Is there anything else I should check while I wait for the carb kit?

Is there anything else I can check while I wait for carb kit to get here and what's a good way to test my muffler if it's little clogged

This is the one I use, made in Japan and has genuine mikuni jets and the needle you need. If your needle only has one slot that def can be your problem you should have 5.

Bought this kit also. Good to know that it has genuine mikuni jets and needle.

did it work well with your blaster?

My blaster would idle but stay revved up for a sec after I gave it some throttle. Had leaks all over, so I am guessing this is the culprit for me but I have not been able to work on my blaster since I installed the carb rebuild kit and leak tested my motor. Will report back as soon as I am able to.

Ok that carb kit fixed my problem but it has a lot of power and plug looks to be little lean it has stock jet what would be my options ?

Did you plug chop to confirm the Air Fuel Ratio or just pull the plug after a period of idling and look at it?

 

[Goldfox_32]

Well I tryed to plug chop but broke my saw lol but I have to have the air fuel screw on the tors backed out pretty far more than 2 turns to get it to not idle so high and still once it gets warm it idles high. And the plug was little grayish and white on end after the plug chop but I haven't got it cut yet cus it was so late last night and freezing cold and broke the blade I will get my band saw and cut it today but why am I haveing to turn that screw so far out

Is your air box lid on? With the DG pipe, depending on lid, premix, elevation, you will definitely need to up your jetting. You mybe able to see down in the plug with a magnifier and flashlight to see how it looks. Stock jet is going to be to lean more than likely

I live in Arkansas in the Ozarks not sure of elevation have to look. And I don't have air box lid on I premix 32:1 from glance down in plug looks to have slight brown ring but can't be for sure till I cut it open

what jet size would u recommend starting with I'm at 230 right now

 

[Blaaster]

300-310 main jet, a 230 is going to quickly fry a piston.

 

[Goldfox_32]

I have a 320 would that work?

Probably to big, but chop it there and see how it looks. Always better to start bigger.

 

[Goldfox_32]

Alright I'll get back to ya guys on the plug chop

 

[Fast6hand]

Just make sure your engine is air tight, carb is set up right, and you have a clean air filter. Otherwise results can vary. Good luck!
