Rover mower throttle assembly
I have a Rover Mower 375 Easy Start Sprint Mower got the plastic carbi with no butterfly problem is someone has been mucking around with the springs on the carbi & I don't know if it should have 1 spring or 2 & I don't know the position on where they should go.` Any help would be greatly appreciated.

Hi! trevormcgarry, welcome to AMHD :)

You'll need to know the engine model number first to download the docs. Owner Manuals - Briggs & Stratton - Austraila - New Zeland Just follow the steps. If you don't know where to look for the numbers, there is a link to the side to help show you where to look. This link is for Europe: Maintenance & Repair - Briggs & Stratton As you know, B&S engines have a spring in the governor arrangement. You want to change tension on the spring to change the speed. (This is basically true of most other small engines as well but the details will differ.) The spring is attached to a metal tung in the linkage at front of motor, this is made of a tinny metal so you can easy bend this tung. To lower speed you want to lessen the tension on the spring. You can do this while the motor is running at top speed but it would be safer to do the bending while mower is not running. By pushing in tung you will lessen top speed gently as it doesn't take much to alter that speed. Often this tung gets knocked in while mowing around bushes or other protruding material and "hey presto" your engine is only idling. It is a design problem that briggs should be working on. Here is a AMHD link with pix's. Its for an easy start 200, but may help: https://www.askmehelpdesk.com/tools-...ly-407490.html K |

Hi, I did actually find a picture of your engine at Briggs: 43.xml - Briggs & Stratton And recently found manuals for Briggs at a site (they and Deere are almost impossible) They are also large if you do not have a good quality connection at high speed and are in Australia. Attached are some pictures. Peace, Clarke |

Ok so basically I know nothing about mowers... my partner asked me to post this because he is a bit stuck putting this mower back together again. We were given it by my dad and it used to be my grandfathers so it's rather old, apparently when it goes, it goes like a dream though... It was...
I have a john deer riding lawn mower, model 115. I have never had any problems with it until today. I started the lawn mower and it was as if the throttle was hung wide open. I don't have a clue as to how to fix it and I know not to run it running this high. Can anyone help?:)
Help! I have a POULAN Lawn Mower that has a Briggs 450 series Engine. It is two weeks old. It starts but will not maintain a throttle. The longer I prime it the longer it runs but or no more than 15 seconds though. What is the problem?
What causes a Briggs and Stratton engine with an automatic throtte control to run too slow and surge?
Hi Everybody, This is my first time to be here joining "askmehelpdesk". My Craftsman lawn mower does not start at all (no any sound when pulling the starting rope). I found the throttle can not be adjusted though the control lever can be set to either "Low" or "High". It seems to me that one...
