Briggs & Stratton Lawnmower Primer Bulb Issue Won't Prime & Will Not Cold Start - How To Fix

🔧🔧 DrewFixIt STORE: www.drewfixit.com 🔧🔧
If you've reading this, then it's likely that your push lawn mower only starts when you spray fuel, carburettor cleaner or brake cleaner into your carburettor. Then it runs fine!!
In this video I am working on a Rover Lawnmower with a 4 Stroke Briggs & Stratton Engine and it has exactly this symptom where it will not start unless you spray starting fluid into the carburettor!
In this short and easy to follow DIY video I show you how you to diagnose the issue and how you yourself can get your mower back to starting like new!
This is where you can purchase (relatively cheaply) the gaskets that I used:
Amazon (US and General): amzn.to/3L4bI9F
Amazon (Australia): amzn.to/3xDw1YB

I've been waiting for ages for one of your lawn mower videos, love them. Keep em coming 😁

[@DrewFixIt]

Hi Mat, there’s plenty more great content to come too!!! Cheers Drew

I have the same mower. New carby, new primer base, new primer, two gaskets and still won’t prime? Any ideas?

[@DrewFixIt]

Did you try and spray Carby cleaner into the vent hole in the Carby like I demonstrated to see if it will prime like that? Cheers Drew

[@Rslibertyturbo]

@@DrewFixIt yeah I did and spray through the like you did, still won’t prime though

[@Rslibertyturbo]

Turns out it won’t prime with the cheap Chinese carby, put the genuine Briggs and Stratton carby back on, sprayed through the hole. Used to two gaskets and new primer base and primer and now it works, thank you! I am so tempted to buy auto choke Briggs and Stratton now😅
