I am having a starting issue with my lift i have changed the vaporizer/regulator i have changed the "MAP" sensor , i have even changed out the entire throttle body and carb from the intake up. All parts come off a lift that works great other than the motor knocks really bad when started. now on my lift that don't like to start none of this has made a difference in how it starts. i can use starting fluid into the breather at first and it will start and run and will maintain and run great, after i let it set and idle for 15 to 20 minutes i can shut it off and it will start right back up with no problems at all.. i am figuring that there is a valve that should be presenting a little charge of gas to the intake only at start up to help the motor crank but not sure.... can anyone help me out on this?
thanks Chris
