reviews

Helmuth is a great merchant, easy to place orders, received confirmation in a few minutes, received update to shipped status with tracking #'s in about 2-1/2 hrs, and was quickly followed by a notification of shipment by FedEx. They were a pleasure to do business with!!

Andy Ferguson

Helmuth had a reasonable price on Honda engines and a great warranty. They provided quick shipping, and we are very pleased. Thank You!

I was a first time buyer, but it wont be the last. I talked to the owner and he was very nice, helpful, and had exactly what i wanted in stock. Good man and a good company that do business like it should be done. That's getting to be uncommon. I appreciate that and I wont forget it. Helmuth Repair is now my go-to source. Thanks, man!
