i have an '80 and i can get the carb out but not sure about yours. if you get the intake bored out with a dremel and put an estoril on there that thing will fly. my stock carb/bike with a 50 jet got me 35mph with 33 crews speed. get the intake right and rejet you will easily go past that. mine has some kind of issue with fuel flow right now. i am working on it. that's why i know the carb can be taken out.
for those with stock carbs i recommend B12 cleaner, make sure you use glass jar that covers it. you can reuse B12 as all bad stuff, right to the bottom.
i think it is a great 2speed bike. very snappy. but i prefer my batavus over the tomos. am going to be painting tomos and such this winter.
