Well I have been away for a little bit, but thought I would drop in and give a little update. I have been pretty busy with the "honey do" list and havent had much time to work on the Scrambler. Well I was able to get the adapter plate, and mounted up the MC2100. When I first started it up it had a really high idle, wouldnt go under 2000 rpm. I knew I had a vacume leak somewhere but just put it on the back burner until I had a chance to investigate. When it was running the throttle response was amazing though, even a poorly adjusted vacume leaking replacement was 100 times better than the gummed up stocker haha.
Well last night I decided enough was enough so I bought a rebuild kit for the carb and went to town. I found that the base gasket for the carb was the incorrect size and left a gap causing my massive vacume leak. I will throw her back on tonight and see if I can actually get the idle to tame down a bit.
