Was running od 97 ttr 2035 pipe,20% byrons seems really good on fuel, but I pulled it out for the main, put my SH in and ran 20 mins no problem.
I need more time with this engine, I have been running SH for 5 years and they dont tune the same. The force would run fine on the box, soon as I got up to speed or went of a jump it would flame at random times, I will get it dialed in this week I have sealed the engine and removed two shims, mabye I should put some sealant around the main needle as well. It has about a gallon in and still has metal pinch when cold.
