Default Tuned the carb

Ever since getting my build running, I've been having trouble with it being rich everywhere...at idle...at WOT...at cruise. I tuned with screws as best as I can to no avail. Finally, I decided to go back into the carb and see what's going on. Turns out the jets I was running were 76 primary and 85 secondary! Holy cow. I screwed this carb together almost two years ago and I don't know what I was thinking there. So, out the went and now I have 72 primary and 78 secondary. Also checked the squirter size while I was at it and I had 31's. Moved up to 35s and the part throttle hesitation I've been having went away, but the WOT tip in from idle still has a bit of a lurch in it.

The sun was setting so I didn't have time to redo the idle and mixture, they weren't far off when I fired it up. Took it for a run up and down a nearby 4 lane. Man, does this thing rip now. First gear is close to useless (have to peddle it), second gear gets loose, but the feeling of the horsepower pulling past 6,000rpm to 7,000rpm is incredible.

Now to go about fixing that stupid belt squeal. Probably going to delete the tensioner and use the alternator rod from my custom setup.
