U don't have to go to him he will ship it to u.
I had the pleasure of driving down to him from Liverpool a few weeks back, I bought a new pump from him an wanted him to fit it.
I have a honda gx390 21 lpm, and like yaself I took advise from people on here, will be coming upto 2 years in march and was a great investment.
If u speak with him ask him which engine is the quietest, as noise is an issue, there may not be much but there may just be.
