Engine Mechanical / Electrical / Bad idle, and down 500 rpm at WOT
« on: June 11, 2019, 06:38:03 PM »
I have a bad cold idle, and am down about 500rpm, and 10mph at WOT. I do not have a check valve on my Holley 750carb, and have had this issue before, but always had a friend that recently passed on take care of my carb...so I just dropped it off, and got it back- never knowing what was done to it.
Do these symptoms seem like something a blown power valve would cause?
No other changes have been made to the boat.

If it is too high, fuel will still dump into the carb like crazy... RIGHT?
----NO OTHER DAMAGE!!!!
The boat is a 84 BAJA 200ss. Any ideas on where to get one like the one that came with the boat? I am not to hopefull, and will proubly just end up getting 2 new ones so they match.
