Great video! One question I have is do you lubricate the valve stems when you reassemble? It seems there isn't consensus online and you seem to be successful with your technique. Thank you
Question: Valve lapped and set the valve lash. Piston cycles fine until I put in the spark plug is put in even part way I can really pull the starter as the piston no longer cycles. Is this a valve lash issue or something else? Thanks D
@@robbinsracing801you are right. Looks like what I thought was TDC looking through the spark plug port was not. I took off the header, put it to TDC and when I checked my lash was way off. Reset the lash with real TDC and Bam back in business. Thanks man!
@@robbinsracing801 i would like too see a Dyno pull showing these results. Last i checked on a combustion chamber motor you want as much Fuel & Air into cylinder & use maximum lift on cam lobe to open intake valve as far as you can too get max Combustion with out binding lifter & push rod & rocker arm when cam lobe is at max lift 😁 So why would you want less fuel & air into cylinder 🤔
@@scotts24d there’s more to engine operation that simply valve lift. Adjusting lash can affect things like valve overlap and duration. I know another builder that uses 0.006 as well due to testing showing better results. Meaning a better fuel air charge. At .002 lash they have can have reversion pushing exhaust gasses into the inlet reducing volume used for fuel and unused air.
Love these videos. They are so detailed. Keep them coming. Thank You!
Thanks for the positive feedback!!
thanks....your video is the best that i have found. Nice clear instructions. :)
Thanks great video!!!

Probably the lash, I would start over and make sure the piston is at top dead center on the compression stroke before you set the lash.

what kind of results had you find with this operation ?
The 2020 Season we ran this Lash we won 5 out of our 6 Club races
Why would you set your intake at 6 thousands your getting less fuel & air into cylinder & that results into less HP 🤔
Dyno and on track results say otherwise

@@robbinsracing801 Still like all your vids very clear on how things need to be fixed in Kart Racing 👍🏁🏁
