ms200t not running right

[chevy]

I rember that it was totaly flat when I put in the new one. How dose yours look like? bent up a little or down or flat? I replaced the impuls line and it runs a bit better but not right yet.

Check your tank vent too.

Yep. The fuel tank vent check valve... or whatever they call it. If the 200 is a newer model, the valve sits in the upper left behind the air cleaner housing. Replace if clogged or just hit it with compressed air. Careful though! Too much and it'll pop apart like a rocket and you'll spend a half hour trying to find the parts. I always check this and the spark screen before investing in a carb kit. Had mine apart just yesterday!

Bent upward a hair just past level. If you go to far it will flood it, you will know right off if you got it right or not.
