K & B 3.5 OB

[cudacuda]

I have a mod 3.5 OB, it has exhaust throttle, little piston work, all rotate parts been balanced, but no tune pipe and I have it hanging on the back of VS1 ;}. The issue started last time out. The motor idle well during the short walk to the water as you bind down to lanch it will die five out six times. When it does hit the water running, it runs great, I've replaced al the fuel lines, new tank I'm thinking maybe gaskets are next has anyone ran into this before. I have heard everything from holding the boat level due it's K & B and it is just a K & B OB. Well I have been running K & B OB for years and this is the frist time I've ran into this issue. Oh yell this motor has ran good all winter and last season.

Thanks in advance for any help.

Check your PTO bearings. As they wear they tend to leak compression.Also with that exhaust throttle you need to keep the R's up so it won't load up.
