OK heres the deal, I have 2 (tunnelram) list 80186 750 domis (2 circut) and I get a wicked stumble or bog at the hit. Sometimes it works flawless and most of the time it bogs. Even during cruiseing at say 2500-3200 you nail it and it just about dies and you need to work the throttle to get it back. Im tempted to send these carbs out and have then worked being they are older and dont have adustable air bleeds and such. My main goal(like everyone else) is to eliminate the bog. i have played with squirters,cams and it seems to get better but never eliminated. Would it be better to get new carbs or work with what i have and will these work good or is it the wrong application all together. I need to get this squared away before i stap the unit on. Thanks in advance.
