That works .
Could also add a compression spring between the brass fitting and throttle arm .
Or make a extension/L bracket off the tank mount for the return spring .
Anyone know of any builders providing blueprinting, performance mods, etc on these little 79cc engines? I'm only aware of Shane at AGK and DGRE8926 on eBaY (whoever they are), https://www.ebay.com/usr/dgre8926. Not looking for Amazon bolt on parts or "stage" kits, more interested in finding an experienced builder who has experience with these engines hopefully on their dyno. If anyone can tell me who the eBaY engine builder is or provide other references it would be greatly appreciated.
