yea,the burbleing sound bad but i am not going to worry about it too much if mine starts to do that,i think the most important thing is that the engine performs and not quit in flight,i can deal with the burble just fine,i know it may be anoing but as long as my plane remains in the air and comes home in one pice with out any mishaps,im happy,anyway i finaly got some lawn boy oil,they had it at the true value store about 4 miles from home,i never even thought about cheking there till i spoke to a good friend of mine,

so i guess ill lay off the briggs and stratton and go with lawn boy,i am just going to break in the engine in the air,will take real easy on the first three gallons of fuel,i just have to wait for an oportunity,they're having a flying at the fiel this weekend so no chance to fly till maybe the following weekend after that,so we'll see how it goes,Geppino your plane is well seasoned at 100 flights,you may be due for a new one, maybe a christein eagle,that would be nice,well once i get serious with this plane,i will be geting an extra 260,that would be great for me,i wouldnt want to get too oversize since i dont want to have to buy a trailer to haul it,my pickup truck will do just fine foe a 25% to a 33% plane
