How much money are you paying for this? 130 hours is quite a few really. If you have access to a compression checker, I would take it with and check compression on both sides. Look for 120ps+ or right around there. Ask him if he has lubed the bearings etc, and how often, he should have done it regularly, at least before season starts and probably several times a season if it has gotten that many hours in 2 years. Ask him how many times he has changed the oil and about general maintenance, such as if he has put stabil or fuel stabilizer in the gas before storage. Look at the engine wiring and fuel lines etc, check to see if they are weathered, cracked, splitting, etc. Take a good look at the prop, it should still have a good cup on it. You may also want to find out what the diameter of the prop that came on it was brand new, and measure the prop to see if it has worn down much, a prop for these isn't cheap! Kinda like buying a 1,000 dollar car and then having to put 600 dollars of tires on it right away. Look for rust and general wear. Like I said, 130 hours is quite a bit but these things can take it easily if they are well maintained, hell look at a lawnmower engine (which is basically what these are). A buddy's dad had a coast to coast lawnmower for 22 years, figure mowing the yard took 2 hours (conservative), 1 or 2 times a week for 8 months a year. Thats 2(hrs)x1.5(times/week)x32(weeks/yr)x22(yrs)= 2,112 hours. Never more than stabil and oil changes, and the thing was still running when he threw it away. Anyways, look it over good, you should be able to tell if it was taken care of or abused, just like a car.
