How do you seal the slide boot on the carb?
It's easier to do with the carb off....... At the end of the carb slide....take off the ball end that your linkage attaches to. Remove the carb slide boot and clean the boot and carb surface with denatured alcohol or nitro blast or even your favorite cleaner....as long as it doesn't leave a oily residue.:nod: Use some carb seal or silicone sealant and apply to the lip that the carb boot fits into and on the face of the carb where the boot will touch. Be careful not to put too much inside the lip off the carb....when the boot falls into the groove it may push some sealant out onto the slide. Slide the boot on....make sure of a good seal around the outside. Put it all back together and let it sit. :D |
AH...thank you wiseman.:D

The needles being wrong is what causes these engines to tune different. The "good tune" window is very small....and usually is found by using the lsn the most which is completely backwards from all other engines. Also...out of the box the needle settings are not far from race tune. People instinctivley reach to the hsn to lean out some during break in....it's almost perfect out of the box. These engines tune almost totally from the lsn.....sometimes even when you have high engine temps (280+ deg. F.) leaning the lsn will make it better if your hsn is set properly....usually around flush.:nod:

Iv done it the way brain has suggested ..and it works...I kinda had a hard time getting the lsn to turn smooth...so i removed it and installed a new oring..use a very light amount of grease(dont go carzy here),,and the lsn was so very easy to turn to find the sweet spot...
My friend has a 7port and gave up got a nova carb... Once you has it set.leave it..and your done.. thanks brain :) |

Is this the same procedure for a 5-port .21?

I want to clarify HSN flush. I usually take a hobby knife and run it across the HSN housing to "feel" if the needle is sticking up. Is there a set number of turns from fully closed that would make it easier? Do you just "eyeball" it? After running V-spec and RB's I am not used to such a sensitive engine :eek:

Hi Guys,
Just wondered if someone can give me some needle settings for a 21 3 port sport engine. I seem to have lost my way when tuning and now can't seem to get a steady idle or crisp take off. Thanks in advance |

Well i got to run my PTM GO .21 3 port race motor (with stock carb from Go)and all i can say again is WOW it was awesome.
We ran a 2 hour endurance race last night at the Nitro Pit here in AZ and i ran my jammin x1x buggy with that motor and my teamate and myself ran 6th overall. the motor had tons of power and was pretty good on the top end. i ran a novarossi 9886 pipe with standard header. it came off the track at 279 degrees f after the 2 hours. at first we had lean bog on bottom but tuned it out in the first 20 mins and was fine after that, even after 4 times that my right front shock fell off duhhhhhh here is a pic of my buggy and the motor from last night thnx GO and thnx Brian @ PTM awesome motor and i know i sure turns some heads out there. http://i199.photobucket.com/albums/a...w/100_0024.jpg http://i199.photobucket.com/albums/a...w/100_0028.jpg |
also here is a pic of my NEW jammin x2 truggy wit ha GO .25 6 port engine ready to run next club race
