RE: she wont start
Hiya,
100% sure its not the alternator. the alternator is only there to charge the battery. You can run a car without an alternator no problem until your battery dies.
you need 4 things to start it:
1. a starter and battery (obviously that works when it's turning over)
2. fuel
3. spark
4. compression
to 2.
how do you know you have gas ? you can either:
- get rid of aircleaner, push the throttle and see if there's gas coming through
- disconnect the fuel hose from carb and put the hiose into a container (so you don't spill). start engine. does the fuelpump provide you with fuel? take out the petrol filter in carb if you can or make sure it's clean
- try pouring half a shotglas full of petrol into the carb from top. does the sound change when trying to start ?
to 3.
if you have a good known spark plug lying around, connect it to 1st cylinder spark lead. hold thread to engine or ground with electricla plier.
Turn over engine. do you get a spark? if yes: blue or orange ?
to 4. does the engine sound like whop whop whop when starting or is it rather a weeeeeeeehhhhhh ?
measure compression if you have a compression reader
