I realized I should probably be in this forum for my problem. I had some great replies last night. I definitely have oil over the fill line. Gas smell in the crankcase. It leaked from what looks like the upper transmission cover on the inside which trickled down to the oil pan. This all happened after I filled the tank for the first(new, used owner that I am)time to capacity. The gentlemen last night said its probably the petcock. Is that the only reason for this? Thanks

Fuel back-flowing down the petcock vacuum line and into the carbs/cylinders/crankcase is a common failure. Weak float needles are another, particularly if the petcock is set to the Prime position, where fuel pressure on the needles never stops.Ed
To measure is to know.

Check on Ebay under Georgefix for a good deal on a new petcock. And for Gawd's sake don't run it with gas in the oil. Change the oil and run it for around 50 km and then do it again with a new filter. This is all after installing the new petcock. Don't bother with a rebuild kit, they don't work.....Comment

gas in oil
Thanks for your reply. So you believe its the petcock and not the faulty float needle?Comment

The float needle can't leak if there's nothing to leak, with a good petcock the fuel is completely shut off when the engine isn't running. There are two paths for leakage, one is the vacuum line as Ed mentioned, the other is past the float needle, but niether one occurs with a functioning petcock.
The purpose of the needle valve is to control the level of fuel in the bowl when the engine is running, it is not it's job to hold back the fuel when it's not running. The fact that it will sometimes has nothing to do with it. Replace the petcock, change the oil, and get on with the rest of the list of neglected maintenance.Comment

Which Gearge is the liar that used to say he could synch the carburetors and fine tune them on his engine so you don't have to?
George A or George B?Comment
