Hi Glenn,
Thanks for your reply. I will check the carby and exhaust port tonight or tomorrow.
I have a 30 c.c. lawn mover engine which has wallbro carby as well
. I might want to bring that to the field next time and see what this engine does with the carby.
will definitely post updates here once I have got a chance to try out.
good luck with your new dummy fitting!
cheers
Lawrence
