Vacation is over... bad acceleration

I'm pulling carbs this week (just order a rebuild kit for the fuel accelerator). Problem happened about 5 miles after filling up. Gas was/is suspect, so the carbs are coming apart. Being that I only cleaned the carbs once before, this is a good opportunity to inspect all the pieces for real this time.bountyhunter wrote:

I took a long vacation from wrenching after some new problems came up at the end of last year. My 79/650/B3 was running tops all of last year until about 15 miles into a ride, going about 40-mph the motor started to slightly surge. ?
thanks

Be sure to clean all the crud out of the tank and petcock assembly and install good filters or cleaning carbs becomes a permanent hobby.LineArtist wrote:

Everyone seems to be stuck on fuel as being the issue....then how come the engine runs like a kitten when not under load? :huh: Mind you, all their suggestions are definitely worth doing anyway under the "general maintenance" flag

Points and Timing - having numerous issues dialing in the timing and dwell. Will start chasing wires and voltage through the system and most likely changing over to a Dyna S (DS2-2) setup with 3.0 coils once the issue is sorted.
Suspect bad coils or lack of power at the points.

Exhaust side of the #2 plunger, most likely will keep me up at night until I sort what happened here.

Go borrow or rent a compression gauge and crank that thing over a few times to see where you are....

Based on the visual of that slider, and perhaps a bent or burned valve... how would the bike/engine behave?
