Initially introduced to the market approximately five years ago, four-cycle engine tampers claimed to perform like two-cycle engine units, while offering greater convenience and lower emissions. Unfortunately, as Smith and many others soon found out, the first attempts at melding tampers and four-cycle engine technology didn't live up to manufacturers' promises.
"They were just too new," said Smith. "Though the four-cycle engines offered the convenience of not having to mix oil and gas, the design just wasn't there. The tampers didn't offer the power or durability of the available two-cycle units."
Another problem with early four-cycle engine tamper attempts was a tendency to leak oil. Early units could not be transported on their sides, nor be operated at an angle. Doing so would result in oil leaking into the cylinder, carburetor and other sensitive components, causing the engine to seize or fail to start and eventually resulting in more work for Smith. Thus, knowing that four-cycle engine tampers had some major performance and maintenance issues to address, Q&D decided to stick with proven two-cycle technology until something better presented itself. That "something" was introduced in a phone call last year.
