Hi All.
I have a 2006 MTD (Model # 13BN771G729) with a 17.5 I/C OHV B&S (Model # 31X707) that has sat for the last 2 years.
I recently got it out of the garage and replaced the battery, fuel filter, spark plug, 93 octane gas and rebuilt the carburetor (Nikki). At 1st the engine was not getting fuel but, I troubleshot this to the 釘ackfire solenoid that is on the bottom of the carburetor bowl. The solenoid functions but, it does not travel enough (when the key is on) to completely dislodge from the bottom of the carburetor float hence, starving the engine of gas. If I back the solenoid out roughly 3 turns the engine fires up and runs like a top.
Now the issue I removed the solenoid and placed a bolt in the bottom of the carburetor bowl. Runs great! I plan to ultimately replace the solenoid. When I engage the mower blades the engine dies if I slowly engage the blade they will begin to turn and I can eventually get them going at full power I put it in gear and the engine dies if I begin to drive. It is almost as if the motor is not running at the proper RPM to turn the blades and/or the axel.
I am unsure what this is related to but, I am thinking that possibly the 釘ackfire solenoid does more than I think and/or I messed up the throttle linkage when I was rebuilding the carburetor (ie. throttle assembly on engine, linkage and/or spring that connects to carburetor, etc.).
Any ideas? Thanks in advance.
