Gday Guys,
Thought I should comment on this one as I too have used the same method as Bigted for the Tecumseh Ultima's. I have now re-furbished a fair few of these engines and they have all turned out to be great runners. Only one needed a new carby as it still wouldn�t run right even after I replaced all of the o rings. The last 2 or 3 just needed a good carb clean with new o rings.
I thought for $13 bucks it was worth a shot and the engine is still running spot on. The particular carb I replaced was pretty mangled however I suspect if you replace the o rings in will be a good runner. I think MrKay mentioned that earlier.
Grumpy � the Tecumseh Utimah�s have a remote primer on the side of the engine. Check my previous thread (second picture which Gadge referred to in an earlier post.

In my experience which is only limited these engines when running spot on always start first pull from cold and tear down long grass just like a Good 5hp Briggs Quantum � The quantum is much easier to work on though.
Coopers � If it was my decision I�d go buy the new carb. I think it will keep you mower running well for quite some time to come. Just remember to make sure you keep the oil level correct. Don�t let it run low on these engines otherwise you will get a visitor outside the block (usually a snapped conrod). Ive seen a couple in my travels
