1998 9.9 2 stroke mercury troubles

[Ian045]

Okay people I’m back again unfortunately, so now I’ve got a brand new carb, fuel filter, and fuel connector. I’m still have extreme trouble getting it to start, again only getting it to run at full throttle. I’ve tried factory carb settings I seen on a video on YouTube and I felt like it wanted to start in neutral but I couldn’t get it to, I tried turning my cam all the way up to get more throttle in neutral. Just trying to get some new ideas and figure something out, thank you.

Is the carb base gasket on correctly?

" new" carb... Factory or Chinese copy ? Factory specs come from a factory service manual, not youtube. If compression is up to specs and spark meets factory specs, you have a fuel issue. Is the carb getting the fuel from the tank and hose ? Many things could be the problem, throwing parts at it won't solve anything. Tests need done to find the problem or we are all just guessing.

I believe so, all the holes lined up for the passageways

It’s is a Factory carb, the guy on YouTube went over the factory specs from the manual (I looked them up to be sure) how do I go about checking compression? And the bulb on my tank will stay tight and I can see the fuel in the filter.
