been having a weird sticking issue on my scooter since i got it, seems the carb gets some gunk in it every 3 or 4 months. so during my cleaning i decided to see what the main jet was and once it was out there was no identifying numbers on it? would any one kno what the stock would be? ive seen them be all over like 100-110 ish
this is a walbro carb so i assume a decent carb?

Should be a 110 main and a 35 pilot jet idle . But if you have done any serious mods exhaust pod filter you might go two points up on main again and see how it acts i have no idea of your elevation. Every motor is different but this is a base line or if it's a 125cc the main should be 108 . That gunk issue is only coming from one place your tank , clean it and install a automotive grade fuel filter and new lines i have seen rubber lines deteriorate inside and leave fragments in the carb.

A #60 - #80 drillbit set (micromark.com) serves nicely as jet gauges. Obviously use the dull end.

That gunk issue is only coming from one place your tank , clean it and install a automotive grade fuel filter and new lines i have seen rubber lines deteriorate inside and leave fragments in the carb. how would it be coming from my tank? in my experience with any motorcycle it be airfilter. no mods done just a stock 150 some one drilled a center hole in the stock filter that i patched up recently this week so we will see if it fixes it. my gas tank is brand new and just installed so it shouldnt be that. just got a 2 gallon tank lol makes it a lot nicer for long trips. ive had a lot of 150s and never have had the same main jet in them ive had anything from 100 to a 115 in a stock 150, also would any one kno what size? these are bigger then the 50cc ones i have seen and thats all i seem to find on ebay. feel like im running a lil rich. also just found a small leak were the lil on/off valve thing is connect the tank to the petcock. im in michigan also so no elevation but i did notice when cleaning the carb the needle was all the way down so i moved it up 1 notch. appreciate all the info. |
