Honda rotavator; totally flummoxed!!!
What ho one and all,
I have a Honda FG110 rotavator with a GX25 engine that will not start. I have tried everything and am totally flummoxed.
Replaced carb parts with a repair kit
Replaced complete carb (albeit with a Chinese one!!)
Replaced ignition coil
Replaced spark plug
Checked for spark at spark plug
Removed top cover to check that timing mark is at TDC
Checked that timing marks (crankshaft and valves) line up correctly
Checked the clutch key (it is moulded into the flywheel so not replaceable but it is not damaged)
Checked spark plug and ignition magnet gap and reset
Tried with both new fuel and Aspen fuel
Checked the exhaust is not blocked
It seems to be 'trying' to start which leads me to think the timing is not correct but all the timing marks line up.
Throw it away or take to a stealer for an expensive fix are not really on the cards. What is next?
Any suggestions will be gratefully taken on board.
