Victa Mustang 18 Ultima 4 stroke 5 hp (1994) lawn mower with Tecumseh engine.
I thought the starting problem was fixed by changing the ignition module, but today, after 2 weeks' absence, the same starting problem has reappeared. After priming many times, the engine starts at the first pull, but after having used up the primed gasoline, it stops again after a few seconds. So there still is a gasoline problem somewhere. I took off the carburator and noticed that the gasket between engine and carburetor (the big one) is damaged. Also, the gasket between the carburetor and the air inlet is not perfect any more. The gasket of the floater chamber seems to be ok.
On the carburetor reads 1579H4M.
I plan to clean it outside an then soak it at least overnight in carburetor cleaner liquid and clean it with air as well as possible. But without new gaskets there is no point in trying to fix it.
I searched for parts for this carburetor number without success.
Can anybody give a hint on where to get the gaskets?
Maybe there is a complete carburetor as a complete replacement for this one?
Thanks for any input?
After soaking the carburetor parts overnight in carburetor cleaner, making the gaskets myself from an old gasket material I found, the engine started but then suddenly stopped. After a while it started again, worked as usual a while, and then suddenly stopped again and so on. I assume that the needle in the floater chamber sticks to its seat every now an then.
There are sets with this carburetor and gaskets on sale on ebay, so I ordered one. I will use the lower part with the floater and needle mechanism only, since these carburetors don't have an opening for the crankcase ventilation. I assume that the upper part of my carburetor is ok. A last try.....
