hey awhile back I was having some carb problems with my casal. I asked everyone there openion and most everyone asked me to give them jet size carb size al that stuff and I being blind never even saw there wasa number stamped ontehse things... I was cleaning the carb agian today and check it with a microscope.. the casal has a 17mm Carb
with a number 70 jet in it. The problem I am having is that the bottom of the tank was super clea becuase it has had half a tank of gas in it for quiet sometime... and until it ran out i didn't have any problems... however I have filled up the tank completly and dirst and light rust has gotten mixed in teh with the gas and i keep on crudding uot everything.
I took off the petcock and flush it with water for ever.. it looks alot cleaner... the rust almost felt just like dust not actualy rusty or anything... and then I plugged the hole and poured in a gallon of oil 30 wieght to get the rest of the rust out and tolubricate and elimite any water so re rusting doens't occur. then drained that..I just put in normal gas and oil mixture and installed a new in-line filter from a motorcross shop.
I hope this helps me... (it was a bitchg etting all the fluid out of the tank.. had to use a small hand vaccum pump for some of it)
what do you guys think about that carb size.. seems pretty big compared to alot of the ones i've ehard.
It says to use a mixture of 30 to 1... how many of onces of oil is that per gallon.. I suck with math?
And abuot it smoking it says it could be from the primer being stuck down some... maybe this was due to the trash in the carb? I dunno.. hasn't seen 40 in a while... I gotta get it back up that high... that was great.
