July 18 Duco cement E 36 Resnot butter F 63 Jeep behaved so poorly yesterday I took it into West River Impl. today for tune up- they found valve burned-out. Mr O. loaned me a car and Jon and I went to Mobridge for parts - luckily got them. Seems I should have tune-up every 203 thousand miles with use we're giving Jeep. This will mess up finances somewhat, but we're lucky we can get it fixed without losing more time. Prob. be able to get it Monday Eve. worked on packing.
