I have a '95 2.5 / 200 that someone hacked up the carbs on. For some reason unknown to me the carbs will not let fuel through (at all) if the engine is sitting for just a few hours. I have to blow out all the feul in the carbs with an airline to open them up. Once this is done they run great all day long - until I shut it down for a few hours then it won't let fuel through again. It seems that these carbs had the diaphram mech. pump on the side that someone cut off & blocked up th opening. How can they be running fine all day long like this? I need to replace these carbs but I don't know what to look for. The engine is running 7500 - 7800 r.p.m. with 33 cc heads & 7 pedal horizontal reeds. I use a holly blue fuel pump. Can anyone suggest what carbs to look for? & does anyone have them for sale?
Thanks for your help.

WH-20's, 22's, or 15's will work well with 2.5...I have a set of Cottman Yamaha's built for a 2.5, 300drag...they will not work with a 2.0, really don't know why, but 7800 iz max rpm with a 2.0...

That weiney motor wont flow enough for those carbs. that's why. they might work well on the 2.5 200 or you might have the same problem. You need to ask Kottman. the right ones work great on a Mercury. The wh 22 also works good on his motor. if you want to sell them let me know.
