Hi all,
I have a MF 135 with a standard motor co 4 cylinder petrol engine, it has given good service and is well looked after.
My problem is that it has developed a starts and runs perfectly for 30 to 45 mins then like someone turned on a switch it starts to misfire and splutters and if left will stop
What I have done thus fare to rectify.
- Carby kit (cleaned and checked)
- New distributer Plugs & Leads (Including Coil)
- Had a rattle up the front so new timing chain, governor cup and weights (this removed the rattle and the governor response improved)
- I have changed all the oil, engine, gearbox / transmission
- Reset tappets 010 & 012 so many times.
- Flushed the tank, cleaned the bowl filter and replaced the cork gasket.
- Using 95 Octane ULP with a little valve save added.
- Compression test 145psi all 4 cylinders.
- Oil pressure 60psi
- General running temperature anywhere from 10deg C up to 38deg C (Welcome to Australia), inland location mostly dry with low humidity.
- Ignition timing set at 10deg TDC via flywheel hole, I have not retarded at all.
It has me stumped, all the local mechanics require a laptop to conduct their trade, no real help there.
Any help or advice will be welcome. Thanks in advance,
B
