hi Keith ,
some of what im saying probably Gareth might have already told you:
read the bullfinch section of this site,
determine what machine you actually have, a bulldog = oldest, 200 = middle aged to late. does it still have the id plate? the one original plate i own says "howard bullfinch" and underneath "200"
next what engine make and model. it may or may not be original. these are the easiest howard to swap motors on. get advice relevant to your engine. buy a owners manual for your engine, they tell you everything.
general advice always true: electricals need to be clean and corrosion free, good earth between main parts, good insulation on insulated parts, clean points with correct gap - no gap = no spark, wrong gap = one cause of wrong timing and of weak spark, good condensor - they do get fatigued and can be the difference between a weak spark and a strong spark, good coil - coils only really stop working when the insulation breaks down or is injured, of course it also needs good earth and good connections. spinning magnetos / maggy flywheels with the high tension spark plug lead not going to a plug or to earth means the high tension impulse will "find' any weak spot in the coil insulation and can break through causing a permanent leak - look for signs of sparking around coil., good magnets - weak magnets can only generate a weak spark. i know on engine restorer who had to try out 5 flywheels to find one with strong enough magnets to get a good enough spark to get his good engine running. (not an engine ever used on a howard) magnets can be recharged but its best left to the magneto experts. my experience is even most weak magnets will still make a useable spark so that should be a rare problem. even the spark plug can have stopped working! and the lead. 2nd last: dont give up, eventually you will get it fixed. last: tell us all what the problem was...

you now own a real machine, not a digital button box, therefore you will eventually become a mechanic :)

cheers, Rodney
