Hey guys my brother in law has an ms291 that wasn't running very well and I pressure/vacuum tested it and found a torn intake boot but also I'm only getting 73 psi of compression. My question is can the ms391 or even the ms 311 p/c be installed on it just the same as the 290 to 390 conversion?appreciate the knowledge and input.
