Lawnmower engine problems

Had a day off on Tuesday as the plasterer was working at home. Took the opportunity to have a go at my petrol Flymo (engine content).
Simple job I thought, just a carb clean out needed. A job I have done before quite a few times. It's also a good opportunity to clear out all the bits of grass etc that collect where they shouldn't. The carb clean went OK till I came to replace it. I must have finished the job 4 or 5 times. Each time, there was another bit left over that I should have put back. The final straw was when the throttle governor spring broke. I had already dropped it in the grass once and considered myself lucky to have found it. This time there was no chance of repairing it. Every time I bent a new end, it snapped again. A new one was ordered and should be here today. Then I noticed that the engine was loose. The mounting bolts are above the fan so that and the blade had to come off. No matter how I tried, the centre bolt would not shift. After over an hour trying, I finally had to resort to the cutting gas to take the head off. Once that was done, the rest screwed out by hand. Tightened the engine bolts OK and ordered a new blade bolt yesterday. Wondering why the old bolt was so tight, I remembered an incident about 2 years ago when the blade hit something and stalled the engine in about 1/2 a rev (literally). That must have given the bolt an almighty tweak. It's a very fine thread on those as well. What did it hit? Well I was very glad I was wearing steel toe caps that day. Should have the thing working tonight then the lawn can get cut again.

If you can't get it going, see if you can borrow a caravan, huge awning and a couple of tents, then take the family for a free weekend holiday in Burford!
(Sorry, could not resist that!)

Bad news in that respect, I got the bits, fitted them and (eventually) it worked. I now have some lawn again. What's all that about a free weekend? You must have seen me at shows before then. My "normal" rally engine is an ex lawnmower lump. If anyone is at Honiton Hill, look me up and you can admire an engine that's different from all the others.
