to the engine, but the 3rd short pipe, where does it connect??

Also, can somebody explain me the function of the second spark plug on the side of the engine?

Thanks and regards from South Africa.

PD in case you wonder, my nickname comes from my football team in Argentina.

academia,

The second plug on the motor is where the decompressor goes. It would appear that the old decompressor has been damaged and someone used a spark plug to block the hole.

The decompressor only cost about $27-00AU.

I would suggest that you get information from the parts list and manuals area to help with your problem. You could have a damaged diaphragm or missing spring that helps the governor operation.

Thanks Bruce for your prompt answer.

It has run for years without the decompressor (I have no idea what its function was!) and that should not be the problem now.

Both springs are in place in the carby and the diaphragm is ok, in fact when I suck at the hosepipe end the "valve shaped thing" inside the carby opens and closes.

Please tell me how to get information from the parts list and manuals area.

If I may ask again: where does hosepipe no.3 go?

Best regards, Henry.

Henry,

The parts list and manual area is for people that support the board with a donation.

As to the third hose that is for the decompressor and if that has not been connected for some years the bet is that you have had dust go into the cylinder and the rings are worn.

The valve in the carby should be set on "C" if it is a white valve.

Oops, worn rings sound like a major problem.
Let me first put it back together over the weekend and see how it runs. I will aslo close that hose as it feeds directly into the intake.

And I promise, this is my last question:
The valve in the carby is white, but how do I set it to "C"?

PS isn't people sleeping in Aussie land by now?

Academia,

The C is directly over the cut out in the carby. All this information is in the parts list and manuals area.

Hi Bruce, here is my report on the findings during the weekend:

After I refitted the carby with the valve in "C", it would still no rev up. I then decided to look somewhere else, and found that the electronic module had been secured to the body with a pop rivet, this also acting as the electrical connection to ground. Pop rivets do not like high vibrations and as a result it had become loose. When taking the whole thing apart to replace the rivet with a bolt and nut, I noticed the exhaust silencer outlet blocked with oil and dirt. I removed this unit to clean it and saw the engine exhaust manifold almost completely closed with carbon deposits. Cleaned the whole thing, put it back together, and it runs again at high rpm as it used to.
Thanks again for the advice, soon I will be making my donation in order to get the manuals. Bye, Henry.

Academia,

Great to see that you got to the bottom of your problems. I hope that I was of some assistance in helping you.

You will have to keep an eye to the exhaust because it has mesh in it and that will end up closing up the port again. I would suggest that you replace the muffler in the future.

The module would have caused a miss if not properly earthed out but you did no mention anything about a miss in your description before.

Thanks again for sharing your corrections to your machine as I think it will be of great assistance to all the members of the board.

Bruce, you definitely help me in making sure the carby was ok.
I never noticed a miss, that's why I never mentioned it, but thanks to the pop rivet I had to open the whole thing, and as a result I saw the dirty muffler.
I noticed the mesh inside the muffler and it doesn't look too good, I will replace it in the future. Problem here is the price of spares: a primer pump cover costs the equivalent to u$s32, and a diaphragm, u$s 14. Crazy. I'll shop around. Cheers, Henry.

Academia,
