Does anyone else have a problem re-starting the Matrix arena after it has ran a while? When I stop for adjustments or run out of gas, the truggy is very hard to start and usually have to wait until it cools down. Help would be greatly appreciated.

Its hard to start period but most motors are easy to start when hot for me. They're already warm.

Are you priming the engine, usually you have to prime the engine everytime you restart the engine

You can try a different type of plug. That may help. Also, are you using a good quality fuel?
Your settings may also be off, possibly too lean in the low end or the idle needs to be opened up a bit.

Try those and get back with us here.

Thanks for the information. I will try the suggestions this weekend. I suspect the idle is a little low along with the low end needle needs some attention.

Thanks...

lol one pull after prime does it for mine
lol

What you have is "Vapor Lock". It's when the carb is so hot the fuel is being pushed away therefore not being able to crank over the engine. Two ways to solve this:

1. Let it cool
2. Let it cool

If you ever pour water, fuel or anything else to cause rapid cooling of your engine, you might end up kissing it goodbye.

The sh is very easy to start once tuned right.Its even easier to start when cold. Prime and should start on first pull.

Mine does,,lol I like the SH in RTR package. Now if someone could come up with a part # for the blank back plate to bump start is not a modification affair(cutting crank pin off)

here is a back plate that works on the sh. http://www.clermontmotorsports.com/s...k-plate/Detail
