Mcculloch Roadrunner

[mrhite65]

I found a Mcculloch Roadrunner but, It doesn't say what the cc's are. Does anyone know if it will be big enough for the friction drive?
I got it for $10 and it looks pretty new. It has an issue where it runs for a little bit but then dies. I figured it was worth $10 to figure it out.

run some carb cleaner though it.

1.pour out all the gas in it.
2.put in about two ounces of premix (oil and gas mixture)
3. shoot in a half dozen good squirts of carb cleaner.
4. Pump it through with the bulb a few times.
5. Remove the spark plug and pull it through a few times.
6. Empty the tank and add a couple of ounces fresh gasoline. See if it will start. if not shoot a few squirts of carb cleaner and do it all again.
7. usually that will do it. Not always but usually. Before I rebuilt or bought a new carb I would try it a few times.

I dont know the cc of the engine try google they might have a listing for the specifications.

According to that site it is 21.2 cc... its a little small but if you just want something to help you along it will work just fine. It won't pull hills without you pedaling but it will help you pedal them a lot easier.

Ok, Thanks!

That exploded view doesn't look right. The one I have has the pull start on the front. I also noticed on down that it says running time is 35-45 mins. Does that mean it will only run for that time period?

 

[deacon]

I have no idea what run time means someone else will have to answer that.

 

[mrhite65]

Maybe its how long it will run with a full tank of gas.

 

[deacon]

I bet it is cause shoes says she does ten miles on a tank and that would be about half and hour or a little more

Well, I don't know what happened to my last post but I'll do it again. I messed up! The name of the WW is Mcculloch Roadrunner III. Do you have the actual site I can get the info on?

 

[deacon]

I just googled it. You should do that you know what you need more than I do.

Found it, 28cc's! Not 30cc's but better than 25cc's.
