if your oil smells like fuel, your carb float is sticking and flooding your motor with fuel and will in time or?? ruin your seals and dry out bearings
you need to remove and clean carb and set float!
you also need to change oil/filter ASAP
longer its in there more damage it can do!
adding a booster pack might NOT start your atv, as many times a dead battery when you add a booster pack to it will suck the power down and NOT go to starter and such
I am guessing you did NOT disconnect the batter when trying to jump start it with the booster pack here ?? right??
SO< again, adding a booster pack, doesn't mean your good on enough amp's to try and start things!
NEXT, if you tipped the atv on its rear, HOW Long was it there while running<
you can run these motors that way and RUIN them a s they don't get p[roper lubrication while sitting upright like that, you can starve things from getting oiled!
also, when tipping on its tail, you can for sure shake up the crap in a older fuel tank and thus, send it to your carb and end up with poor or NO running issue's
SO< before cleaning your tank, you MIGHT really want to drain this tank and make sure inside is CLEAN, then clean and make sure peacock is free flowing, and HECK< IMO< since fuel line is cheap,m replace line from tank to carb, this way your 100% sure you have a clean fuel flowing rom tank to carb, into that NEW cleaned carb , other wise you can clean carb and start running and be right back to where your at now!
have to clean up stream, to solve carb problems!
ethanol fuel, coats parts with a varnish like coating that can flake off and clog carbs, and it can build on inside of tank, peacock, fuel line and carb parts!
thus, why I stated, clean tank, peacock, replace fuel line and THEN clean your carb!
GET a good KNOWN battery, and odds are you will be back and running, unless you have motor issue's from running a while on its tail!
