no question, started much faster immediately. my boat's been sitting idle since end of July last year, did not get out again, covered it up, drained all the water out of block and manifold and it sat for nearly 10 months... so, bought the conversion kit, had friend help me, he's the head GM mechanic at local dealership, put in unit, had to dump some gas down the carb, fired it up, adjusted a bit... will finish adjustments wed this week. one bump of key and boom, with points would take several turns.. it's clearly running stronger with same fuel supply set up used for points.. idle adjustment mostly... looking forward to seeing how long this unit will stay working properly.... until now every year had to buy new points and mess with that, will keep the points in the boat just in case..
