question for carb guys
can you tell me how a blocked acc pump jet on #1 carb would affect the running of a gpr 1200...
the jet in the carb body #1 was 100% blocked
#2 was partially blocked but not as bad as other
got my buds ski apart and among other small defects have found above problem and not sure if this would cause the running problems we are having...
thanks in advance paul
p.s... bud dean is off sunning himself a million miles away while i work on his p.o.s ski ...

wont pull through the range and seems to pull harder top end if you back off the 3/4 gas and let it try to pick up speed that way,but never gets to full top speed..
runs great under no load on trailer...

I really don't think a blocked accelerator pump is going to cause the problems you described. I'd look elsewhere.

put my stock 1300 reeds in for him and got the pump jet unblocked so it works fine other than that to ME the ski seems good,will get new leads in post soon as i could only ohm out under no load,and water test again,
the only way i could have seen the ecc pump in #1 doing that was if it built up preasure and then dumped all the juice in one go and took the spark out but i am clutching at straws now as the following has been done..
carbs checked and re built inc new carb filter..
coils tested against resistance
new leads ordered as can only be tested with no load
crank phase checked
all connections checked on ski
slight chip on reeds...replaced
acc pump slight malfunction..repaired
any ideas or can you think of something i missed
