I have a HR215 that has the 3 speed and it has been flawless since I bought it in 89 . I did take it in for the first time this spring to have a full tune up done . They changed throttle cable which had stretched over the years and wouldn’t run unless it was in full choke. Hopefully yours is something simple these mowers are almost bulletproof. I thought I was paying a lot back in 89 but looking back it was a bargain. To bad Honda is not going to build mowers anymore.
