Mel Capone RC Nitro Engine Head Clearance

Changing the head shims can increase the engine's compression when shims are removed and decrease the compression when shims are added. There are plenty of ways to make this change. This is just how I do it.

Yeah give thank big man for the info think on doing some drag racing my self I got a jato 3.3 nitro gang

[@tonysands2837]

Awesome information bro much appreciated thanks for sharing I will definitely be checking this out on some of my engines cheers

The most easiest and fastest way is just use some solder, bend it in an L-shape, put it though the plug hole and turn the engine around. The squeezed piece of solder measured is your gap. From there you can add or remove the right amount of shims to your wished gap.

Thank you

How does the motor run if the gap is too close or too far away? Im new to this

[@melcapone54]

Too close and you will risk damaging the engine by crashing into the head button. Too close can also lead to too much heat and detonation, which is power loss. Too much clearance will decrease compression which could potentially lead to power loss but no potential damage to the engine.

Safer to stay at factory head deck settings until you are comfortable with making changes

@melcapone54 we do a lot of street/ no prep racing in NC.. But want to get into the prep racing like u guys @ the Rock. I want to build a direct drive small block, but I have to find the people who make the chassis

[@melcapone54]

@@bojones1709 call Josh Howard. He is the chassis supplier. 18153550430
