spark plug gets soaked...why?

[tosAnutter]

hello, been working on rebuilding my first blaster..it has been bored over .40 has a full fmf exhaust and im running stock airbox with cover..also has vitos 2 stage reeds...my question is what jetting should i go with? it s cold outside as well? it will only run for about 10 seconds before flooding itself out..ive cleaned carb several times and have another carb ive tried and have gotten same results..i dont have a jet kit in yet as far as i know...does anyone know the stock size jets and needle that should be in there? i have 3 carbs, i suspect one may jetted already but will have to check sizes tomm. to see if all 3 are same size or if there is a diff in size....any thoughts on it flooding? is this typical of not being jetted? its been about 35 degrees outside as well.

stock main is a 230 or 240......ur stock pilot is a 32.5......it shouldnt be overloading unless something is sticking in the carb

float in the bowl sticking or need adjustment (hieght)?

yeah, being cold should actually make it leaner, so it can't be that. Definitey sounds like you are flooding out. It is unlikely (but not impossible) that all of your carbs have the float set too high, but it is certainly possible that they all have bad needle/seat assemblies.

One thing you might try, to compensate for the extra fuel, is take off the airbox lid. This would be temporary since you probably aren't jetted for the extra air, but if you take it off and it runs longer/better then you know you are on the right track.

well i just set everything back to stock, stock exhaust and piston....seems to run good now...little boggy on top end but runs better then before...made no changes to carb...i assume its a jetting issue...i guess i should buy the kit now and experiement a little...least i know it runs and im on the right track! thanks guys
