Kink in enrichner hose was the cause of hard starting. I can start it now, effortlessly, on the water
[quote user=Gold Bear uid=4648 fid=29 tid= rid=6]...If the idle mixture screws are to adjusted to far in you will have a hesitation or stumble when you try to get up on a plane, and the engine is also harder to start...I believe your engine will run better when the carb mixture screws are set at 2 turns from lightly seated...[/quote]
Thank you for your help.
Even at two turns out:
When I give it quick throttle it stumbles around 2000rpm and if I continue to give it full throttle it will die. However if I ease it up to 2K and trim up, it will settle in and I can then give it full throttle all the way to 35 mph.
Additional observations:
I have a good stream of tell tale at idle and at slow-medium throttle. Once I get it up to full throttle it becomes a sputtery mist, even stops coming out at all. Then when I let off throttle, smoke is coming out the exhaust It does not smoke like that at slow throttle.. The tell tale stream returns and it is 180°.
