In checking engine clearance, when I placed the two shaped yellow engine mount blocks on the airplane, I found out my engine (Rossi 60) won't clear. I'm going to have to put two 1/4" spacers under those block to get minimal clearance. Anybody else have this problem? Also, in adding the spacers, I'm hoping I don't have a fuel draw problem. Will have to see how high I can go with the tank. Any experiances anybody has had with this problem, I'd be interested in hearing how you rectified the situation. Thanks Joe
