good carbs... the 32 on the TTR was a bit finiky to get the jetting right
I found the easyest way was to plug the power jet tube while getting the
jets right.. then reconnect it then you were pretty close with the jets..
I prob had it right 10 times... but yer always think one bigger or smaller
move the needle... will be better....maybe I just don't know when to stop fiddling...
The one on the Montesa came pre-jetted from Sammy Millers classic trials in the UK
so that one was easy... plug & play...

Thanks for the advice with the power jet, that's a good idea to eliminate that variable. Honestly, my biggest hurdle is to figure out is what jets to start with. I can always go on the "definitely too rich" side, Thankfully the pilot circuit should be the easy one. A 40 is going to be close lol.
