Is my lawnmower about to blow up?
First stage - lawmower started cutting out for no reason - I looked at solutions, cleaned the carburettor (with carb cleaner) and it ran slowly and unevenly eventually cutting out.
Second stage - I gave the carb a second more thorough clean with carb cleaner and WD40.
This time the engine started faster and louder than I can ever remember it being (I’ve had it some years so it might have been gently reducing speed in that time). After 3 minutes there was smoke coming from it and I lost my courage and stopped using it. Admittedly there is a chance the smoke was just old oil and petrol on the outside of the mower during the clean but before I use it again I’d like to know if I might have done anything to cause the mower to run too hot.
The Lawnmower is a Mccullough Vantage 55; the engine a Tecsumeh
Thoughts most welcome.
