Just wanted to post a follow up of an additional change I made…

Engagement RPM has always been very low – around 2600 with new stock shoes and springs. This, coupled with the carb issue really made this engine struggle off of the bottom. I machined the shoes and got the weights down to 53 grams each (stock shoe weight is 64 grams). Engagement is now at 3700, and it is a completely different engine off of the bottom. Was considering the new EVO clutch, but with this change I no longer see the need.

Not a new issue – has always struggled off of the line. I took 2 pics, but not sure how to post them here.

Did some testing today…started with air screw at 1/2 turn, and went  in half turn increments to 3 turns with no change whatsoever. Tried the needle in clip in every position – no change. Tried leaner pilots – no change. Tried a new battery – no change. Without feathering the throttle at take-off, it stalled every time.

 

Thanks for the ideas and suggestions,

On the stand, holding the brake and flooring it causes it to stall. I am assuming that it is rich on the bottom – wouldn’t closing the air jet richen it more? I will give it a try though.

Thanks for the reply,

Have been practicing on a short track with Bridgestone YNB’s – just don’t have the MG feel. Might bring a set of MG yellows and their harder compound (used to be whites) as a back up. Thanks Jeremy.
