Exmark lazer z e series right hand motion control lever issue

[heloduby10]

Recently purchased a exmark lazer z e series, 60” deck with the Kawasaki engine. Seems to be a good mower however there does appear to be a manufactures defect concerning the right hand motion control lever. The lever is prohibited from going full forward due to the spring-leaf hitting the control lever frame box. The dealer made adjustments so the mower would track correctly however now the mower will not operate at full power. Has anyone else experienced this issue?
