Briggs & Stratton 3.5 .
Just lost loads of power. Intermittent splutter under no load.
Tried fresh petrol, thorough cleaning of air filter, cleaned spark plug, fat spark, replaced spark plug. Seems to have plenty of compession.... Oil is clean ( replaced every season and is at correct levels. Does smoke on startup ( well, it always did since new). And now smokes a bit more than I remember... Gummed rings? Any quick and dirty solutions? (i'd have been tempted to bung in some ether to free it up but I remembered that the 2l bottle of ether I had was more than
20 yrs old .. and old ether can decompose explosively. So I disposed of the ether ecologically (pour over weeds gently, move car (I know that was the wrong order now), throw match.. Well, ethers organic isn't it?The fuelling system is new to me - it seems to have an oil feed into the (carb? drip feed petrol thingy - the carbs on my old Cossack Ur(in)al seem futuristic compared to that...)
Anything obvoius I should check ( I've had almost all my spanners hijacked by my brother for his new motorcycle project - he left me three big imperial spanners, a 22mm deep socket, a torque wrench, my second best impact driver and one set of imperial feeler gauges - he even took my WD40... - teach me to go into into hospital... I'm going to have to go to the auction houses as on past experience I'll never see them again. Why he felt the need to take the Ducati thing extractor I'll never know....)
Bum.
