I had bought this R.V. and have fixed a lot up on it, cause the man I bought it from Lied to me after I purchased it I found out from the previous owners daughter it was unsafe and never meant for the road, but inside was in great shape so I hired 3 different mechanic to do the engine repairs that ripped me off for lots of money, but now that I have found an honest mechanic and he has fixed all the maniacal work on the engine, but we are still having a problem. I had a new carburetor installed 2 barrel, a new fuel pump and all new plugs and wires, new starter, and a lot more checked everything, but it still has no pep to move it tries to but can not do it. I have no Manuel's on it and have done all by ear. If you have any book on one or if you may know what I have not tried yet please will you help me.
