pull the slide barrel out , screw the lsn in until it bottoms out and then count in half turns while unscrewing (richening) until you reach the desired setting .

same basic adjustment for the hsn .

I have a few novarossi engines. The one in question is a 21-5k. When measuring with calipers what is the tolerable size for the crank pin? Do you know that off the top of your head?

Thanks in advance!

when the smallest measurement is 4.92 and/or more than .04mm out of round i will rerod one last time ;)

Thanks again for all the help

Monty, are you going to add your engine "services" to the website? I'm guessing that it's still being built out? Nice looking by the way!

+1 on the website. It looks good :nod: :nod: :nod:

Hi Monty

Going on what you said i got a 9901 with 41021 today for my p5 and put in the 8mm and all i can say is wow really brought it to life

one question on the tune though it seems great high speed and good smoke and low end is also great however mid range it isnt making the power it does at very bottom and very top its not to lean or rich on the top or bottom it doesnt hesitate or bog or anything like that it just drops power slightly should i play with the mid range needle its still factory as i have not touched this one any advice will be great

Thanks Ben:)

site looks good Monty...glad to see it man:nod: ;) :tire:

it is a work in progress as you can see . i have faith it will be just how i want it before too long :nod:

thanks to an rc bro named shane for talking me into it :rolleyes::lol:
