Re: 200xp only WOT when primer is held in

I think you should take the "Hint" that everyone has given you so far that you do not want to hear.
Rebuild the carb's
If you know better then do not post asking for advice.

To anyone who reads this post please disregard all of the useless advice given above.
The CARBS ARE IN PERFECT CONDITION EVEN AFTER NEAR 20 YEARS. An outboard will not run on zero fuel pressure. The 3 lb minimum is there for a reason, those so called gravity feed carbs can't gravity feed when the tank is below them. But anyway there is a limiting circut in the VRO that keeps constant 4 to 5 psi on the carb float bowls. If you dont have that when running, it will seem like all kinds of things are wrong. Mine is running great now and it only cost me a mere 101.97 for a new pump. Have a nice day wonder techs. Also to those who stumble upon this post. I found http://forums.screamandfly.com/forums/ to be a much more educated group of people with more educated answers. In short if you think you may be missing or running out of fuel go to your auto parts store get a 15 dollar fuel pressure gauge plumb it in on the output of the vro at the top and at idle it should be min. 3 psi no fluttering and at WOT it should be 4 to 5 psi with very little flutter. Troubleshooting is simple just do it with a little common sense.

I don't consider myself a wonder tech. But we did get a lot of confusing information, like fuel increasing out of the high speed nozzle when using the primer. Follow the feed lines from the primer to the back side of the carb, and explain to me how it could do that. You did'nt mention any tests, pressure, vacuam, but you did want someone to set back, and quess with you.

I did a search on S/F and couldn't find your thread to see the answer you received there. Please let us know what name you used, or link the thread.

Had you done a pressure test on the fuel pump, you would have found the advise from screamanddream a little off with that 4-5 lbs., but then, they can wring 70-80 miles per hour out of most any Merc. What kind of figures are you getting from that $loo VRO? How much oil is it delivering in 5-6 pulses. You do know how to test that, don't you

I wasn't able to find his thread on S&F, did you? From his response to us, it seems he still doesn't understand how the fuel pump, floats and carb work together. He also told us the fuel pump had been disassembled and was working correctly in the first post.
