I had humongous problems with them. They(Paul) told me to bring engine on over for overhaul. Had the shop in St Louis rush pulling the engine and I delivered it myself. Immediately after, Paul closed shop and took off to Arizona for 2 months. Finally rebuilt it after 4 months and price was twice his quote. Also, shop in St Louis installed engine but no start. They spent extra hours diagnosing issue and finally found mags were out of time so they wound up changing spark plug wires to get it to run. NEVER EVER deal with them shade tree mechanics again.
