Thanks for the input guys, all noted.

The issue i have onb my mind is this is a 30yo Briggs, it needs new rings, plugs, air filter, muffler and a few other odds, it's one of those "idle only" carbs with one screw for adjustment and fixed high speed adjustment, if you tune it for smooth idol you dont get as much power at high revvs, i put a carb kit in it (i think that was around $100) Cost me 100 odd for inlet manifold (my fault, screwed carb on too tight and busted the orig) and didnt make much difference to it. It uses a bit of fuel and oil, so i figure by the time i spend money on all this stuff am i wasting time and money on something that might not last another 12 months, 2 months or 12 years, that is the burning question.

Once again, thanks for your input.
