Hi. My generator packed up in my 71 semi auto 1600 so I replaced it with an Alternator. Unfortunately the throttle levers didn't clear the alternator so I have made a 25mm spacer for under the carb and now the throttle levers just clear. It's taken me about 6 weeks between getting the alternator in and wired and making the aluminium spacer. Got it finished tonight and it fired up first pop, but I've noticed that the engine sounds different almost like a muffler hole.
My first question is, could adding the spacer make the engine sound different?
My second is, should I need to re-tune? Just done it a little while ago.
And third, the engine lid only just shuts. It whacks on the old oil bath air filter and even popped out my flash as chrome 'automatic' sign. It is banging right on the top lip of the filter and is the one with a big round bit at the top. Should I get one of those oil-less small round air filters? or whack the side of the air filter in, or something else? Thanks guys. Andrew NZ`
