The is the "infamous" P...100 sport, my mecanic has replaced the tank, spark plug is new and working, coil is new and working, battery is new and working as well, he has taken the carb apart and cleaned it, gas oil ratio is correct but here's the rub, it will push start and when started and given gas it bogs, he cannot kick start it.. I figured someone here would suggest soemthing we have not tried....And by the way, you were all right on the bodge, I purchase I am really regretting....Tkanks again...

What does the plug look like after a few goes at kick starting, or after bump starting and giving it some throttle?

If i had to guess ...

if it won't start by kickstarting, but will start by bump starting? It MIGHT be worn clutch plates... might be low compression do to an old top-end.

The fact that it bogs when you give it gas i'd wager is a separate problem. Your idle jet is the right size but your main jet or mixer / atomizer is clogged or too small.
