Hi,
Thought I would give an update on my issues with this engine, as I got it working last weekend.
-Tested the compression by spinning it backwards with pull starter removed and got it to bounce so compression okay.
-Fitted a new spark plug but that didn't help.
-Checked the spark distance and got an easy spark at 10mm gap so thought ignition must be okay.
-With Bonner Bloke's comments in mind (1st reply) I decided to dismantle the carb again even thought it was in very good condition and all gaskets had been replaced by me. Whilst removing carb I noticed that the small carb-to-head gasket had swung down out of position from the top screw when I had refitted it in March, after putting in the new gaskets. This would have been a massive vacuum leak and prevented the carb drawing up any fuel except once running. This issue had occurred in March before I had inserted the bottom screw and tightened both screws up and I hadn't noticed it then or since. With this rectified the engine started first time on the choke!!! Deep joy.
Problem now is that later in the day, when having another go at starting, the engine stalled with the choke pulled right out and kicked backwards breaking the pull rope. Not sure how common a problem this is but if it happens once I hand it back to my wife's friend she will be stuck. Any comments on how likely this is and what to do to avoid it. The original old rope was a bit on the short side but not sure this would make it more likely to break. Should the rope be strong enough to resist a kickback like this??
Thanks
