Stewart will try that later today also will try the ASP/magnum/asp twin needle carb when the exhaust rings come will put on a fiting and run muffler pressure also will pick up some APC props they do a little better than the MAS I think they might be a little easier to peak out the engine the the Sharma carb as is however I still prefer over the paw one be intresting to see how close the standard 15 stacks against the combat tuned version the 09 may be the choice now for the little L19 birddog will run and see what we get wiill run the the PAW19 against the Sharma 19 too be intresting martin
