I'm having an issue with accelerating slowly the engine dies. If i go from idle to full throttle it takes off most of the time. I've replaced the coil and a part a friend of mine called a switch box no improvement. If i was working on a old car i would replace the accelerator pump thats what it feels like. HELP!!!

May need to remove and clean carbs and resync linkage.

Do you think cleaning them will do the trick or will i need to rebuild them? How hard is it to resync the carbs?

Wont know until you take them apart, service manual has link and sync procedures.

What i'm looking for exactly? Will they be gummed up or varnish
Thanks

Could have varnish, but you may not see the problem, you should verify every air/fuel passage is clear from debri. Best method is with a spray.
