i need help guys,i just installed a new engine in my mt and when i pull the string on the starter it's very hard,what could be the cause?

Either the engine is flooded, or it is not oiled. If it is flooded, take out the glow plug and pull the cord until all the fuel comes out. If it is a new engine and there is no fuel in it, spray after run oil in the glow plug hole and into the carberator.

just a guess but when you say hard do you mean like brand new engine with a ****load of compression hard?

new engines are a b!**H to start. they have ultra high comp when new. probly just normal. may be hydro locked as well.

If it's really hard, be careful not to bend your connecting rod.

yeah its a brand new engine,but i put some after run oil before i started the engine and it started like four times and now when i pull the cord is really hard.

Loosen your plug just a hair then leave your igniter on for about 15 seconds then give 10 prime pulls with the exhaust pluged with your finger and then try to start it.

That had happend to me b4. It was like 3 weeks after i just bought my RC10gt, i just got done running mY car for about 10 minuets let i rest and came back.Then i tried to start it up agian and it was really hard to pull . 2 dayz later i found out my connecting rod had snapped[sm=angry.gif]
