Blaster wb2 wont run right

[AKIN187]

just rebuilt but added a few things, cases were ported and epoxyed and added boyesen carbon reeds and stuffers. and put on 2 filters instead of the stock set-up.
do you need to rejet for any of these mods? it starts but has a horrible pull off of the bottom and wont pull up on the pipe when in the water! kinda at a loss.
any help or just comments would help me get in the right direction. thanks

sounds like it is starving for fuel on the low end. i would say yes to up jetting due to the filters, reeds and case porting. it will pull fuel / air a lot faster than before. did you rebuild the carbs? did you re set them to stock?

 

[AKIN187]

rebuilt them but didnt change any settings. the low is 115 in both and 135 in front and 137.5 in rear.

put it back to stock. you will never get thoses carbs to run correctly. they are un tuneable. or get a set of normal 44s.

What to stock? The carbs? Haven't touched them.

Any time you change the fuel / air flow characteristics of a motor you will have to rejet. Go up 3 jet sizes and start from there.

the stock air box is your best bet to make thoses carbs work sort of. case porting and reeds have an effect on air flow and that will effect your jetting. i ben there done that with the stock 44s. they will never run correctly. hell they dont even work very well on a stock b2.

never had issues with the 44's on my wife's old B2 other than normal diaphrams wearing out.

Well the jetting continues. I am up to 130 on low jet but keep running out of time to get it dialed in, it's a bit frustrating. Any body have any jetting ideas?

 

[ryan]

pop off is? what spring needle and seat?

 

[AKIN187]

Pop off is 35 spring is 65 and needle and seat is 1.5

pull out the reed stuffer thats causing half your issue
put in a 130 low speed
115 high
2.5 n/s
95 gram spring
go ride the 44s you have will go very well they are a great setup and I run them on alot of surf boats here in australia

 

[AKIN187]

What affect does the reed stuffer have?

 

[waxhead]

you lose acceleration and about 150 rpm on top
