ive sealed this engine 2 times its not like i havent taken the time on it. its definatly not a i dont know how to tune issue there is a problem. and how am i bashing the product im saying id rather spend my money elsewhere because buying another carb after shipping i could have gotten another p5 for the amount of money and time ive put into this thing

and what are these clear instructions and if i have one does it get replaced? or what do i have to do

Whats seems to be the best plug for 21 sport motor?

I havent had any problems with my carb, just an oring problem when my hsn oring dried out and my hsn was loose. I green slimed it and now its fine.

It really sounds like your LSN is too lean. Richen it to the point where it doesnt bog at takeoff and tune the HSN from there.

but it does it weather its rich or lean it still bogs its wierd ill play with it this weekend if nothing works ill swap carbs from my novarossi thats in my box

these are the settings i run on the carb for about 3/4 gallon befor full blown race tune.

HSN-3/4 turn in from flush
LSN-2 turns in from flush
idle gap 1.5

once thye metal pinch is gone, and remember you don't want metal to metal pinch, just strait compresion, i will adjust the lsn in and leave the hSN where it is, this will set for a bit of high idle so then set the idle gap to 1mm and it will idle for days, and the bottom end will feel very strong and top end will be good with fading smoke at top of rpm range.

What pipe are you running on the engine? and plug?

What a JOKE! Your stupid comment makes absolutely NO SENSE. You should think before you type.

Cheese. Dana at racefactor WILL take care of you if you do have a carb issue. Everyone knows early Go's had carb issues. Why do you think they have been revised several times. Dana and Russel know it as well.

Go's are great value for the money and they are always trying to make them better.

hey cheese

after reading a couple of your posts it sounds to me like you've fallen it to a common trap with GO engines where your HSN is to lean and your LSN is to rich with a high Idle to compensate.

this tends to feel like your bottom end is lean bogging but it's actually the HSN causing the bog and the more you lean the top the worse it gets.

A couple of easy checks are to

#1. make sure the engine is up to temp 2-3 minutes of running minimum

#2. give the buggy a good run away and then back to you to make sure that it is well cleared out then bring it to a stop in front of you and listen to the revs.

#3 if the engine sounds like it's over reving (high idle)and then the revs drop back after 5-10 seconds it usually means that your bottom end is to rich.

#4 also try the pinch test - repeat step #2 but instead of listening to the revs pinch the fuel line at about 1/2" (10-15mm) from the fuel intake on the carb. It should only increase in rpm very slightly around 500- 1000 rpm max any more than this and your to rich also.

hope this helps

vnmsgt you have a pm

well im waiting on a response i spoke to a dealer with a bunch of go engines that had faulty low side needles so im waiting on a response to see if i have one of them.

turbo, p3 p6
std, a3 a8

os,odonnol,lrp , i run os with very luck, waiting on the GO turbo's

and im running a msr 1005 for pipe and os p3 for plug

yeh I know all about the LSN problems but they were on the 1st gen engines the Lsn had a corse thread which made it really hard to get a bottom end tune right.

I almost gave up on the Go range but with the new carb i haven't looked back. I'm still running them and my first Go 7port is still running strong after 10+ gallons (new bearings and rod at about 8 gallons) now I don't use anything else.

by the way the 1005 is ok on the Go engines but I've found that an 086 or the go 2047 seem to be a little easier to tune and you better runtime and performance haven't tried the new 0801 yet but will be soon

good luck

this isnt a thread issue its a needle size issue im going to run it tomorrow and see how it does if it doesnt do good im going to try another needle
