Hi All;
I have a 12 hp Tecumseh on a Victa ride on and it's giving me nothing but grief ( I guess that's why the previous owner sold it!).
I thought I had everything that could possibly go wrong sorted and finally got it running but it had me well fooled.
It now pumps copious amounts of oil out of the breather pipe into the air cleaner when it warms up. It looks like it would pump itself dry of oil if I let it.
What would be causing this and how can I fix it?
The previous owner said he had done a valve grind, fitted new gaskets, new rings etc after replacing a dropped rod.
When it wouldn't start for me I checked the valve clearances and the exhaust was at 25 thou!
I reset them at 6 thou and (after I also replaced the broken flywheel key)it started ok.
I pulled the bottom end off (while trying to find the cause of the starting problem) and all looks well but I haven't had the head off it.
Any help would be much appreciated.
Best regards.
Rob.
