vanguard carb swap questions

My 18hp carb is junk can I use a 16hp carb in its place and change jets ?

[Nubs]

Yep

[brian v]

OK thanks I found a 16hp carb on eBay but I have had no luck finding an used 18hp carb

[Nubs]

Many times the 16hp carbs run the same size jets, can't tell Ya why

I would hold off on that deal for a bit, let me look and see what I have first, thinkin' I have something. I will look in a few hrs and if I do i'll post a picture and we'll go from there.

OK I got a carb that works engine runs but under full throttle the flex pipe to the muffler glows red is that normal ? Or am I to lean on the main jet thanks

[Nubs]

the color of the spark plugs is the only way to know for sure, dark brown to light tan is good. gray or white and its to lean, flex piping likes to hold heat.
