Diagnosis help! A week ago while on the ride back from work I started to get a loss of power and some weird sounds upon acceleration after stopping at a stop sign. I cranked the gas, it jumped back to power and I kept driving home. Hoping it was just a one time thing ( little hic-up) , yeah right. So two days ago its starts doing it again, but wont hic-up back to normal power. In fact I had to keep it throtlled to 2000 rpms at stops just keep her going. Conked out on me 6 times on the way home. Sound is totally different. No pur, sounds like a fucking outboard motor all of a sudden. Carbs should be fine, did a full re-haul 8 months ago. Have driven it everyday since. Had some battery issues a couple months ago, but that's sorted and shouldn't be related. Pulled plugs just now and they where pretty bad, all black. Am changing the oil now. Any sugestions on where to go from here. Ideas on possible issues please
