Small Engine Problems? Ask an Engine Mechanic for Answers ASAP
Hello, welcome to the Technical section in JustAnswer; my name is ***** ***** I will help you today.I'm sorry that you've had to wait for a technical response. The current question volume is unprecedented. Not only are fewer experts available to respond at the moment, but there are more questions from people being at home in isolation. Hence we are extremely busy. Please give us a little bit of latitude in response time. _____Please can you outline what you did to the carburettor?_____If you receive a phone call offer, please ignore it - these are system generated and outside my control. My understanding is that you won't be charged if there's no phone call.
What was the original symptom that led you to clean the carburettor?
I should have asked you earlier: what colour is the smoke that it's belching?I presume the smoke is coming from the exhaust?
By any chance did the mower have an extended period of being laid up?
I don’t have any good news for you. The best I can hope is that the cause is nothing more than a worn valve guide. I don’t want to be a doom-monger, but in the list of potential problems are worse things, such as a worn/broken piston ring, a worn cylinder, and a cracked piston. A compression test would help confirm an internal engine problem before taking the step of stripping down, but I think you’ll end up taking the head off to investigate.
Hello, how are you getting on with your Mountfield?
Hi Barney, you can’t cancel the trial - the topic is still here, as you can see. Was there something about my assistance that meant you didn’t want to give me a rating?
