Blaster stuck wide open

[mattsteibler26]

I gota blaster 1998 brand new top end, gaskets, reeds, and good carb and it sticks full throttle when i start it. What can be wrong

 

[Awk08]

throttle cable frayed
slide put into carb wrong
airscrew setting
huge airleak

 

[mattsteibler26]

It stuck wide open. cable seats perfectally and carb slide is put in right. all new gaskets. Idk where there can be an air leak

only a leakdown tester will tell that
is the oil injection deleted ??? if so, is that oil inlet on the carb plugged off

 

[Awk08]

common air leak areas include the reed/intake, base gasket, head gasket

was this engine broke in properly.....heat cycles, re-torque head and base bolts ????
and of course leaksdown tested

 

[mattsteibler26]

It was torqued right. and i blocked the oil outlet on the carb

 

[Awk08]

It was torqued right. and i blocked the oil outlet on the carb

re-torqued after the heat cycles ????
that allows the gaskets to expand/contract, and set themselves, it needs re-torqued afterwards

 

[mattsteibler26]

I didnt even break it in yet. It started then stuck full throttle. Only started like 3 times

 

[Awk08]

gotta be a carb problem then
pull it, disassemble, clean it, is the stock jetting in it, what jets are in it ???
is the brass washer under the main jet ???

 

[mattsteibler26]

Yes it is. and stock jetting

 

[blasterdemon7]

Just a shot in the dark but check your slide needle. Make sure it's there and it's gong onto the jet hole.

What about your idle screw it where it is supposed to be?

 

[mattsteibler26]

Its stock jetting. I took the main, pilot, and choke out and cleaned it.

 

[mattsteibler26]

Still stuck wide open after i cleaned the carb and made sure it was going into the bottom of the carb

 

[CARNZ]

can you actually watch the carb slide move when you have the air filter tube off? it would be pretty damn obvious if the carb itself was "stuck wide open" maybe your magneto side crank seal is bad

 

[mattsteibler26]

Yeah you can see it move. I can see it moving

 

[CARNZ]

then the carb isnt stuck wide open, it sounds like an air leak. check to see if ur mag side crank seal is bad, get a leakdown tester and check it THOROUGHLY before you start it again and risk that new topend

 

[mattsteibler26]

Do i have to split the cases to check that crank seal? and do i gota take off the magnito?

 

[EvilElvis]

sounds like a broke idle control screw

 

[mattsteibler26]

the idle control screw is broke on the tors. can that be my problem?
