Check your other thread about the batter issue you had I replied there regarding this. Bottom line it sounds pretty normal.

Sure there are also plenty of other nitro guys here. Try and get some video of any issues or success's to make it easier for people to help you or praise you and cheer you on.

That pop sound you mentioned is normal and just a function of the compression of the engine. If it DIDN'T make that noise you'd have much bigger problems.

Starting procedure for gas engines is a little different from nitro. I'm assuming you have the fuel lines installed correctly, fuel in the tank & the carb needles set to factory settings.

That being said, the carb on a gasser will have a butterfly valve ahead of the throttle valve called a choke. Close this valve so that the carburetor is restricted (choked). Turn ignition OFF. Move throttle to full power and spin the prop either by hand or with a starter to pull fuel into the carb. If it's been sitting for a long time it may take 20+ flips to get fuel to flow. 3-4 seconds with an electric starter should do it. You have now primed the engine.

Once the engine is primed, leave it choked, and turn the ignition ON. Reduce throttle to slightly above idle. Flip the prop by hand (carefully!) Or use a starter until the motor pops or even runs for a second or two. Once it pops, UN-choke the carb, and flip the prop again. It should start up.

Hope this helps.

Before you start it, suggest the following:

1) make sure its fresh gas and you have the right fuel/oil mixture.(use breakin first/regular)
2)check the gap(or replace the spark plug)
3) get a fresh battery for ignition.
4) I would order the replacement kit for the Walbro carb since the rubber is eaten up over time.
5) Make sure you have the right prop.
6 Go on line and find info for setting the correct turns for high and low idle screws. Read over and over how to tune(basically every time you adjust the highend adjust the low.
7) the midrange is the trouble(where it go fat or lean)
8) have a way of measuring temperature which will make it easier.

Really suggest you get an gas expert to help you(not a nitro guy) and for God's sake, that prop is a deadly weapon, think it out before you do.

Found a source that tells you why/what to look at and what happens.
